We look at the division of 439410 by 55 
The aim is to understand the frequency of 55 in 439410.

On to step 1:
When dividing 4 by 55, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 55

Step 2:
43 divided by 55 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 55

Advancing to step 3:
55 goes into 439 7 times with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 385 from 439 leaves us with 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 55

Step 4:
544 divided by 55 is 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 495 from 544 and we're left with 49.
Grab the next digit (1) from the dividend, add it to 49, then carry on: 491 / 55

Step 5:
491 divided by 55 is 8 with a remainder of 51.
Put 8 as the next digit of the answer. 
Result so far: 798.0
Deduct 440 from 491 and we're left with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 55

Moving on to step 6:
55 can be fit into 510 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 7989.0
Subtract 495 from 510 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.

Let's proceed to step 7:
55 goes into 150 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 7989.2
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.

Advancing to step 8:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 7989.27
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.

Let's proceed to step 9:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 7989.272
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.

Step 10:
400 divided by 55 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 7989.2727
If we subtract 385 from 400, we 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.

Moving on to step 11:
55 goes into 150 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7989.27272
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 12:
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: 7989.272727
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.

Let's proceed to step 13:
150 divided by 55 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 7989.2727272
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.

Advancing to step 14:
When dividing 400 by 55, we get 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 7989.27272727
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.

The final result is 7989.27272727 with a remainder of 1.5e-08.
