251686 ÷ 843 
Let's see how many times 843 fits into 251686.

Going ahead to step 1:
When dividing 2 by 843, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 843

Step 2:
The number 843 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 843

Advancing to step 3:
The number 843 fits into 251 0 times, leaving a remainder of 251.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 251 after subtracting 0 from 251.
Bring next digit (6) of the dividend behind the 251 and repeat the process: 2516 / 843

On to step 4:
843 goes into 2516 2 times with a remainder of 830.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 830 after subtracting 1686 from 2516.
Fetch the next digit (8) from the dividend, attach it to 830 and continue: 8308 / 843

Step 5:
If we divide 8308 by 843, we get 9 and a remainder of 721.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 7587 away from 8308, we end up with 721.
Include the next digit (6) from the dividend after 721, then repeat: 7216 / 843

Advancing to step 6:
If we divide 7216 by 843, we get 8 and a remainder of 472.
The number 8 becomes the next digit in our result. 
Result so far: 298.0
Subtract 6744 from 7216 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 7:
843 goes into 4720 5 times with a remainder of 505.
The next digit of our result is 5. 
Result so far: 298.5
Deduct 4215 from 4720 and we're left with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

On to step 8:
843 can be fit into 5050 5 times, resulting in a remainder of 835.
The number 5 becomes the next digit in our result. 
Result so far: 298.55
If we subtract 4215 from 5050, we get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

The final outcome is 298.55, with a leftover of 0.835.
