We look at the division of 392202 by 90 
We want to divide 392202 by 90.

Advancing to step 1:
90 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 90

Moving on to step 2:
90 can be fit into 39 0 times, resulting in a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 90

Moving on to step 3:
When dividing 392 by 90, we get 4 with a remainder of 32.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 360 from 392 and we're left with 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 90

Let's proceed to step 4:
The number 90 fits into 322 3 times, leaving a remainder of 52.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 270 from 322 and we're left with 52.
Bring next digit (0) of the dividend behind the 52 and repeat the process: 520 / 90

Moving on to step 5:
90 can be fit into 520 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 435.0
Subtract 450 from 520 to get 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 90

Step 6:
90 can be fit into 702 7 times, resulting in a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 4357.0
If we take 630 away from 702, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
90 can be fit into 720 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 4357.8
Subtracting 720 from 720 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 90 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4357.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4357.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 4357.8, with a leftover of 0.0.
