We're dividing 508521 by 56 
The aim is to understand the frequency of 56 in 508521.

Let's proceed to step 1:
When dividing 5 by 56, we get 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.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 56

Going ahead to step 2:
The number 56 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 56

On to step 3:
If we divide 508 by 56, we get 9 and a remainder of 4.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 504 from 508, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 56

Step 4:
If we divide 45 by 56, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
The remainder is 45 after subtracting 0 from 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 56

Let's proceed to step 5:
If we divide 452 by 56, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 908.0
Subtracting 448 from 452 leaves us with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 56

Going ahead to step 6:
41 divided by 56 is 0 with a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 9080.0
If we subtract 0 from 41, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
When dividing 410 by 56, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 9080.7
The remainder is 18 after subtracting 392 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
56 can be fit into 180 3 times, resulting in a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 9080.73
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 56 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 9080.732
Deduct 112 from 120 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.

Let's proceed to step 10:
If we divide 80 by 56, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 9080.7321
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.

Step 11:
240 divided by 56 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9080.73214
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
56 goes into 160 2 times with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 9080.732142
The remainder is 48 after subtracting 112 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
56 can be fit into 480 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 9080.7321428
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.

On to step 14:
If we divide 320 by 56, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 9080.73214285
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.

Our division results in 9080.73214285 with a remaining 4e-08.
