Let's divide 88896146 by 90
We want to figure out the number of times 88896146 can be divided by 90.

On to step 1:
If we divide 8 by 90, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 90

Going ahead to step 2:
If we divide 88 by 90, we get 0 and 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 (8) from the dividend to 88 and continue with: 888 / 90

Going ahead to step 3:
When dividing 888 by 90, we get 9 with a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 78 after subtracting 810 from 888.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 90

Step 4:
90 can be fit into 789 8 times, resulting in a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtract 720 from 789 to get 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 90

Advancing to step 5:
When dividing 696 by 90, we get 7 with a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
Deduct 630 from 696 and we're left with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 90

On to step 6:
When dividing 661 by 90, we get 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 9877.0
Deduct 630 from 661 and we're left with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 90

Step 7:
90 can be fit into 314 3 times, resulting in a remainder of 44.
The next digit of our result is 3. 
Result so far: 98773.0
Subtract 270 from 314 to get 44.
Fetch the next digit (6) from the dividend, attach it to 44 and continue: 446 / 90

Step 8:
If we divide 446 by 90, we get 4 and a remainder of 86.
Record the quotient 4 as the next digit in the result. 
Result so far: 987734.0
Subtract 360 from 446 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 9:
When dividing 860 by 90, we get 9 with a remainder of 50.
Use 9 as the next digit of our solution. 
Result so far: 987734.9
Subtract 810 from 860 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 10:
If we divide 500 by 90, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 987734.95
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
If we divide 500 by 90, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 987734.955
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 987734.955 and a remainder of 0.005.
