We look at the division of 780366 by 55 
The aim is to understand the frequency of 55 in 780366.

Let's proceed to step 1:
55 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 55

Going ahead to step 2:
55 can be fit into 78 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 55 from 78 and we're left with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 55

Advancing to step 3:
55 goes into 230 4 times with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 220 from 230 leaves us with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 55

Step 4:
If we divide 103 by 55, we get 1 and a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
If we take 55 away from 103, we end up with 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 55

Advancing to step 5:
The number 55 fits into 486 8 times, leaving a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 1418.0
Subtract 440 from 486 to get 46.
Take the next digit (6) from the dividend and append it to 46, then repeat: 466 / 55

Moving on to step 6:
55 goes into 466 8 times with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 14188.0
If we take 440 away from 466, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
260 divided by 55 is 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 14188.4
Subtract 220 from 260 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 8:
The number 55 fits into 400 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 14188.47
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.

Advancing to step 9:
55 goes into 150 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 14188.472
If we subtract 110 from 150, we 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.

Step 10:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 14188.4727
Subtracting 385 from 400 leaves us 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 11:
150 divided by 55 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 14188.47272
Subtracting 110 from 150 leaves us 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 12:
The number 55 fits into 400 7 times, leaving a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 14188.472727
Deduct 385 from 400 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.

Going ahead to step 13:
When dividing 150 by 55, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 14188.4727272
If we subtract 110 from 150, we 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.

Advancing to step 14:
The number 55 fits into 400 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 14188.47272727
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 14188.47272727 and a remainder of 1.5e-08.
