Let's divide 397632 by 90
We want to figure out the number of times 397632 can be divided by 90.

Advancing to step 1:
When dividing 3 by 90, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 90

Step 2:
The number 90 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 90

Step 3:
If we divide 397 by 90, we get 4 and a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 360 from 397 to get 37.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 90

On to step 4:
If we divide 376 by 90, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 360 from 376 leaves us with 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 90

Let's proceed to step 5:
163 divided by 90 is 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 441.0
Subtract 90 from 163 to get 73.
Append the next digit (2) from the dividend to 73 and continue with: 732 / 90

On to step 6:
If we divide 732 by 90, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 4418.0
The remainder is 12 after subtracting 720 from 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
90 goes into 120 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 4418.1
Subtracting 90 from 120 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 90 fits into 300 3 times, leaving a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 4418.13
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
If we divide 300 by 90, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 4418.133
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 4418.133, and the remainder is 0.003.
