71035708 ÷ 815 
We want to divide 71035708 by 815.

Going ahead to step 1:
When dividing 7 by 815, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 815

Step 2:
If we divide 71 by 815, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Take the next digit (0) from the dividend and append it to 71, then repeat: 710 / 815

Let's proceed to step 3:
If we divide 710 by 815, we get 0 and a remainder of 710.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 710 leaves us with 710.
Take the next digit (3) from the dividend and append it to 710, then repeat: 7103 / 815

Let's proceed to step 4:
7103 divided by 815 is 8 with a remainder of 583.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 583 after subtracting 6520 from 7103.
Append the next digit (5) from the dividend to 583 and continue with: 5835 / 815

Going ahead to step 5:
The number 815 fits into 5835 7 times, leaving a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 5705 from 5835 and we're left with 130.
Take the next digit (7) from the dividend and append it to 130, then repeat: 1307 / 815

Moving on to step 6:
1307 divided by 815 is 1 with a remainder of 492.
Use 1 as the next digit of our solution. 
Result so far: 871.0
Subtract 815 from 1307 to get 492.
Append the next digit (0) from the dividend to 492 and continue with: 4920 / 815

Going ahead to step 7:
If we divide 4920 by 815, we get 6 and a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 8716.0
If we take 4890 away from 4920, we end up with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 815

Step 8:
The number 815 fits into 308 0 times, leaving a remainder of 308.
Use 0 as the next digit of our solution. 
Result so far: 87160.0
If we subtract 0 from 308, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 9:
The number 815 fits into 3080 3 times, leaving a remainder of 635.
Put 3 as the next digit of the answer. 
Result so far: 87160.3
The remainder is 635 after subtracting 2445 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

On to step 10:
If we divide 6350 by 815, we get 7 and a remainder of 645.
Put 7 as the next digit of the answer. 
Result so far: 87160.37
If we take 5705 away from 6350, we end up with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 11:
If we divide 6450 by 815, we get 7 and a remainder of 745.
Put 7 as the next digit of the answer. 
Result so far: 87160.377
If we take 5705 away from 6450, we end up with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

The final outcome is 87160.377, with a leftover of 0.0745.
