We're dividing 133136 by 1 
The aim is to understand the frequency of 1 in 133136.

Step 1:
1 divided by 1 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 1 from 1 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Moving on to step 2:
3 divided by 1 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 3 away from 3, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Advancing to step 3:
3 divided by 1 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 133.0
If we subtract 3 from 3, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Moving on to step 4:
If we divide 1 by 1, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1331.0
Subtracting 1 from 1 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Going ahead to step 5:
3 divided by 1 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 13313.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Going ahead to step 6:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 133136.0
If we subtract 6 from 6, 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.

Advancing to step 7:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 133136.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 133136.0
Subtract 0 from 0 to 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.

The quotient of the division is 133136.0, and the remainder is 0.0.
