690144 ÷ 36 
The aim is to understand the frequency of 36 in 690144.

On to step 1:
The number 36 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 36

Advancing to step 2:
If we divide 69 by 36, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 33 after subtracting 36 from 69.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 36

On to step 3:
If we divide 330 by 36, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 324 from 330 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 36

Step 4:
If we divide 61 by 36, we get 1 and a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 191.0
If we subtract 36 from 61, we get 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 36

Advancing to step 5:
The number 36 fits into 254 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 1917.0
Subtracting 252 from 254 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 36

Going ahead to step 6:
24 divided by 36 is 0 with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 19170.0
Subtract 0 from 24 to 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.

Step 7:
36 can be fit into 240 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 19170.6
Subtract 216 from 240 to 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.

Moving on to step 8:
240 divided by 36 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 19170.66
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.

Our division results in 19170.66 with a remaining 0.024.
