81833373 divided by 36 
The aim is to understand the frequency of 36 in 81833373.

Step 1:
The number 36 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 36

Going ahead to step 2:
The number 36 fits into 81 2 times, leaving a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 9 after subtracting 72 from 81.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 36

Advancing to step 3:
If we divide 98 by 36, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 26 after subtracting 72 from 98.
Fetch the next digit (3) from the dividend, attach it to 26 and continue: 263 / 36

Advancing to step 4:
The number 36 fits into 263 7 times, leaving a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 227.0
The remainder is 11 after subtracting 252 from 263.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 36

Going ahead to step 5:
When dividing 113 by 36, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 2273.0
Subtracting 108 from 113 leaves us with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 36

Going ahead to step 6:
When dividing 53 by 36, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 22731.0
The remainder is 17 after subtracting 36 from 53.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 36

Let's proceed to step 7:
177 divided by 36 is 4 with a remainder of 33.
The next digit of our result is 4. 
Result so far: 227314.0
If we take 144 away from 177, we end up with 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 36

Advancing to step 8:
The number 36 fits into 333 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 2273149.0
The remainder is 9 after subtracting 324 from 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
36 can be fit into 90 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 2273149.2
Deduct 72 from 90 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
When dividing 180 by 36, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2273149.25
Deduct 180 from 180 and we're left 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.

On to step 11:
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: 2273149.25
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.

Let's proceed to step 12:
36 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2273149.25
If we subtract 0 from 0, we 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.

Our division results in 2273149.25 with a remaining 0.0.
