We look at the division of 171213 by 36 
The aim is to understand the frequency of 36 in 171213.

Moving on to step 1:
1 divided by 36 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 36

Step 2:
36 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 36

Let's proceed to step 3:
36 goes into 171 4 times with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 27 after subtracting 144 from 171.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 36

Going ahead to step 4:
When dividing 272 by 36, we get 7 with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 47.0
The remainder is 20 after subtracting 252 from 272.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 36

Moving on to step 5:
If we divide 201 by 36, we get 5 and a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 475.0
Subtracting 180 from 201 leaves us with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 36

Moving on to step 6:
If we divide 213 by 36, we get 5 and a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 4755.0
Subtracting 180 from 213 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
The number 36 fits into 330 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 4755.9
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
36 goes into 60 1 times with a remainder of 24.
The next digit of our result is 1. 
Result so far: 4755.91
Deduct 36 from 60 and we're left 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.

Advancing to step 9:
240 divided by 36 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 4755.916
If we take 216 away from 240, we end up 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 10:
The number 36 fits into 240 6 times, leaving a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 4755.9166
If we take 216 away from 240, we end up 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.

The final result is 4755.9166 with a remainder of 0.00024.
