667721 divided by 36 
The aim is to understand the frequency of 36 in 667721.

Step 1:
6 divided by 36 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 36

Step 2:
If we divide 66 by 36, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 36 from 66, we get 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 36

Step 3:
36 goes into 307 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 288 from 307, we get 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 36

Step 4:
36 goes into 197 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 185.0
Subtracting 180 from 197 leaves us with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 36

On to step 5:
If we divide 172 by 36, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 1854.0
Subtract 144 from 172 to get 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 36

Advancing to step 6:
36 can be fit into 281 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 18547.0
Deduct 252 from 281 and we're left 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.

On to step 7:
When dividing 290 by 36, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 18547.8
The remainder is 2 after subtracting 288 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
36 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 18547.8
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.

Let's proceed to step 9:
200 divided by 36 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 18547.805
Subtracting 180 from 200 leaves us 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.

Step 10:
36 can be fit into 200 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 18547.8055
Subtracting 180 from 200 leaves us 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.

Our division results in 18547.8055 with a remaining 0.0002.
