645966 divided by 36 
The aim is to understand the frequency of 36 in 645966.

Going ahead to step 1:
When dividing 6 by 36, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 36

Moving on to step 2:
64 divided by 36 is 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 36 from 64 to get 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 36

Advancing to step 3:
285 divided by 36 is 7 with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 252 from 285, we get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 36

Moving on to step 4:
339 divided by 36 is 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Subtracting 324 from 339 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 36

Advancing to step 5:
156 divided by 36 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 1794.0
Subtract 144 from 156 to get 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 36

Step 6:
When dividing 126 by 36, we get 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 17943.0
Subtract 108 from 126 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
36 goes into 180 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 17943.5
Subtract 180 from 180 to 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.

Advancing to step 8:
When dividing 0 by 36, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17943.5
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.

Advancing to step 9:
If we divide 0 by 36, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 17943.5
If we take 0 away from 0, we end up 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.

The quotient of the division is 17943.5, and the remainder is 0.0.
