We look at the division of 521109 by 88 
We want to divide 521109 by 88.

Step 1:
5 divided by 88 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 88

Step 2:
88 can be fit into 52 0 times, resulting in a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 88

Let's proceed to step 3:
88 goes into 521 5 times with a remainder of 81.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 440 from 521 leaves us with 81.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 88

Let's proceed to step 4:
88 goes into 811 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtract 792 from 811 to get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 88

Going ahead to step 5:
If we divide 190 by 88, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 592.0
Subtracting 176 from 190 leaves us with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 88

Going ahead to step 6:
The number 88 fits into 149 1 times, leaving a remainder of 61.
The next digit of our result is 1. 
Result so far: 5921.0
Subtract 88 from 149 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.

Step 7:
610 divided by 88 is 6 with a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 5921.6
The remainder is 82 after subtracting 528 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 8:
The number 88 fits into 820 9 times, leaving a remainder of 28.
Record the quotient 9 as the next digit in the result. 
Result so far: 5921.69
Deduct 792 from 820 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
88 goes into 280 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 5921.693
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
88 can be fit into 160 1 times, resulting in a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 5921.6931
Deduct 88 from 160 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
If we divide 720 by 88, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 5921.69318
If we take 704 away from 720, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
160 divided by 88 is 1 with a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 5921.693181
If we subtract 88 from 160, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
88 goes into 720 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 5921.6931818
Deduct 704 from 720 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
When dividing 160 by 88, we get 1 with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 5921.69318181
Subtract 88 from 160 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 5921.69318181 with a remainder of 7.2e-08.
