We look at the division of 591437 by 56 
The aim is to understand the frequency of 56 in 591437.

Going ahead to step 1:
5 divided by 56 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 56

On to step 2:
When dividing 59 by 56, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 56 from 59.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 56

Moving on to step 3:
The number 56 fits into 31 0 times, leaving a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 31, we end up with 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 56

Advancing to step 4:
If we divide 314 by 56, we get 5 and a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 105.0
The remainder is 34 after subtracting 280 from 314.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 56

Advancing to step 5:
56 can be fit into 343 6 times, resulting in a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 1056.0
If we subtract 336 from 343, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 56

Going ahead to step 6:
The number 56 fits into 77 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 10561.0
If we subtract 56 from 77, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
56 goes into 210 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 10561.3
If we take 168 away from 210, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
When dividing 420 by 56, we get 7 with a remainder of 28.
The next digit of our result is 7. 
Result so far: 10561.37
If we take 392 away from 420, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
When dividing 280 by 56, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10561.375
The remainder is 0 after subtracting 280 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 56 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10561.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
56 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10561.375
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 10561.375 with a remainder of 0.0.
