We're dividing 43212 by 55 
The aim is to understand the frequency of 55 in 43212.

Let's proceed to step 1:
55 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 55

Step 2:
43 divided by 55 is 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 55

Going ahead to step 3:
If we divide 432 by 55, we get 7 and a remainder of 47.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 385 from 432 leaves us with 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 55

Going ahead to step 4:
When dividing 471 by 55, we get 8 with a remainder of 31.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
The remainder is 31 after subtracting 440 from 471.
Take the next digit (2) from the dividend and append it to 31, then repeat: 312 / 55

Let's proceed to step 5:
If we divide 312 by 55, we get 5 and a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 785.0
If we take 275 away from 312, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 6:
The number 55 fits into 370 6 times, leaving a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 785.6
Deduct 330 from 370 and we're left 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.

On to step 7:
400 divided by 55 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 785.67
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.

On to step 8:
55 goes into 150 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 785.672
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.

Going ahead to step 9:
If we divide 400 by 55, we get 7 and a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 785.6727
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 10:
If we divide 150 by 55, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 785.67272
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.

Going ahead to step 11:
400 divided by 55 is 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 785.672727
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.

On to step 12:
150 divided by 55 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 785.6727272
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.

Going ahead to step 13:
If we divide 400 by 55, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 785.67272727
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.

Our division results in 785.67272727 with a remaining 1.5e-08.
