603587 ÷ 36 
The aim is to understand the frequency of 36 in 603587.

Advancing to step 1:
36 can be fit into 6 0 times, resulting in 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.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 36

Moving on to step 2:
The number 36 fits into 60 1 times, leaving a remainder of 24.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 36 from 60 and we're left with 24.
Grab the next digit (3) from the dividend, add it to 24, then carry on: 243 / 36

Let's proceed to step 3:
243 divided by 36 is 6 with a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 216 from 243 leaves us with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 36

Step 4:
36 goes into 275 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 167.0
Subtract 252 from 275 to get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 36

Advancing to step 5:
If we divide 238 by 36, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 1676.0
If we take 216 away from 238, we end up with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 36

On to step 6:
The number 36 fits into 227 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 16766.0
If we take 216 away from 227, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
110 divided by 36 is 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 16766.3
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
20 divided by 36 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 16766.3
If we take 0 away from 20, 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.

Let's proceed to step 9:
When dividing 200 by 36, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 16766.305
If we subtract 180 from 200, we 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 10:
The number 36 fits into 200 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 16766.3055
Deduct 180 from 200 and we're left 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 16766.3055 with a remainder of 0.0002.
