We're dividing 256420 by 31 
Our goal is to divide 256420 by 31.

Moving on to step 1:
The number 31 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 31

Going ahead to step 2:
When dividing 25 by 31, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 31

Going ahead to step 3:
31 can be fit into 256 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 248 from 256 leaves us with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 31

Let's proceed to step 4:
31 goes into 84 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we take 62 away from 84, we end up with 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 31

Let's proceed to step 5:
222 divided by 31 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 827.0
If we subtract 217 from 222, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 31

Moving on to step 6:
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: 8271.0
Subtracting 31 from 50 leaves us with 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 7:
190 divided by 31 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 8271.6
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.

Step 8:
When dividing 40 by 31, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 8271.61
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
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: 8271.612
Deduct 62 from 90 and we're left 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.

Step 10:
31 goes into 280 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 8271.6129
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.

Advancing to step 11:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8271.6129
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.

Moving on to step 12:
If we divide 100 by 31, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 8271.612903
If we take 93 away from 100, we end up 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.

Advancing to step 13:
70 divided by 31 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 8271.6129032
Deduct 62 from 70 and we're left with 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:
When dividing 80 by 31, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 8271.61290322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 8271.61290322 with a remaining 1.8e-08.
