We divide 220172 by 90
The aim is to understand the frequency of 90 in 220172.

Going ahead to step 1:
90 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 90

Going ahead to step 2:
90 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 90

Moving on to step 3:
90 goes into 220 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 180 away from 220, we end up with 40.
Bring next digit (1) of the dividend behind the 40 and repeat the process: 401 / 90

On to step 4:
90 can be fit into 401 4 times, resulting in a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 360 from 401 leaves us with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 90

Let's proceed to step 5:
When dividing 417 by 90, we get 4 with a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 244.0
If we subtract 360 from 417, we get 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 90

Going ahead to step 6:
90 can be fit into 572 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 2446.0
Subtract 540 from 572 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
If we divide 320 by 90, we get 3 and a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 2446.3
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 90 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 2446.35
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2446.355
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 2446.355 with a balance of 0.005.
