We look at the division of 51235153 by 220 
We want to divide 51235153 by 220.

Moving on to step 1:
The number 220 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 220

Step 2:
The number 220 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 220

On to step 3:
512 divided by 220 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 440 away from 512, we end up with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 220

Moving on to step 4:
If we divide 723 by 220, we get 3 and a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 660 away from 723, we end up with 63.
Append the next digit (5) from the dividend to 63 and continue with: 635 / 220

Moving on to step 5:
220 can be fit into 635 2 times, resulting in a remainder of 195.
The next digit of our result is 2. 
Result so far: 232.0
Subtract 440 from 635 to get 195.
Bring next digit (1) of the dividend behind the 195 and repeat the process: 1951 / 220

Moving on to step 6:
The number 220 fits into 1951 8 times, leaving a remainder of 191.
Record the quotient 8 as the next digit in the result. 
Result so far: 2328.0
Deduct 1760 from 1951 and we're left with 191.
Append the next digit (5) from the dividend to 191 and continue with: 1915 / 220

Advancing to step 7:
1915 divided by 220 is 8 with a remainder of 155.
Write down 8 as next digit of the result. 
Result so far: 23288.0
Deduct 1760 from 1915 and we're left with 155.
Append the next digit (3) from the dividend to 155 and continue with: 1553 / 220

Going ahead to step 8:
220 goes into 1553 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 232887.0
Subtract 1540 from 1553 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 9:
If we divide 130 by 220, we get 0 and a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 232887.0
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 10:
220 can be fit into 1300 5 times, resulting in a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 232887.05
If we subtract 1100 from 1300, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 11:
2000 divided by 220 is 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 232887.059
The remainder is 20 after subtracting 1980 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
220 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 232887.059
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 13:
The number 220 fits into 2000 9 times, leaving a remainder of 20.
The next digit of our result is 9. 
Result so far: 232887.05909
If we take 1980 away from 2000, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
220 can be fit into 200 0 times, resulting in a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 232887.05909
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 15:
220 goes into 2000 9 times with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 232887.0590909
The remainder is 20 after subtracting 1980 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
The number 220 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 232887.0590909
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

After the division, we end up with 232887.0590909 and a remainder of 2e-07.
