Let's divide 220170 by 55
The aim is to understand the frequency of 55 in 220170.

Step 1:
2 divided by 55 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 55

On to step 2:
When dividing 22 by 55, we get 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 55

Advancing to step 3:
55 can be fit into 220 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 220 away from 220, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 55

Step 4:
55 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 55

On to step 5:
When dividing 17 by 55, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
If we subtract 0 from 17, we get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 55

Moving on to step 6:
55 can be fit into 170 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 4003.0
If we subtract 165 from 170, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 55 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4003.0
If we take 0 away from 50, we end up 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.

Advancing to step 8:
When dividing 500 by 55, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 4003.09
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
If we divide 50 by 55, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 4003.09
If we subtract 0 from 50, 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.

Advancing to step 10:
The number 55 fits into 500 9 times, leaving a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 4003.0909
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
If we divide 50 by 55, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 4003.0909
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
If we divide 500 by 55, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 4003.090909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
55 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 4003.090909
Deduct 0 from 50 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 14:
The number 55 fits into 500 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 4003.09090909
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 4003.09090909, with a leftover of 5e-09.
