71310707 ÷ 89 
Our goal is to divide 71310707 by 89.

Going ahead to step 1:
89 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 89

Moving on to step 2:
71 divided by 89 is 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Fetch the next digit (3) from the dividend, attach it to 71 and continue: 713 / 89

Going ahead to step 3:
89 goes into 713 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 712 from 713 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 89

On to step 4:
89 can be fit into 11 0 times, resulting in a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 11 leaves us with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 89

Let's proceed to step 5:
110 divided by 89 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 801.0
Subtracting 89 from 110 leaves us with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 89

Going ahead to step 6:
The number 89 fits into 217 2 times, leaving a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 8012.0
Subtract 178 from 217 to get 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 89

Step 7:
390 divided by 89 is 4 with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 80124.0
Subtracting 356 from 390 leaves us with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 89

Step 8:
The number 89 fits into 347 3 times, leaving a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 801243.0
Deduct 267 from 347 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
89 goes into 800 8 times with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 801243.8
If we take 712 away from 800, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
The number 89 fits into 880 9 times, leaving a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 801243.89
The remainder is 79 after subtracting 801 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
If we divide 790 by 89, we get 8 and a remainder of 78.
The next digit of our result is 8. 
Result so far: 801243.898
Deduct 712 from 790 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
The number 89 fits into 780 8 times, leaving a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 801243.8988
If we take 712 away from 780, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 801243.8988 with a remainder of 0.00068.
