89682662 ÷ 640 
We want to divide 89682662 by 640.

Step 1:
The number 640 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 640

Moving on to step 2:
89 divided by 640 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Grab the next digit (6) from the dividend, add it to 89, then carry on: 896 / 640

Going ahead to step 3:
The number 640 fits into 896 1 times, leaving a remainder of 256.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 640 from 896 and we're left with 256.
Include the next digit (8) from the dividend after 256, then repeat: 2568 / 640

Step 4:
When dividing 2568 by 640, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2560 from 2568, we get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 640

On to step 5:
640 goes into 82 0 times with a remainder of 82.
The next digit of our result is 0. 
Result so far: 140.0
Deduct 0 from 82 and we're left with 82.
Take the next digit (6) from the dividend and append it to 82, then repeat: 826 / 640

Let's proceed to step 6:
When dividing 826 by 640, we get 1 with a remainder of 186.
The next digit of our result is 1. 
Result so far: 1401.0
Deduct 640 from 826 and we're left with 186.
Include the next digit (6) from the dividend after 186, then repeat: 1866 / 640

On to step 7:
When dividing 1866 by 640, we get 2 with a remainder of 586.
Record the quotient 2 as the next digit in the result. 
Result so far: 14012.0
Deduct 1280 from 1866 and we're left with 586.
Append the next digit (2) from the dividend to 586 and continue with: 5862 / 640

Advancing to step 8:
When dividing 5862 by 640, we get 9 with a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 140129.0
If we subtract 5760 from 5862, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 9:
If we divide 1020 by 640, we get 1 and a remainder of 380.
The next digit of our result is 1. 
Result so far: 140129.1
Subtract 640 from 1020 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 10:
640 can be fit into 3800 5 times, resulting in a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 140129.15
Subtracting 3200 from 3800 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 11:
The number 640 fits into 6000 9 times, leaving a remainder of 240.
Use 9 as the next digit of our solution. 
Result so far: 140129.159
If we subtract 5760 from 6000, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
When dividing 2400 by 640, we get 3 with a remainder of 480.
The number 3 becomes the next digit in our result. 
Result so far: 140129.1593
Subtract 1920 from 2400 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 13:
4800 divided by 640 is 7 with a remainder of 320.
Put 7 as the next digit of the answer. 
Result so far: 140129.15937
Subtracting 4480 from 4800 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 14:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 140129.159375
Subtract 3200 from 3200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 15:
0 divided by 640 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 140129.159375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 16:
640 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 140129.159375
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 140129.159375, with a leftover of 0.0.
