Let's divide 373218 by 90
Our goal is to divide 373218 by 90.

Step 1:
90 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 90

Moving on to step 2:
The number 90 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 37 after subtracting 0 from 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 90

Advancing to step 3:
When dividing 373 by 90, we get 4 with a remainder of 13.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 360 from 373 and we're left with 13.
Fetch the next digit (2) from the dividend, attach it to 13 and continue: 132 / 90

On to step 4:
The number 90 fits into 132 1 times, leaving a remainder of 42.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 90 from 132 leaves us with 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 90

Let's proceed to step 5:
90 goes into 421 4 times with a remainder of 61.
The next digit of our result is 4. 
Result so far: 414.0
Subtracting 360 from 421 leaves us with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 90

Going ahead to step 6:
If we divide 618 by 90, we get 6 and a remainder of 78.
Write down 6 as next digit of the result. 
Result so far: 4146.0
The remainder is 78 after subtracting 540 from 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 7:
780 divided by 90 is 8 with a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 4146.8
Subtracting 720 from 780 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
The number 90 fits into 600 6 times, leaving a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4146.86
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The next digit of our result is 6. 
Result so far: 4146.866
The remainder is 60 after subtracting 540 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 4146.866 with a balance of 0.006.
