We look at the division of 90299738 by 255 
We want to divide 90299738 by 255.

Step 1:
255 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 255

Moving on to step 2:
90 divided by 255 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 255

Advancing to step 3:
255 can be fit into 902 3 times, resulting in a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 137 after subtracting 765 from 902.
Append the next digit (9) from the dividend to 137 and continue with: 1379 / 255

Let's proceed to step 4:
If we divide 1379 by 255, we get 5 and a remainder of 104.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtracting 1275 from 1379 leaves us with 104.
Grab the next digit (9) from the dividend, add it to 104, then carry on: 1049 / 255

Going ahead to step 5:
255 can be fit into 1049 4 times, resulting in a remainder of 29.
Write down 4 as next digit of the result. 
Result so far: 354.0
Deduct 1020 from 1049 and we're left with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 255

Step 6:
297 divided by 255 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 3541.0
If we subtract 255 from 297, we get 42.
Include the next digit (3) from the dividend after 42, then repeat: 423 / 255

On to step 7:
255 can be fit into 423 1 times, resulting in a remainder of 168.
Write down 1 as next digit of the result. 
Result so far: 35411.0
The remainder is 168 after subtracting 255 from 423.
Take the next digit (8) from the dividend and append it to 168, then repeat: 1688 / 255

On to step 8:
When dividing 1688 by 255, we get 6 with a remainder of 158.
The number 6 becomes the next digit in our result. 
Result so far: 354116.0
Deduct 1530 from 1688 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 9:
If we divide 1580 by 255, we get 6 and a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 354116.6
Subtract 1530 from 1580 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.

Step 10:
500 divided by 255 is 1 with a remainder of 245.
Write down 1 as next digit of the result. 
Result so far: 354116.61
The remainder is 245 after subtracting 255 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 11:
2450 divided by 255 is 9 with a remainder of 155.
The next digit of our result is 9. 
Result so far: 354116.619
If we subtract 2295 from 2450, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 12:
The number 255 fits into 1550 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 354116.6196
Deduct 1530 from 1550 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
255 can be fit into 200 0 times, resulting in a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 354116.6196
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 14:
2000 divided by 255 is 7 with a remainder of 215.
Put 7 as the next digit of the answer. 
Result so far: 354116.619607
Deduct 1785 from 2000 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 15:
The number 255 fits into 2150 8 times, leaving a remainder of 110.
The next digit of our result is 8. 
Result so far: 354116.6196078
Subtracting 2040 from 2150 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 16:
The number 255 fits into 1100 4 times, leaving a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 354116.61960784
Deduct 1020 from 1100 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 354116.61960784 with a balance of 8e-08.
