We divide 20009604 by 90
Our goal is to divide 20009604 by 90.

Let's proceed to step 1:
90 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 90

On to step 2:
The number 90 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 90

Going ahead to step 3:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 20 after subtracting 180 from 200.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 90

Moving on to step 4:
When dividing 200 by 90, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 20 after subtracting 180 from 200.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 90

Moving on to step 5:
When dividing 209 by 90, we get 2 with a remainder of 29.
The next digit of our result is 2. 
Result so far: 222.0
If we take 180 away from 209, we end up with 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 90

Step 6:
The number 90 fits into 296 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 2223.0
If we subtract 270 from 296, we get 26.
Fetch the next digit (0) from the dividend, attach it to 26 and continue: 260 / 90

Advancing to step 7:
When dividing 260 by 90, we get 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 22232.0
The remainder is 80 after subtracting 180 from 260.
Fetch the next digit (4) from the dividend, attach it to 80 and continue: 804 / 90

Step 8:
The number 90 fits into 804 8 times, leaving a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 222328.0
If we subtract 720 from 804, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
If we divide 840 by 90, we get 9 and a remainder of 30.
Write down 9 as next digit of the result. 
Result so far: 222328.9
Subtracting 810 from 840 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.

Let's proceed to step 10:
90 goes into 300 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 222328.93
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.

On to step 11:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 222328.933
If we take 270 away from 300, we end up 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 222328.933 with a balance of 0.003.
