We look at the division of 102155 by 56 
The aim is to understand the frequency of 56 in 102155.

On to step 1:
If we divide 1 by 56, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 56

Going ahead to step 2:
The number 56 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 56

Moving on to step 3:
If we divide 102 by 56, we get 1 and a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 56 from 102 and we're left with 46.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 56

On to step 4:
When dividing 461 by 56, we get 8 with a remainder of 13.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 448 from 461 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 56

Step 5:
The number 56 fits into 135 2 times, leaving a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 182.0
The remainder is 23 after subtracting 112 from 135.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 56

Advancing to step 6:
When dividing 235 by 56, we get 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 1824.0
Subtracting 224 from 235 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 56, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1824.1
The remainder is 54 after subtracting 56 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
When dividing 540 by 56, we get 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 1824.19
Subtract 504 from 540 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
56 can be fit into 360 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1824.196
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
240 divided by 56 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1824.1964
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 56 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 1824.19642
Subtract 112 from 160 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
If we divide 480 by 56, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 1824.196428
If we take 448 away from 480, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
The number 56 fits into 320 5 times, leaving a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 1824.1964285
The remainder is 40 after subtracting 280 from 320.
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:
If we divide 400 by 56, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 1824.19642857
Subtracting 392 from 400 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1824.19642857 with a remaining 8e-09.
