We look at the division of 88499186 by 816 
Let's see how many times 816 fits into 88499186.

On to step 1:
When dividing 8 by 816, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 816

On to step 2:
88 divided by 816 is 0 with a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 88 and we're left with 88.
Append the next digit (4) from the dividend to 88 and continue with: 884 / 816

Advancing to step 3:
816 goes into 884 1 times with a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 68 after subtracting 816 from 884.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 816

On to step 4:
When dividing 689 by 816, we get 0 with a remainder of 689.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 689, we end up with 689.
Bring next digit (9) of the dividend behind the 689 and repeat the process: 6899 / 816

Moving on to step 5:
The number 816 fits into 6899 8 times, leaving a remainder of 371.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 371 after subtracting 6528 from 6899.
Include the next digit (1) from the dividend after 371, then repeat: 3711 / 816

Moving on to step 6:
If we divide 3711 by 816, we get 4 and a remainder of 447.
The next digit of our result is 4. 
Result so far: 1084.0
Subtract 3264 from 3711 to get 447.
Take the next digit (8) from the dividend and append it to 447, then repeat: 4478 / 816

Going ahead to step 7:
The number 816 fits into 4478 5 times, leaving a remainder of 398.
The number 5 becomes the next digit in our result. 
Result so far: 10845.0
Deduct 4080 from 4478 and we're left with 398.
Append the next digit (6) from the dividend to 398 and continue with: 3986 / 816

Let's proceed to step 8:
816 can be fit into 3986 4 times, resulting in a remainder of 722.
Record the quotient 4 as the next digit in the result. 
Result so far: 108454.0
The remainder is 722 after subtracting 3264 from 3986.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 9:
When dividing 7220 by 816, we get 8 with a remainder of 692.
Use 8 as the next digit of our solution. 
Result so far: 108454.8
Deduct 6528 from 7220 and we're left with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Moving on to step 10:
816 goes into 6920 8 times with a remainder of 392.
Write down 8 as next digit of the result. 
Result so far: 108454.88
The remainder is 392 after subtracting 6528 from 6920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

After the division, we end up with 108454.88 and a remainder of 0.392.
