We're dividing 90270063 by 904 
Let's see how many times 904 fits into 90270063.

Moving on to step 1:
The number 904 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 904

On to step 2:
904 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 904

Advancing to step 3:
The number 904 fits into 902 0 times, leaving a remainder of 902.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 902 to get 902.
Append the next digit (7) from the dividend to 902 and continue with: 9027 / 904

On to step 4:
If we divide 9027 by 904, we get 9 and a remainder of 891.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 891 after subtracting 8136 from 9027.
Append the next digit (0) from the dividend to 891 and continue with: 8910 / 904

On to step 5:
If we divide 8910 by 904, we get 9 and a remainder of 774.
Use 9 as the next digit of our solution. 
Result so far: 99.0
The remainder is 774 after subtracting 8136 from 8910.
Take the next digit (0) from the dividend and append it to 774, then repeat: 7740 / 904

Going ahead to step 6:
When dividing 7740 by 904, we get 8 with a remainder of 508.
The next digit of our result is 8. 
Result so far: 998.0
The remainder is 508 after subtracting 7232 from 7740.
Bring next digit (6) of the dividend behind the 508 and repeat the process: 5086 / 904

On to step 7:
904 goes into 5086 5 times with a remainder of 566.
The number 5 becomes the next digit in our result. 
Result so far: 9985.0
Subtract 4520 from 5086 to get 566.
Grab the next digit (3) from the dividend, add it to 566, then carry on: 5663 / 904

On to step 8:
If we divide 5663 by 904, we get 6 and a remainder of 239.
Record the quotient 6 as the next digit in the result. 
Result so far: 99856.0
Subtracting 5424 from 5663 leaves us with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Advancing to step 9:
904 goes into 2390 2 times with a remainder of 582.
Use 2 as the next digit of our solution. 
Result so far: 99856.2
Subtract 1808 from 2390 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Let's proceed to step 10:
If we divide 5820 by 904, we get 6 and a remainder of 396.
Write down 6 as next digit of the result. 
Result so far: 99856.26
Deduct 5424 from 5820 and we're left with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

On to step 11:
3960 divided by 904 is 4 with a remainder of 344.
Put 4 as the next digit of the answer. 
Result so far: 99856.264
The remainder is 344 after subtracting 3616 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 12:
904 can be fit into 3440 3 times, resulting in a remainder of 728.
The next digit of our result is 3. 
Result so far: 99856.2643
The remainder is 728 after subtracting 2712 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Going ahead to step 13:
If we divide 7280 by 904, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 99856.26438
The remainder is 48 after subtracting 7232 from 7280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
904 goes into 480 0 times with a remainder of 480.
Record the quotient 0 as the next digit in the result. 
Result so far: 99856.26438
If we subtract 0 from 480, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 15:
If we divide 4800 by 904, we get 5 and a remainder of 280.
Record the quotient 5 as the next digit in the result. 
Result so far: 99856.2643805
Deduct 4520 from 4800 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 16:
If we divide 2800 by 904, we get 3 and a remainder of 88.
Write down 3 as next digit of the result. 
Result so far: 99856.26438053
If we subtract 2712 from 2800, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 99856.26438053 with a balance of 8.8e-08.
