12872 divided by 56 
The aim is to understand the frequency of 56 in 12872.

Step 1:
If we divide 1 by 56, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 56

Let's proceed to step 2:
If we divide 12 by 56, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 56

Going ahead to step 3:
128 divided by 56 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 112 from 128 leaves us with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 56

Advancing to step 4:
When dividing 167 by 56, we get 2 with a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 112 from 167, we get 55.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 56

On to step 5:
If we divide 552 by 56, we get 9 and a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
Subtracting 504 from 552 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 6:
When dividing 480 by 56, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 229.8
Subtracting 448 from 480 leaves us 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.

Advancing to step 7:
When dividing 320 by 56, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 229.85
If we take 280 away from 320, 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.

On to step 8:
400 divided by 56 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 229.857
The remainder is 8 after subtracting 392 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 56 fits into 80 1 times, leaving a remainder of 24.
The next digit of our result is 1. 
Result so far: 229.8571
If we take 56 away from 80, we end up 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.

Step 10:
240 divided by 56 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 229.85714
Deduct 224 from 240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
If we divide 160 by 56, we get 2 and a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 229.857142
Deduct 112 from 160 and we're left with 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:
56 goes into 480 8 times with a remainder of 32.
The next digit of our result is 8. 
Result so far: 229.8571428
Subtract 448 from 480 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
When dividing 320 by 56, we get 5 with a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 229.85714285
Deduct 280 from 320 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.

Our division results in 229.85714285 with a remaining 4e-08.
