We're dividing 721317 by 56 
The aim is to understand the frequency of 56 in 721317.

On to step 1:
When dividing 7 by 56, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 56

On to step 2:
56 goes into 72 1 times with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 56 from 72 and we're left with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 56

Going ahead to step 3:
When dividing 161 by 56, we get 2 with a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 112 from 161 to get 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 56

Advancing to step 4:
If we divide 493 by 56, we get 8 and a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
The remainder is 45 after subtracting 448 from 493.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 56

Step 5:
The number 56 fits into 451 8 times, leaving a remainder of 3.
The next digit of our result is 8. 
Result so far: 1288.0
The remainder is 3 after subtracting 448 from 451.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 56

Let's proceed to step 6:
56 goes into 37 0 times with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 12880.0
Subtracting 0 from 37 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
56 can be fit into 370 6 times, resulting in a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 12880.6
The remainder is 34 after subtracting 336 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
If we divide 340 by 56, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12880.66
Subtracting 336 from 340 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.

Our division results in 12880.66 with a remaining 0.004.
