Let's divide 973721 by 90
Our goal is to divide 973721 by 90.

Advancing to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 90

On to step 2:
When dividing 97 by 90, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 90 from 97 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 90

Moving on to step 3:
If we divide 73 by 90, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 90

On to step 4:
90 goes into 737 8 times with a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Deduct 720 from 737 and we're left with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 90

Going ahead to step 5:
The number 90 fits into 172 1 times, leaving a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 1081.0
Subtract 90 from 172 to get 82.
Fetch the next digit (1) from the dividend, attach it to 82 and continue: 821 / 90

Advancing to step 6:
90 goes into 821 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 10819.0
The remainder is 11 after subtracting 810 from 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
90 goes into 110 1 times with a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 10819.1
Deduct 90 from 110 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 10819.12
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 90, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 10819.122
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 10819.122 and a remainder of 0.002.
