We're dividing 261278 by 36 
The aim is to understand the frequency of 36 in 261278.

On to step 1:
2 divided by 36 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 36

Let's proceed to step 2:
26 divided by 36 is 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Grab the next digit (1) from the dividend, add it to 26, then carry on: 261 / 36

Let's proceed to step 3:
36 goes into 261 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 9 after subtracting 252 from 261.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 36

On to step 4:
If we divide 92 by 36, we get 2 and a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 72 from 92 and we're left with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 36

Moving on to step 5:
The number 36 fits into 207 5 times, leaving a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 725.0
The remainder is 27 after subtracting 180 from 207.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 36

On to step 6:
If we divide 278 by 36, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 7257.0
The remainder is 26 after subtracting 252 from 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
When dividing 260 by 36, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 7257.7
Deduct 252 from 260 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.

On to step 8:
If we divide 80 by 36, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 7257.72
Subtract 72 from 80 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.

On to step 9:
If we divide 80 by 36, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 7257.722
If we subtract 72 from 80, we 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.

The final outcome is 7257.722, with a leftover of 0.0008.
