We look at the division of 80685451 by 88 
Our goal is to divide 80685451 by 88.

Advancing to step 1:
When dividing 8 by 88, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 88

Advancing to step 2:
The number 88 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (6) from the dividend and append it to 80, then repeat: 806 / 88

On to step 3:
88 can be fit into 806 9 times, resulting in a remainder of 14.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 14 after subtracting 792 from 806.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 88

Going ahead to step 4:
148 divided by 88 is 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtract 88 from 148 to get 60.
Include the next digit (5) from the dividend after 60, then repeat: 605 / 88

Step 5:
605 divided by 88 is 6 with a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 916.0
If we take 528 away from 605, we end up with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 88

On to step 6:
774 divided by 88 is 8 with a remainder of 70.
The number 8 becomes the next digit in our result. 
Result so far: 9168.0
Subtracting 704 from 774 leaves us with 70.
Bring next digit (5) of the dividend behind the 70 and repeat the process: 705 / 88

Let's proceed to step 7:
705 divided by 88 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 91688.0
Subtracting 704 from 705 leaves us with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 88

Advancing to step 8:
11 divided by 88 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 916880.0
If we subtract 0 from 11, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
88 can be fit into 110 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 916880.1
Deduct 88 from 110 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
220 divided by 88 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 916880.12
The remainder is 44 after subtracting 176 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
88 goes into 440 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 916880.125
The remainder is 0 after subtracting 440 from 440.
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 12:
When dividing 0 by 88, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 916880.125
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.

Advancing to step 13:
If we divide 0 by 88, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 916880.125
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.

The quotient of the division is 916880.125, and the remainder is 0.0.
