We look at the division of 71422621 by 88 
Our goal is to divide 71422621 by 88.

Step 1:
When dividing 7 by 88, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 88

Going ahead to step 2:
When dividing 71 by 88, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 88

Advancing to step 3:
88 goes into 714 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 704 from 714 leaves us with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 88

Step 4:
If we divide 102 by 88, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 88 away from 102, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 88

Let's proceed to step 5:
If we divide 142 by 88, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 811.0
Deduct 88 from 142 and we're left with 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 88

On to step 6:
546 divided by 88 is 6 with a remainder of 18.
The next digit of our result is 6. 
Result so far: 8116.0
Deduct 528 from 546 and we're left with 18.
Take the next digit (2) from the dividend and append it to 18, then repeat: 182 / 88

On to step 7:
The number 88 fits into 182 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 81162.0
Deduct 176 from 182 and we're left with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 88

Going ahead to step 8:
88 can be fit into 61 0 times, resulting in a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 811620.0
Subtracting 0 from 61 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
88 goes into 610 6 times with a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 811620.6
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 10:
When dividing 820 by 88, we get 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 811620.69
Subtract 792 from 820 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
88 can be fit into 280 3 times, resulting in a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 811620.693
Subtracting 264 from 280 leaves us 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.

Step 12:
If we divide 160 by 88, we get 1 and a remainder of 72.
Write down 1 as next digit of the result. 
Result so far: 811620.6931
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.

Moving on to step 13:
When dividing 720 by 88, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 811620.69318
If we subtract 704 from 720, we 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.

Let's proceed to step 14:
If we divide 160 by 88, we get 1 and a remainder of 72.
The next digit of our result is 1. 
Result so far: 811620.693181
Subtracting 88 from 160 leaves us 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.

On to step 15:
The number 88 fits into 720 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 811620.6931818
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 16:
88 goes into 160 1 times with a remainder of 72.
Use 1 as the next digit of our solution. 
Result so far: 811620.69318181
The remainder is 72 after subtracting 88 from 160.
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 811620.69318181 with a remainder of 7.2e-08.
