We're dividing 36457 by 31 
The aim is to understand the frequency of 31 in 36457.

Going ahead to step 1:
The number 31 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 31

Moving on to step 2:
31 goes into 36 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 31 from 36 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 31

Advancing to step 3:
31 goes into 54 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 31 away from 54, we end up with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 31

Step 4:
31 can be fit into 235 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 117.0
The remainder is 18 after subtracting 217 from 235.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 31

On to step 5:
When dividing 187 by 31, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 1176.0
The remainder is 1 after subtracting 186 from 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
31 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1176.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
31 goes into 100 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 1176.03
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
If we divide 70 by 31, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1176.032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
31 goes into 80 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 1176.0322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 1176.0322 with a remainder of 0.00018.
