857239 ÷ 71 
We want to divide 857239 by 71.

Advancing to step 1:
8 divided by 71 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 71

Moving on to step 2:
The number 71 fits into 85 1 times, leaving a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 71 away from 85, we end up with 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 71

Let's proceed to step 3:
The number 71 fits into 147 2 times, leaving a remainder of 5.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 142 from 147 to get 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 71

On to step 4:
The number 71 fits into 52 0 times, leaving a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtracting 0 from 52 leaves us with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 71

Step 5:
When dividing 523 by 71, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 1207.0
If we subtract 497 from 523, we get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 71

Going ahead to step 6:
71 can be fit into 269 3 times, resulting in a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 12073.0
If we subtract 213 from 269, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 7:
71 can be fit into 560 7 times, resulting in a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 12073.7
Subtract 497 from 560 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
71 can be fit into 630 8 times, resulting in a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 12073.78
If we take 568 away from 630, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 9:
If we divide 620 by 71, we get 8 and a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 12073.788
If we take 568 away from 620, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The quotient of the division is 12073.788, and the remainder is 0.0052.
