Latihan tambahan

个位不够除 = sa tidak cukup 被除数的个位比除数小时，商的个位写 0，并在后面点上小数点；然后把个位和十分位合起来看成“几十个零点一”去除。商的每一位都要对着被除数的那一位。 例子：2.4 ÷ 8 → 2 不够除，写 0.；24 ÷ 8 = 3 → 0.3。 注意：商的 0 只写在个位；十分位不要多写一个 0。

the ones are too small = sa tidak cukup When the ones digit is smaller than the divisor, write 0 in the ones of the quotient and put in the point. Then treat the ones and tenths together as tenths and divide. Each digit of the quotient sits above its place. Example: 2.4 ÷ 8: 2 is too small, write 0 and the point; 24 ÷ 8 = 3, so 0.3. Watch out: the 0 goes only in the ones; do not add an extra 0 in the tenths.

补零继续除 = tambah sifar 整数除不尽时，可以在被除数后面点上小数点、补 0，把余数和补上的 0 合起来继续除，直到余数是 0 为止。补几个 0 都不会改变被除数的大小。 例子：9 ÷ 8 → 9.000 ÷ 8 → 1 余 1，10 ÷ 8 = 1 余 2，20 ÷ 8 = 2 余 4，40 ÷ 8 = 5 → 1.125。 注意：余数不能直接写在小数点后面，要继续除才能得到小数部分。

add zeros and keep dividing = tambah sifar When a whole number does not divide exactly, put a decimal point and zeros after it, then bring each zero down next to the remainder and keep dividing until the remainder is 0. The zeros do not change the size of the number. Example: 9 ÷ 8 = 9.000 ÷ 8: 1 r 1, 10 ÷ 8 = 1 r 2, 20 ÷ 8 = 2 r 4, 40 ÷ 8 = 5, giving 1.125. Watch out: the remainder cannot just be written after the point; keep dividing to get the decimal part.

商中间的零 = sifar di tengah 长除法中，每移下一个数字，商就要写一位。如果移下来的数比除数小，不够除，商的这一位就写 0，再移下下一个数字一起除。 例子：18.27 ÷ 9 → 18 ÷ 9 = 2，点小数点，2 不够除写 0，27 ÷ 9 = 3 → 2.03。 注意：不够除时商写 0，这个 0 不能漏，不然数位全部错开。

a zero in the middle = sifar di tengah In long division every digit you bring down gives one digit in the quotient. If the number brought down is smaller than the divisor, write 0 in that place of the quotient and bring down the next digit. Example: 18.27 ÷ 9: 18 ÷ 9 = 2, put in the point, 2 is too small so write 0, 27 ÷ 9 = 3, giving 2.03. Watch out: do not leave out that 0, or every digit after it moves to the wrong place.

除以一千 = bahagi seribu 整数的小数点在个位后面。除以一千，小数点往左移三位；如果数字不够，前面补 0，个位写 0。 例子：64 ÷ 1 000 = 0.064；2 350 ÷ 1 000 = 2.35。 注意：数一数一千后面有三个 0，小数点就要移三位，不多也不少。

divide by one thousand = bahagi seribu A whole number has its point after the ones. Dividing by 1 000 moves the point three places left; if there are not enough digits, write zeros in front and a 0 in the ones. Example: 64 ÷ 1 000 = 0.064; 2 350 ÷ 1 000 = 2.35. Watch out: 1 000 has three zeros, so move the point exactly three places.

应用题 = masalah 把布平均剪成几条，每条多长，要用除法：总长 ÷ 条数。用长除法，商的小数点对齐被除数的小数点。算完用“每条长度 × 条数”检查。 例子：8.4 m 平均剪成 4 条 → 8.4 ÷ 4 = 2.1 m。 注意：平均分是除法，不是乘法；商的小数点要对齐。

a word problem = masalah Cutting the cloth into equal pieces and finding each length needs division: total length ÷ number of pieces. Use long division with the point lined up, then check by multiplying the length of one piece by the number of pieces. Example: 8.4 m cut into 4 equal pieces: 8.4 ÷ 4 = 2.1 m. Watch out: sharing equally is division, not multiplication, and line up the point in the quotient.
