We divide 493605 by 31
The aim is to understand the frequency of 31 in 493605.

Advancing to step 1:
31 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 31

Advancing to step 2:
31 goes into 49 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 31 from 49 leaves us with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 31

Advancing to step 3:
31 goes into 183 5 times with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 155 from 183 leaves us with 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 31

Advancing to step 4:
31 can be fit into 286 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 159.0
Deduct 279 from 286 and we're left with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 31

On to step 5:
When dividing 70 by 31, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1592.0
Subtract 62 from 70 to get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 31

Going ahead to step 6:
31 goes into 85 2 times with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 15922.0
The remainder is 23 after subtracting 62 from 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
31 goes into 230 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 15922.7
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
31 goes into 130 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 15922.74
Subtract 124 from 130 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 31, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 15922.741
Subtract 31 from 60 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 10:
31 can be fit into 290 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 15922.7419
If we take 279 away from 290, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
31 goes into 110 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 15922.74193
If we subtract 93 from 110, we get 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 12:
170 divided by 31 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15922.741935
If we take 155 away from 170, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
31 can be fit into 150 4 times, resulting in a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 15922.7419354
If we take 124 away from 150, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
31 goes into 260 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 15922.74193548
Subtracting 248 from 260 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.

The quotient of the division is 15922.74193548, and the remainder is 1.2e-08.
