We're dividing 728424 by 55 
The aim is to understand the frequency of 55 in 728424.

Going ahead to step 1:
The number 55 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 55

Let's proceed to step 2:
If we divide 72 by 55, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 55 from 72 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 55

Let's proceed to step 3:
When dividing 178 by 55, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 13 after subtracting 165 from 178.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 55

Let's proceed to step 4:
55 goes into 134 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 132.0
The remainder is 24 after subtracting 110 from 134.
Append the next digit (2) from the dividend to 24 and continue with: 242 / 55

Let's proceed to step 5:
If we divide 242 by 55, we get 4 and a remainder of 22.
The next digit of our result is 4. 
Result so far: 1324.0
The remainder is 22 after subtracting 220 from 242.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 55

Let's proceed to step 6:
If we divide 224 by 55, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 13244.0
Subtracting 220 from 224 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
55 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 13244.0
Deduct 0 from 40 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.

Let's proceed 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: 13244.07
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.

Going ahead to step 9:
55 can be fit into 150 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 13244.072
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.

Advancing to 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: 13244.0727
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.

Advancing to step 11:
The number 55 fits into 150 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 13244.07272
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.

Advancing to step 12:
55 can be fit into 400 7 times, resulting in a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 13244.072727
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 13:
When dividing 150 by 55, we get 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 13244.0727272
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 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: 13244.07272727
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.

In conclusion, the division gives 13244.07272727 with a balance of 1.5e-08.
