283426 divided by 31 
The aim is to understand the frequency of 31 in 283426.

Step 1:
When dividing 2 by 31, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 31

Advancing to step 2:
31 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 31

Going ahead to step 3:
If we divide 283 by 31, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 4 after subtracting 279 from 283.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 31

Let's proceed to step 4:
31 goes into 44 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 91.0
The remainder is 13 after subtracting 31 from 44.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 31

Step 5:
31 can be fit into 132 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 914.0
If we take 124 away from 132, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 31

Step 6:
86 divided by 31 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 9142.0
If we subtract 62 from 86, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
240 divided by 31 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 9142.7
Subtracting 217 from 240 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 8:
31 goes into 230 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 9142.77
Deduct 217 from 230 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 9142.77 with a remaining 0.013.
