859618 ÷ 31 
We want to figure out the number of times 859618 can be divided by 31.

Moving on to step 1:
When dividing 8 by 31, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 31

Going ahead to step 2:
85 divided by 31 is 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 62 from 85 and we're left with 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 31

Going ahead to step 3:
31 can be fit into 239 7 times, resulting in a remainder of 22.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 217 from 239 and we're left with 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 31

On to step 4:
226 divided by 31 is 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 277.0
The remainder is 9 after subtracting 217 from 226.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 31

Going ahead to step 5:
When dividing 91 by 31, we get 2 with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 2772.0
Subtracting 62 from 91 leaves us with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 31

On to step 6:
The number 31 fits into 298 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 27729.0
Subtract 279 from 298 to 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.

On to step 7:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 27729.6
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
31 can be fit into 40 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 27729.61
Subtract 31 from 40 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 31, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 27729.612
The remainder is 28 after subtracting 62 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
When dividing 280 by 31, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 27729.6129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
The number 31 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 27729.6129
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
If we divide 100 by 31, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 27729.612903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
When dividing 70 by 31, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 27729.6129032
If we subtract 62 from 70, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 27729.61290322
Deduct 62 from 80 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.

The final outcome is 27729.61290322, with a leftover of 1.8e-08.
