We divide 457508 by 31
The aim is to understand the frequency of 31 in 457508.

Step 1:
4 divided by 31 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 31

On to step 2:
When dividing 45 by 31, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 31 from 45 leaves us with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 31

Moving on to step 3:
The number 31 fits into 147 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 23 after subtracting 124 from 147.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 31

Step 4:
When dividing 235 by 31, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
Subtract 217 from 235 to get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 31

Going ahead to step 5:
If we divide 180 by 31, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 1475.0
Subtracting 155 from 180 leaves us with 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 31

On to step 6:
If we divide 258 by 31, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 14758.0
Deduct 248 from 258 and we're left with 10.
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 7:
100 divided by 31 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 14758.3
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
When dividing 70 by 31, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 14758.32
Deduct 62 from 70 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 14758.322
Deduct 62 from 80 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 14758.322 with a remaining 0.0018.
