We're dividing 742122 by 55 
The aim is to understand the frequency of 55 in 742122.

On to step 1:
If we divide 7 by 55, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 55

Advancing to step 2:
74 divided by 55 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 55 from 74 to get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 55

Step 3:
192 divided by 55 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 165 from 192 and we're left with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 55

Step 4:
The number 55 fits into 271 4 times, leaving a remainder of 51.
The next digit of our result is 4. 
Result so far: 134.0
Subtracting 220 from 271 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 55

Moving on to step 5:
55 goes into 512 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 1349.0
If we take 495 away from 512, we end up with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 55

Advancing to step 6:
55 can be fit into 172 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 13493.0
Deduct 165 from 172 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
55 can be fit into 70 1 times, resulting in a remainder of 15.
The next digit of our result is 1. 
Result so far: 13493.1
Deduct 55 from 70 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
When dividing 150 by 55, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 13493.12
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 55 fits into 400 7 times, leaving a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 13493.127
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
150 divided by 55 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 13493.1272
Subtract 110 from 150 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
55 goes into 400 7 times with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 13493.12727
The remainder is 15 after subtracting 385 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
55 goes into 150 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 13493.127272
If we take 110 away from 150, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
When dividing 400 by 55, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 13493.1272727
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 14:
If we divide 150 by 55, we get 2 and a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 13493.12727272
The remainder is 40 after subtracting 110 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 13493.12727272, with a leftover of 4e-08.
