Let's divide 860206 by 31
The aim is to understand the frequency of 31 in 860206.

Step 1:
If we divide 8 by 31, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 31

Let's proceed to step 2:
31 goes into 86 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 62 from 86 leaves us with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 31

Moving on to step 3:
31 goes into 240 7 times with a remainder of 23.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 217 from 240 leaves us with 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 31

Step 4:
31 goes into 232 7 times with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 277.0
If we take 217 away from 232, we end up with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 31

On to step 5:
31 goes into 150 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 2774.0
Subtracting 124 from 150 leaves us with 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 31

Moving on to step 6:
266 divided by 31 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 27748.0
Deduct 248 from 266 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
The number 31 fits into 180 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 27748.5
Subtracting 155 from 180 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
250 divided by 31 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 27748.58
Subtract 248 from 250 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
If we divide 20 by 31, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 27748.58
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
31 goes into 200 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 27748.5806
Subtracting 186 from 200 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
31 goes into 140 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 27748.58064
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.

Going ahead to step 12:
The number 31 fits into 160 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 27748.580645
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 27748.5806451
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.

Step 14:
The number 31 fits into 190 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 27748.58064516
If we take 186 away from 190, we end up 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.

Our division results in 27748.58064516 with a remaining 4e-09.
