90343034 divided by 255 
We want to figure out the number of times 90343034 can be divided by 255.

On to step 1:
255 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 255

Step 2:
255 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Append the next digit (3) from the dividend to 90 and continue with: 903 / 255

Step 3:
255 can be fit into 903 3 times, resulting in a remainder of 138.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 765 from 903 leaves us with 138.
Include the next digit (4) from the dividend after 138, then repeat: 1384 / 255

Let's proceed to step 4:
If we divide 1384 by 255, we get 5 and a remainder of 109.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 1275 from 1384 and we're left with 109.
Grab the next digit (3) from the dividend, add it to 109, then carry on: 1093 / 255

Let's proceed to step 5:
The number 255 fits into 1093 4 times, leaving a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 354.0
Subtract 1020 from 1093 to get 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 255

Advancing to step 6:
255 can be fit into 730 2 times, resulting in a remainder of 220.
The number 2 becomes the next digit in our result. 
Result so far: 3542.0
Subtracting 510 from 730 leaves us with 220.
Fetch the next digit (3) from the dividend, attach it to 220 and continue: 2203 / 255

Advancing to step 7:
2203 divided by 255 is 8 with a remainder of 163.
Record the quotient 8 as the next digit in the result. 
Result so far: 35428.0
Deduct 2040 from 2203 and we're left with 163.
Grab the next digit (4) from the dividend, add it to 163, then carry on: 1634 / 255

Moving on to step 8:
If we divide 1634 by 255, we get 6 and a remainder of 104.
Record the quotient 6 as the next digit in the result. 
Result so far: 354286.0
If we take 1530 away from 1634, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 9:
1040 divided by 255 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 354286.4
If we take 1020 away from 1040, we end up 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.

Step 10:
255 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 354286.4
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
If we divide 2000 by 255, we get 7 and a remainder of 215.
Write down 7 as next digit of the result. 
Result so far: 354286.407
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.

Step 12:
The number 255 fits into 2150 8 times, leaving a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 354286.4078
Subtract 2040 from 2150 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 13:
When dividing 1100 by 255, we get 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 354286.40784
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.

Let's proceed to step 14:
255 can be fit into 800 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 354286.407843
Subtracting 765 from 800 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 15:
If we divide 350 by 255, we get 1 and a remainder of 95.
Use 1 as the next digit of our solution. 
Result so far: 354286.4078431
The remainder is 95 after subtracting 255 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 16:
255 goes into 950 3 times with a remainder of 185.
The number 3 becomes the next digit in our result. 
Result so far: 354286.40784313
The remainder is 185 after subtracting 765 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

In conclusion, the division gives 354286.40784313 with a balance of 1.85e-07.
