Let's divide 440574 by 31
The aim is to understand the frequency of 31 in 440574.

Advancing to step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 31

Going ahead to step 2:
44 divided by 31 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 31 from 44 to get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 31

Advancing to step 3:
31 can be fit into 130 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 124 from 130, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 31

Let's proceed to step 4:
31 goes into 65 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 142.0
If we take 62 away from 65, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 31

On to step 5:
31 goes into 37 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1421.0
Deduct 31 from 37 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 31

On to step 6:
31 can be fit into 64 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 14212.0
Subtracting 62 from 64 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 31, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 14212.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
31 goes into 200 6 times with a remainder of 14.
The next digit of our result is 6. 
Result so far: 14212.06
Subtract 186 from 200 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
140 divided by 31 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14212.064
If we subtract 124 from 140, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 31 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 14212.0645
Deduct 155 from 160 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
If we divide 50 by 31, we get 1 and a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 14212.06451
If we subtract 31 from 50, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 12:
31 goes into 190 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 14212.064516
Deduct 186 from 190 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 31, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 14212.0645161
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
90 divided by 31 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 14212.06451612
The remainder is 28 after subtracting 62 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 14212.06451612 with a remainder of 2.8e-08.
