Let's divide 621966 by 36
The aim is to understand the frequency of 36 in 621966.

Let's proceed to step 1:
When dividing 6 by 36, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 36

On to step 2:
62 divided by 36 is 1 with a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 36 from 62 leaves us with 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 36

Let's proceed to step 3:
36 can be fit into 261 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 252 from 261 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 36

Advancing to step 4:
The number 36 fits into 99 2 times, leaving a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 172.0
Subtracting 72 from 99 leaves us with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 36

On to step 5:
276 divided by 36 is 7 with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 1727.0
If we subtract 252 from 276, we get 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 36

On to step 6:
36 goes into 246 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 17276.0
If we take 216 away from 246, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
36 goes into 300 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 17276.8
If we take 288 away from 300, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
When dividing 120 by 36, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 17276.83
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 36, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 17276.833
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 17276.833 with a remainder of 0.0012.
