We look at the division of 846643 by 31 
We're looking to find how many times 31 goes into 846643.

Going ahead to step 1:
If we divide 8 by 31, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 31

Let's proceed to step 2:
84 divided by 31 is 2 with a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 62 away from 84, we end up with 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 31

Let's proceed to step 3:
When dividing 226 by 31, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 217 from 226, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 31

Moving on to step 4:
96 divided by 31 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 273.0
If we subtract 93 from 96, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 31

Going ahead to step 5:
The number 31 fits into 34 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 2731.0
The remainder is 3 after subtracting 31 from 34.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 31

On to step 6:
33 divided by 31 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 27311.0
If we take 31 away from 33, we end up with 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 7:
31 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 27311.0
Subtract 0 from 20 to get 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 8:
If we divide 200 by 31, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 27311.06
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
The number 31 fits into 140 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 27311.064
Subtract 124 from 140 to 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.

On to step 10:
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: 27311.0645
Deduct 155 from 160 and we're left with 5.
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 11:
31 can be fit into 50 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 27311.06451
The remainder is 19 after subtracting 31 from 50.
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 12:
When dividing 190 by 31, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 27311.064516
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.

Step 13:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 27311.0645161
Subtracting 31 from 40 leaves us 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.

Let's proceed to step 14:
When dividing 90 by 31, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 27311.06451612
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 27311.06451612 with a balance of 2.8e-08.
