We look at the division of 392736 by 90 
We want to figure out the number of times 392736 can be divided by 90.

Going ahead to step 1:
3 divided by 90 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 90

On to step 2:
When dividing 39 by 90, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 90

Step 3:
392 divided by 90 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 360 from 392 to get 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 90

Step 4:
327 divided by 90 is 3 with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 270 away from 327, we end up with 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 90

Moving on to step 5:
573 divided by 90 is 6 with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
Subtract 540 from 573 to get 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 90

Moving on to step 6:
90 can be fit into 336 3 times, resulting in a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 4363.0
If we subtract 270 from 336, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 7:
When dividing 660 by 90, we get 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 4363.7
Deduct 630 from 660 and we're left 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.

Moving on to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 4363.73
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.

Step 9:
90 can be fit into 300 3 times, resulting in a remainder of 30.
The next digit of our result is 3. 
Result so far: 4363.733
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.

In conclusion, the division gives 4363.733 with a balance of 0.003.
