We look at the division of 88790389 by 817 
We want to divide 88790389 by 817.

Advancing to step 1:
817 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 817

Advancing to step 2:
When dividing 88 by 817, we get 0 with a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Include the next digit (7) from the dividend after 88, then repeat: 887 / 817

Let's proceed to step 3:
The number 817 fits into 887 1 times, leaving a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 817 from 887 and we're left with 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 817

Step 4:
709 divided by 817 is 0 with a remainder of 709.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 709, we get 709.
Append the next digit (0) from the dividend to 709 and continue with: 7090 / 817

Moving on to step 5:
If we divide 7090 by 817, we get 8 and a remainder of 554.
The next digit of our result is 8. 
Result so far: 108.0
Deduct 6536 from 7090 and we're left with 554.
Include the next digit (3) from the dividend after 554, then repeat: 5543 / 817

Let's proceed to step 6:
When dividing 5543 by 817, we get 6 with a remainder of 641.
Record the quotient 6 as the next digit in the result. 
Result so far: 1086.0
If we subtract 4902 from 5543, we get 641.
Fetch the next digit (8) from the dividend, attach it to 641 and continue: 6418 / 817

On to step 7:
6418 divided by 817 is 7 with a remainder of 699.
Write down 7 as next digit of the result. 
Result so far: 10867.0
Subtracting 5719 from 6418 leaves us with 699.
Bring next digit (9) of the dividend behind the 699 and repeat the process: 6999 / 817

Going ahead to step 8:
6999 divided by 817 is 8 with a remainder of 463.
Record the quotient 8 as the next digit in the result. 
Result so far: 108678.0
The remainder is 463 after subtracting 6536 from 6999.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Advancing to step 9:
817 can be fit into 4630 5 times, resulting in a remainder of 545.
Write down 5 as next digit of the result. 
Result so far: 108678.5
Deduct 4085 from 4630 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Advancing to step 10:
When dividing 5450 by 817, we get 6 with a remainder of 548.
The next digit of our result is 6. 
Result so far: 108678.56
If we subtract 4902 from 5450, we get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Advancing to step 11:
The number 817 fits into 5480 6 times, leaving a remainder of 578.
Record the quotient 6 as the next digit in the result. 
Result so far: 108678.566
Subtracting 4902 from 5480 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

The final outcome is 108678.566, with a leftover of 0.0578.
