441831 ÷ 31 
The aim is to understand the frequency of 31 in 441831.

On to step 1:
If we divide 4 by 31, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 31

On to step 2:
When dividing 44 by 31, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we take 31 away from 44, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 31

Going ahead to step 3:
If we divide 131 by 31, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 124 away from 131, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 31

Going ahead to step 4:
When dividing 78 by 31, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 142.0
The remainder is 16 after subtracting 62 from 78.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 31

On to step 5:
163 divided by 31 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 1425.0
If we take 155 away from 163, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 31

On to step 6:
If we divide 81 by 31, we get 2 and a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 14252.0
If we take 62 away from 81, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
190 divided by 31 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 14252.6
Subtract 186 from 190 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
If we divide 40 by 31, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 14252.61
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
31 goes into 90 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 14252.612
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
280 divided by 31 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 14252.6129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
10 divided by 31 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 14252.6129
Deduct 0 from 10 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.

Step 12:
If we divide 100 by 31, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 14252.612903
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.

Moving on to step 13:
When dividing 70 by 31, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 14252.6129032
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.

Let's proceed to step 14:
80 divided by 31 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 14252.61290322
If we subtract 62 from 80, we get 18.
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 outcome is 14252.61290322, with a leftover of 1.8e-08.
