We divide 853966 by 31
We're looking to find how many times 31 goes into 853966.

Advancing to step 1:
31 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 31

Advancing to step 2:
31 can be fit into 85 2 times, resulting in a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 62 from 85 and we're left with 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 31

Let's proceed to step 3:
When dividing 233 by 31, we get 7 with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 217 from 233 to get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 31

Moving on to step 4:
When dividing 169 by 31, we get 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 275.0
The remainder is 14 after subtracting 155 from 169.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 31

On to step 5:
The number 31 fits into 146 4 times, leaving a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 2754.0
Subtract 124 from 146 to get 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 31

Going ahead to step 6:
When dividing 226 by 31, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 27547.0
Deduct 217 from 226 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 divided by 31 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 27547.2
Subtracting 62 from 90 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 8:
When dividing 280 by 31, we get 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 27547.29
If we take 279 away from 280, we end up 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.

On to step 9:
When dividing 10 by 31, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 27547.29
Subtracting 0 from 10 leaves us 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.

Moving on to step 10:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 27547.2903
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.

Going ahead to step 11:
70 divided by 31 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 27547.29032
The remainder is 8 after subtracting 62 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
If we divide 80 by 31, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 27547.290322
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 27547.290322, with a leftover of 1.8e-06.
