We look at the division of 864813 by 56 
The aim is to understand the frequency of 56 in 864813.

On to step 1:
The number 56 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 56

Step 2:
86 divided by 56 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 56 from 86 leaves us with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 56

Going ahead to step 3:
304 divided by 56 is 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 280 from 304, we get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 56

Moving on to step 4:
If we divide 248 by 56, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtract 224 from 248 to get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 56

Step 5:
241 divided by 56 is 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 1544.0
Subtract 224 from 241 to get 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 56

Going ahead to step 6:
The number 56 fits into 173 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 15443.0
Subtracting 168 from 173 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
56 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 15443.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
56 goes into 500 8 times with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 15443.08
Subtracting 448 from 500 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
520 divided by 56 is 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 15443.089
Subtracting 504 from 520 leaves us 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.

Moving on to step 10:
When dividing 160 by 56, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 15443.0892
If we take 112 away from 160, we end up 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 11:
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: 15443.08928
The remainder is 32 after subtracting 448 from 480.
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 12:
56 goes into 320 5 times with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 15443.089285
Subtracting 280 from 320 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 13:
The number 56 fits into 400 7 times, leaving a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 15443.0892857
Deduct 392 from 400 and we're left 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.

Moving on to step 14:
80 divided by 56 is 1 with a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 15443.08928571
Subtracting 56 from 80 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.

After the division, we end up with 15443.08928571 and a remainder of 2.4e-08.
