We divide 3872 by 89
We want to figure out the number of times 3872 can be divided by 89.

Going ahead to step 1:
89 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 89

Let's proceed to step 2:
If we divide 38 by 89, we get 0 and a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 89

Going ahead to step 3:
If we divide 387 by 89, we get 4 and a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 356 from 387, we get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 89

Step 4:
The number 89 fits into 312 3 times, leaving a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we take 267 away from 312, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 5:
If we divide 450 by 89, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 43.5
Subtract 445 from 450 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
89 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 43.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
500 divided by 89 is 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 43.505
Subtract 445 from 500 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 8:
550 divided by 89 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 43.5056
The remainder is 16 after subtracting 534 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 89, we get 1 and a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 43.50561
Subtracting 89 from 160 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 10:
When dividing 710 by 89, we get 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 43.505617
Deduct 623 from 710 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 11:
The number 89 fits into 870 9 times, leaving a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 43.5056179
If we take 801 away from 870, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
If we divide 690 by 89, we get 7 and a remainder of 67.
The next digit of our result is 7. 
Result so far: 43.50561797
Subtracting 623 from 690 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The quotient of the division is 43.50561797, and the remainder is 6.7e-08.
