Let's divide 640032 by 89
We want to divide 640032 by 89.

Advancing to step 1:
89 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 89

Going ahead to step 2:
When dividing 64 by 89, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 89

Moving on to step 3:
640 divided by 89 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 623 from 640 to get 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 89

Going ahead to step 4:
89 can be fit into 170 1 times, resulting in a remainder of 81.
The next digit of our result is 1. 
Result so far: 71.0
If we subtract 89 from 170, we get 81.
Grab the next digit (3) from the dividend, add it to 81, then carry on: 813 / 89

Moving on to step 5:
When dividing 813 by 89, we get 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 719.0
Subtracting 801 from 813 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 89

Going ahead to step 6:
If we divide 122 by 89, we get 1 and a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 7191.0
Deduct 89 from 122 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
89 goes into 330 3 times with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 7191.3
If we subtract 267 from 330, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 8:
630 divided by 89 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 7191.37
If we subtract 623 from 630, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
The number 89 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 7191.37
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
89 goes into 700 7 times with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 7191.3707
The remainder is 77 after subtracting 623 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 11:
89 can be fit into 770 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 7191.37078
Deduct 712 from 770 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
The number 89 fits into 580 6 times, leaving a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 7191.370786
If we subtract 534 from 580, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
When dividing 460 by 89, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 7191.3707865
Deduct 445 from 460 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
150 divided by 89 is 1 with a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 7191.37078651
Subtract 89 from 150 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 7191.37078651 and a remainder of 6.1e-08.
