We look at the division of 89133841 by 640 
We want to divide 89133841 by 640.

Going ahead to step 1:
When dividing 8 by 640, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
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:
640 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 89, we end up with 89.
Bring next digit (1) of the dividend behind the 89 and repeat the process: 891 / 640

Going ahead to step 3:
If we divide 891 by 640, we get 1 and a remainder of 251.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 640 from 891 to get 251.
Grab the next digit (3) from the dividend, add it to 251, then carry on: 2513 / 640

Let's proceed to step 4:
640 can be fit into 2513 3 times, resulting in a remainder of 593.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 1920 from 2513 leaves us with 593.
Take the next digit (3) from the dividend and append it to 593, then repeat: 5933 / 640

Let's proceed to step 5:
If we divide 5933 by 640, we get 9 and a remainder of 173.
The next digit of our result is 9. 
Result so far: 139.0
Subtracting 5760 from 5933 leaves us with 173.
Fetch the next digit (8) from the dividend, attach it to 173 and continue: 1738 / 640

Going ahead to step 6:
The number 640 fits into 1738 2 times, leaving a remainder of 458.
The number 2 becomes the next digit in our result. 
Result so far: 1392.0
The remainder is 458 after subtracting 1280 from 1738.
Include the next digit (4) from the dividend after 458, then repeat: 4584 / 640

On to step 7:
640 goes into 4584 7 times with a remainder of 104.
Put 7 as the next digit of the answer. 
Result so far: 13927.0
Subtracting 4480 from 4584 leaves us with 104.
Take the next digit (1) from the dividend and append it to 104, then repeat: 1041 / 640

On to step 8:
640 goes into 1041 1 times with a remainder of 401.
The next digit of our result is 1. 
Result so far: 139271.0
Subtract 640 from 1041 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Let's proceed to step 9:
If we divide 4010 by 640, we get 6 and a remainder of 170.
Use 6 as the next digit of our solution. 
Result so far: 139271.6
Deduct 3840 from 4010 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 10:
The number 640 fits into 1700 2 times, leaving a remainder of 420.
Record the quotient 2 as the next digit in the result. 
Result so far: 139271.62
Deduct 1280 from 1700 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 11:
If we divide 4200 by 640, we get 6 and a remainder of 360.
Put 6 as the next digit of the answer. 
Result so far: 139271.626
If we subtract 3840 from 4200, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 12:
640 goes into 3600 5 times with a remainder of 400.
The next digit of our result is 5. 
Result so far: 139271.6265
If we take 3200 away from 3600, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
The number 640 fits into 4000 6 times, leaving a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 139271.62656
If we take 3840 away from 4000, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
1600 divided by 640 is 2 with a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 139271.626562
Subtracting 1280 from 1600 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.

Step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 139271.6265625
If we subtract 3200 from 3200, we 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.

On to step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 139271.6265625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 139271.6265625 and a remainder of 0.0.
