520117 ÷ 55 
The aim is to understand the frequency of 55 in 520117.

Step 1:
55 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 55

Going ahead to step 2:
55 goes into 52 0 times with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 55

Going ahead to step 3:
When dividing 520 by 55, we get 9 with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 495 from 520, we get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 55

On to step 4:
If we divide 251 by 55, we get 4 and a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 220 away from 251, we end up with 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 55

Step 5:
55 can be fit into 311 5 times, resulting in a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 945.0
The remainder is 36 after subtracting 275 from 311.
Take the next digit (7) from the dividend and append it to 36, then repeat: 367 / 55

Step 6:
55 can be fit into 367 6 times, resulting in a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 9456.0
The remainder is 37 after subtracting 330 from 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
The number 55 fits into 370 6 times, leaving a remainder of 40.
The next digit of our result is 6. 
Result so far: 9456.6
Subtract 330 from 370 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 8:
When dividing 400 by 55, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 9456.67
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.

Moving on to step 9:
55 goes into 150 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 9456.672
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.

Step 10:
If we divide 400 by 55, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 9456.6727
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 11:
The number 55 fits into 150 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 9456.67272
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.

Let's proceed to step 12:
When dividing 400 by 55, we get 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 9456.672727
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.

Advancing to step 13:
150 divided by 55 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 9456.6727272
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.

Step 14:
55 goes into 400 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 9456.67272727
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.

The final outcome is 9456.67272727, with a leftover of 1.5e-08.
