We divide 144286 by 31
The aim is to understand the frequency of 31 in 144286.

On to step 1:
The number 31 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 31

Let's proceed to step 2:
The number 31 fits into 14 0 times, leaving a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 31

Advancing to step 3:
If we divide 144 by 31, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 124 from 144 leaves us with 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 31

Moving on to step 4:
The number 31 fits into 202 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 46.0
The remainder is 16 after subtracting 186 from 202.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 31

On to step 5:
31 can be fit into 168 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 465.0
Subtract 155 from 168 to get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 31

Advancing to step 6:
136 divided by 31 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4654.0
Subtracting 124 from 136 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
When dividing 120 by 31, we get 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 4654.3
Subtracting 93 from 120 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
The number 31 fits into 270 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 4654.38
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
31 goes into 220 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 4654.387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
31 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 4654.387
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 31 fits into 300 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 4654.38709
Subtract 279 from 300 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
31 can be fit into 210 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 4654.387096
If we subtract 186 from 210, 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.

Advancing to step 13:
The number 31 fits into 240 7 times, leaving a remainder of 23.
The next digit of our result is 7. 
Result so far: 4654.3870967
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
31 goes into 230 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 4654.38709677
If we take 217 away from 230, we end up 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 4654.38709677 with a remaining 1.3e-08.
