403343 divided by 56 
The aim is to understand the frequency of 56 in 403343.

On to step 1:
4 divided by 56 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 56

Let's proceed to step 2:
40 divided by 56 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 56

Let's proceed to step 3:
56 goes into 403 7 times with a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 392 away from 403, we end up with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 56

Advancing to step 4:
If we divide 113 by 56, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Deduct 112 from 113 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 56

On to step 5:
56 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 720.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 56

Let's proceed to step 6:
56 can be fit into 143 2 times, resulting in a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 7202.0
Subtract 112 from 143 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
56 goes into 310 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7202.5
Subtract 280 from 310 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
56 can be fit into 300 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 7202.55
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 7202.55, with a leftover of 0.02.
