415809 divided by 31 
The aim is to understand the frequency of 31 in 415809.

Moving on to step 1:
The number 31 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 31

Step 2:
31 can be fit into 41 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 31 from 41 and we're left with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 31

Let's proceed to step 3:
31 goes into 105 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 93 from 105 leaves us with 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 31

Step 4:
31 goes into 128 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
The remainder is 4 after subtracting 124 from 128.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 31

On to step 5:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1341.0
Subtract 31 from 40 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 31

On to step 6:
99 divided by 31 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 13413.0
Deduct 93 from 99 and we're left with 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 7:
60 divided by 31 is 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 13413.1
Subtracting 31 from 60 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 8:
31 goes into 290 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 13413.19
The remainder is 11 after subtracting 279 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
31 can be fit into 110 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 13413.193
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
170 divided by 31 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 13413.1935
Deduct 155 from 170 and we're left 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.

Going ahead to step 11:
31 goes into 150 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 13413.19354
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.

Advancing to step 12:
If we divide 260 by 31, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 13413.193548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
120 divided by 31 is 3 with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 13413.1935483
The remainder is 27 after subtracting 93 from 120.
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 14:
The number 31 fits into 270 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 13413.19354838
Subtract 248 from 270 to 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.

The final result is 13413.19354838 with a remainder of 2.2e-08.
