Let's divide 9990 by 22
We're looking to find how many times 22 goes into 9990.

On to step 1:
9 divided by 22 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 22

Advancing to step 2:
The number 22 fits into 99 4 times, leaving a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 88 from 99 to get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 22

Moving on to step 3:
22 can be fit into 119 5 times, resulting in a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we take 110 away from 119, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 22

Let's proceed to step 4:
If we divide 90 by 22, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 454.0
Deduct 88 from 90 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 5:
The number 22 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 454.0
Subtracting 0 from 20 leaves us 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.

Advancing to step 6:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 454.09
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 22 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 454.09
Subtracting 0 from 20 leaves us 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.

On to step 8:
200 divided by 22 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 454.0909
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
22 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 454.0909
If we take 0 away from 20, we end up 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.

Advancing to step 10:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 454.090909
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
22 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 454.090909
The remainder is 20 after subtracting 0 from 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 12:
200 divided by 22 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 454.09090909
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 454.09090909 with a remainder of 2e-09.
