Let's divide 693120 by 55
The aim is to understand the frequency of 55 in 693120.

On to step 1:
The number 55 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 55

On to step 2:
If we divide 69 by 55, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 55 from 69 leaves us with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 55

Moving on to step 3:
If we divide 143 by 55, we get 2 and a remainder of 33.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 110 from 143 leaves us with 33.
Fetch the next digit (1) from the dividend, attach it to 33 and continue: 331 / 55

Advancing to step 4:
55 can be fit into 331 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 126.0
The remainder is 1 after subtracting 330 from 331.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 55

Advancing to step 5:
55 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 1260.0
Subtract 0 from 12 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 55

Let's proceed to step 6:
120 divided by 55 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 12602.0
If we take 110 away from 120, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 55, we get 1 with a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 12602.1
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
450 divided by 55 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 12602.18
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
55 can be fit into 100 1 times, resulting in a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 12602.181
If we take 55 away from 100, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
When dividing 450 by 55, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 12602.1818
Subtract 440 from 450 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
55 goes into 100 1 times with a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 12602.18181
If we subtract 55 from 100, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
450 divided by 55 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 12602.181818
The remainder is 10 after subtracting 440 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
100 divided by 55 is 1 with a remainder of 45.
The next digit of our result is 1. 
Result so far: 12602.1818181
Subtract 55 from 100 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
The number 55 fits into 450 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 12602.18181818
Subtracting 440 from 450 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 12602.18181818 with a remaining 1e-08.
