We look at the division of 746747 by 55 
The aim is to understand the frequency of 55 in 746747.

On to step 1:
55 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 55

Advancing to step 2:
If we divide 74 by 55, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 55 away from 74, we end up with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 55

On to step 3:
55 can be fit into 196 3 times, resulting in a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 165 from 196 and we're left with 31.
Fetch the next digit (7) from the dividend, attach it to 31 and continue: 317 / 55

Step 4:
55 can be fit into 317 5 times, resulting in a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Subtracting 275 from 317 leaves us with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 55

Moving on to step 5:
55 goes into 424 7 times with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 1357.0
The remainder is 39 after subtracting 385 from 424.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 55

On to step 6:
55 can be fit into 397 7 times, resulting in a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 13577.0
If we subtract 385 from 397, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 55 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 13577.2
The remainder is 10 after subtracting 110 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
55 can be fit into 100 1 times, resulting in a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 13577.21
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
If we divide 450 by 55, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 13577.218
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
100 divided by 55 is 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 13577.2181
The remainder is 45 after subtracting 55 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 13577.21818
If we take 440 away from 450, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 55, we get 1 and a remainder of 45.
The next digit of our result is 1. 
Result so far: 13577.218181
Deduct 55 from 100 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
The number 55 fits into 450 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 13577.2181818
If we take 440 away from 450, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
100 divided by 55 is 1 with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 13577.21818181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 13577.21818181 with a remainder of 4.5e-08.
