We look at the division of 521458 by 36 
The aim is to understand the frequency of 36 in 521458.

Moving on to step 1:
5 divided by 36 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 36

Advancing to step 2:
36 can be fit into 52 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 36 from 52 to get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 36

Moving on to step 3:
If we divide 161 by 36, we get 4 and a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 144 from 161 leaves us with 17.
Grab the next digit (4) from the dividend, add it to 17, then carry on: 174 / 36

Advancing to step 4:
If we divide 174 by 36, we get 4 and a remainder of 30.
The next digit of our result is 4. 
Result so far: 144.0
If we subtract 144 from 174, we get 30.
Fetch the next digit (5) from the dividend, attach it to 30 and continue: 305 / 36

On to step 5:
When dividing 305 by 36, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 1448.0
If we subtract 288 from 305, we get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 36

Let's proceed to step 6:
The number 36 fits into 178 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 14484.0
Deduct 144 from 178 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
36 can be fit into 340 9 times, resulting in a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 14484.9
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
The number 36 fits into 160 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 14484.94
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 36 fits into 160 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 14484.944
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 14484.944, and the remainder is 0.0016.
