851825 ÷ 31 
We want to divide 851825 by 31.

Let's proceed to step 1:
8 divided by 31 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 31

Moving on to step 2:
31 goes into 85 2 times with a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 62 from 85 to get 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 31

Let's proceed to step 3:
31 goes into 231 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 14 after subtracting 217 from 231.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 31

Moving on to step 4:
148 divided by 31 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 274.0
Deduct 124 from 148 and we're left with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 31

On to step 5:
31 goes into 242 7 times with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 2747.0
Deduct 217 from 242 and we're left with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 31

Let's proceed to step 6:
The number 31 fits into 255 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 27478.0
Subtract 248 from 255 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
31 goes into 70 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 27478.2
Subtracting 62 from 70 leaves us 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.

Going ahead to step 8:
80 divided by 31 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 27478.22
Subtract 62 from 80 to get 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 result is 27478.22 with a remainder of 0.018.
