482470 ÷ 31 
The aim is to understand the frequency of 31 in 482470.

Step 1:
When dividing 4 by 31, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 31

Step 2:
When dividing 48 by 31, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 17 after subtracting 31 from 48.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 31

Advancing to step 3:
172 divided by 31 is 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 17 after subtracting 155 from 172.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 31

Step 4:
When dividing 174 by 31, we get 5 with a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 155.0
The remainder is 19 after subtracting 155 from 174.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 31

Moving on to step 5:
When dividing 197 by 31, we get 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 1556.0
If we take 186 away from 197, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 31

Let's proceed to step 6:
The number 31 fits into 110 3 times, leaving a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 15563.0
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 31, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15563.5
If we subtract 155 from 170, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
The number 31 fits into 150 4 times, leaving a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 15563.54
The remainder is 26 after subtracting 124 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
31 goes into 260 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 15563.548
If we subtract 248 from 260, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
When dividing 120 by 31, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 15563.5483
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.

Let's proceed to step 11:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 15563.54838
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.

Going ahead to step 12:
If we divide 220 by 31, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 15563.548387
Subtracting 217 from 220 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 15563.548387
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.

Let's proceed to step 14:
300 divided by 31 is 9 with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 15563.54838709
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 15563.54838709, and the remainder is 2.1e-08.
