Let's divide 32040304 by 90
We want to figure out the number of times 32040304 can be divided by 90.

Advancing to step 1:
If we divide 3 by 90, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 90

Going ahead to step 2:
When dividing 32 by 90, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 90

Going ahead to step 3:
90 can be fit into 320 3 times, resulting in a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 270 away from 320, we end up with 50.
Bring next digit (4) of the dividend behind the 50 and repeat the process: 504 / 90

Advancing to step 4:
90 goes into 504 5 times with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 35.0
The remainder is 54 after subtracting 450 from 504.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 90

Moving on to step 5:
540 divided by 90 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 356.0
Subtract 540 from 540 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 90

On to step 6:
90 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 3560.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 90

Advancing to step 7:
90 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 35600.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 90

On to step 8:
When dividing 304 by 90, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 356003.0
If we subtract 270 from 304, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
340 divided by 90 is 3 with a remainder of 70.
Put 3 as the next digit of the answer. 
Result so far: 356003.3
The remainder is 70 after subtracting 270 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
700 divided by 90 is 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 356003.37
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
The number 90 fits into 700 7 times, leaving a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 356003.377
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 356003.377, with a leftover of 0.007.
