Let's divide 171515 by 36
The aim is to understand the frequency of 36 in 171515.

On to step 1:
36 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 36

On to step 2:
The number 36 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 36

Moving on to step 3:
36 can be fit into 171 4 times, resulting in a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 144 from 171, we get 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 36

Moving on to step 4:
275 divided by 36 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 47.0
Deduct 252 from 275 and we're left with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 36

Advancing to step 5:
If we divide 231 by 36, we get 6 and a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 476.0
If we take 216 away from 231, we end up with 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 36

On to step 6:
When dividing 155 by 36, we get 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4764.0
Subtract 144 from 155 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
When dividing 110 by 36, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 4764.3
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
36 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4764.3
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 36 fits into 200 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 4764.305
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
36 goes into 200 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 4764.3055
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 4764.3055 and a remainder of 0.0002.
