Let's divide 71658639 by 812
We want to divide 71658639 by 812.

Step 1:
812 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 812

On to step 2:
When dividing 71 by 812, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (6) from the dividend to 71 and continue with: 716 / 812

Going ahead to step 3:
812 can be fit into 716 0 times, resulting in a remainder of 716.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 716, we get 716.
Append the next digit (5) from the dividend to 716 and continue with: 7165 / 812

Let's proceed to step 4:
7165 divided by 812 is 8 with a remainder of 669.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 669 after subtracting 6496 from 7165.
Bring next digit (8) of the dividend behind the 669 and repeat the process: 6698 / 812

Going ahead to step 5:
812 can be fit into 6698 8 times, resulting in a remainder of 202.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtracting 6496 from 6698 leaves us with 202.
Grab the next digit (6) from the dividend, add it to 202, then carry on: 2026 / 812

Let's proceed to step 6:
The number 812 fits into 2026 2 times, leaving a remainder of 402.
The number 2 becomes the next digit in our result. 
Result so far: 882.0
Subtracting 1624 from 2026 leaves us with 402.
Grab the next digit (3) from the dividend, add it to 402, then carry on: 4023 / 812

Step 7:
812 goes into 4023 4 times with a remainder of 775.
The next digit of our result is 4. 
Result so far: 8824.0
Subtracting 3248 from 4023 leaves us with 775.
Take the next digit (9) from the dividend and append it to 775, then repeat: 7759 / 812

Going ahead to step 8:
If we divide 7759 by 812, we get 9 and a remainder of 451.
Write down 9 as next digit of the result. 
Result so far: 88249.0
If we subtract 7308 from 7759, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 9:
812 can be fit into 4510 5 times, resulting in a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 88249.5
Deduct 4060 from 4510 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 10:
If we divide 4500 by 812, we get 5 and a remainder of 440.
Use 5 as the next digit of our solution. 
Result so far: 88249.55
If we take 4060 away from 4500, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final result is 88249.55 with a remainder of 0.44.
