We're dividing 173 by 56 
The aim is to understand the frequency of 56 in 173.

Going ahead to step 1:
If we divide 1 by 56, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 56

Going ahead to step 2:
17 divided by 56 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 56

On to step 3:
56 can be fit into 173 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 168 from 173, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 4:
The number 56 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 5:
500 divided by 56 is 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 3.08
Deduct 448 from 500 and we're left 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.

Moving on to step 6:
56 can be fit into 520 9 times, resulting in a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 3.089
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 56 fits into 160 2 times, leaving a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 3.0892
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 8:
When dividing 480 by 56, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 3.08928
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.

On to step 9:
The number 56 fits into 320 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 3.089285
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.

Going ahead to step 10:
400 divided by 56 is 7 with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 3.0892857
Subtract 392 from 400 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 56, we get 1 and a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 3.08928571
If we subtract 56 from 80, we get 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 3.08928571 and a remainder of 2.4e-08.
