We're dividing 56238 by 15 
The aim is to understand the frequency of 15 in 56238.

On to step 1:
If we divide 5 by 15, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 15

Step 2:
15 can be fit into 56 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 45 from 56 to get 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 15

Advancing to step 3:
If we divide 112 by 15, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
If we subtract 105 from 112, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 15

Advancing to step 4:
15 can be fit into 73 4 times, resulting in a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 374.0
Subtract 60 from 73 to get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 15

Moving on to step 5:
138 divided by 15 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 3749.0
Deduct 135 from 138 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
When dividing 30 by 15, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 3749.2
Deduct 30 from 30 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.

Going ahead to step 7:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3749.2
Subtracting 0 from 0 leaves us 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.

Step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3749.2
If we subtract 0 from 0, we 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.

The quotient of the division is 3749.2, and the remainder is 0.0.
