We look at the division of 71486930 by 857 
Let's see how many times 857 fits into 71486930.

Going ahead to step 1:
857 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 857

Advancing to step 2:
The number 857 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 857

On to step 3:
857 can be fit into 714 0 times, resulting in a remainder of 714.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 714 after subtracting 0 from 714.
Grab the next digit (8) from the dividend, add it to 714, then carry on: 7148 / 857

Moving on to step 4:
The number 857 fits into 7148 8 times, leaving a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 6856 from 7148 leaves us with 292.
Grab the next digit (6) from the dividend, add it to 292, then carry on: 2926 / 857

Let's proceed to step 5:
857 goes into 2926 3 times with a remainder of 355.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we subtract 2571 from 2926, we get 355.
Bring next digit (9) of the dividend behind the 355 and repeat the process: 3559 / 857

Let's proceed to step 6:
When dividing 3559 by 857, we get 4 with a remainder of 131.
The next digit of our result is 4. 
Result so far: 834.0
Deduct 3428 from 3559 and we're left with 131.
Bring next digit (3) of the dividend behind the 131 and repeat the process: 1313 / 857

On to step 7:
When dividing 1313 by 857, we get 1 with a remainder of 456.
Write down 1 as next digit of the result. 
Result so far: 8341.0
If we take 857 away from 1313, we end up with 456.
Include the next digit (0) from the dividend after 456, then repeat: 4560 / 857

Moving on to step 8:
857 goes into 4560 5 times with a remainder of 275.
Write down 5 as next digit of the result. 
Result so far: 83415.0
Subtract 4285 from 4560 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 9:
857 goes into 2750 3 times with a remainder of 179.
Record the quotient 3 as the next digit in the result. 
Result so far: 83415.3
Subtract 2571 from 2750 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 10:
857 can be fit into 1790 2 times, resulting in a remainder of 76.
The next digit of our result is 2. 
Result so far: 83415.32
Subtracting 1714 from 1790 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
857 can be fit into 760 0 times, resulting in a remainder of 760.
The next digit of our result is 0. 
Result so far: 83415.32
The remainder is 760 after subtracting 0 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 12:
7600 divided by 857 is 8 with a remainder of 744.
Write down 8 as next digit of the result. 
Result so far: 83415.3208
Deduct 6856 from 7600 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

Let's proceed to step 13:
857 goes into 7440 8 times with a remainder of 584.
Use 8 as the next digit of our solution. 
Result so far: 83415.32088
Subtracting 6856 from 7440 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Our division results in 83415.32088 with a remaining 0.000584.
