We look at the division of 99090 by 22 
The aim is to understand the frequency of 22 in 99090.

Moving on to step 1:
22 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 22

Going ahead to step 2:
99 divided by 22 is 4 with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 88 from 99 and we're left with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 22

Advancing to step 3:
22 can be fit into 110 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 110 from 110 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 22

On to step 4:
If we divide 9 by 22, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 450.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 22

Advancing to step 5:
22 goes into 90 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4504.0
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.

Moving on to step 6:
22 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 4504.0
Subtract 0 from 20 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.

Advancing to step 7:
22 goes into 200 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 4504.09
If we take 198 away from 200, we end up 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.

Going ahead to step 8:
22 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4504.09
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.

Moving on to step 9:
22 can be fit into 200 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 4504.0909
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 10:
If we divide 20 by 22, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4504.0909
Deduct 0 from 20 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.

Advancing to step 11:
200 divided by 22 is 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 4504.090909
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.

Advancing to step 12:
22 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 4504.090909
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.

Going ahead to step 13:
22 can be fit into 200 9 times, resulting in a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 4504.09090909
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.

After the division, we end up with 4504.09090909 and a remainder of 2e-09.
