We divide 613603 by 36
The aim is to understand the frequency of 36 in 613603.

Let's proceed to step 1:
If we divide 6 by 36, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 36

Advancing to step 2:
36 goes into 61 1 times with a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 36 from 61 to get 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 36

Going ahead to step 3:
When dividing 253 by 36, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 1 after subtracting 252 from 253.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 36

Step 4:
36 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtract 0 from 16 to get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 36

Going ahead to step 5:
36 can be fit into 160 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1704.0
If we take 144 away from 160, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 36

On to step 6:
36 can be fit into 163 4 times, resulting in a remainder of 19.
The next digit of our result is 4. 
Result so far: 17044.0
The remainder is 19 after subtracting 144 from 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
36 can be fit into 190 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 17044.5
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 36, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 17044.52
Subtract 72 from 100 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
36 can be fit into 280 7 times, resulting in a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 17044.527
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 10:
36 can be fit into 280 7 times, resulting in a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 17044.5277
If we take 252 away from 280, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 17044.5277 with a remaining 0.00028.
