851825 ÷ 31 
Let's see how many times 31 fits into 851825.

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
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 31

Advancing to step 2:
If we divide 85 by 31, we get 2 and a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 62 from 85 and we're left with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 31

Step 3:
The number 31 fits into 231 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 217 from 231 and we're left with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 31

Advancing to step 4:
The number 31 fits into 148 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 274.0
If we subtract 124 from 148, we get 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 31

Going ahead to step 5:
If we divide 242 by 31, we get 7 and a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 2747.0
The remainder is 25 after subtracting 217 from 242.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 31

Advancing 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
Subtracting 248 from 255 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.

Advancing to step 7:
31 can be fit into 70 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 27478.2
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.

Step 8:
If we divide 80 by 31, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 27478.22
If we subtract 62 from 80, we 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.

In conclusion, the division gives 27478.22 with a balance of 0.018.
