We're dividing 350813 by 36 
The aim is to understand the frequency of 36 in 350813.

Step 1:
When dividing 3 by 36, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 36

Step 2:
36 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 36

Advancing to step 3:
The number 36 fits into 350 9 times, leaving a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 324 from 350 and we're left with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 36

Going ahead to step 4:
When dividing 268 by 36, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtract 252 from 268 to get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 36

On to step 5:
161 divided by 36 is 4 with a remainder of 17.
The next digit of our result is 4. 
Result so far: 974.0
The remainder is 17 after subtracting 144 from 161.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 36

Step 6:
36 goes into 173 4 times with a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 9744.0
Subtracting 144 from 173 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
290 divided by 36 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 9744.8
Deduct 288 from 290 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 36, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9744.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 36 fits into 200 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 9744.805
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 36 fits into 200 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 9744.8055
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 9744.8055 with a remainder of 0.0002.
