856729 ÷ 31 
The aim is to understand the frequency of 31 in 856729.

Going ahead to step 1:
31 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 31

Advancing to step 2:
The number 31 fits into 85 2 times, leaving a remainder of 23.
The next digit of our result is 2. 
Result so far: 2.0
If we take 62 away from 85, we end up with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 31

Step 3:
31 goes into 236 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 217 from 236 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 31

Moving on to step 4:
If we divide 197 by 31, we get 6 and a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 276.0
If we subtract 186 from 197, we get 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 31

Moving on to step 5:
If we divide 112 by 31, we get 3 and a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 2763.0
If we subtract 93 from 112, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 31

Advancing to step 6:
199 divided by 31 is 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 27636.0
The remainder is 13 after subtracting 186 from 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
31 can be fit into 130 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 27636.4
Subtracting 124 from 130 leaves us 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.

On to step 8:
The number 31 fits into 60 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 27636.41
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.

Let's proceed to step 9:
31 can be fit into 290 9 times, resulting in a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 27636.419
Deduct 279 from 290 and we're left 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.

On to step 10:
31 goes into 110 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 27636.4193
Deduct 93 from 110 and we're left 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.

Advancing to step 11:
The number 31 fits into 170 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 27636.41935
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 12:
31 can be fit into 150 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 27636.419354
Subtracting 124 from 150 leaves us 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.

On to step 13:
31 goes into 260 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 27636.4193548
Deduct 248 from 260 and we're left 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.

Going ahead to step 14:
If we divide 120 by 31, we get 3 and a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 27636.41935483
Deduct 93 from 120 and we're left 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.

The quotient of the division is 27636.41935483, and the remainder is 2.7e-08.
