We're dividing 71790726 by 789 
Let's see how many times 789 fits into 71790726.

Going ahead to step 1:
If we divide 7 by 789, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 789

On to step 2:
789 goes into 71 0 times with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Include the next digit (7) from the dividend after 71, then repeat: 717 / 789

On to step 3:
789 goes into 717 0 times with a remainder of 717.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 717 after subtracting 0 from 717.
Include the next digit (9) from the dividend after 717, then repeat: 7179 / 789

Let's proceed to step 4:
The number 789 fits into 7179 9 times, leaving a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 78 after subtracting 7101 from 7179.
Grab the next digit (0) from the dividend, add it to 78, then carry on: 780 / 789

Going ahead to step 5:
When dividing 780 by 789, we get 0 with a remainder of 780.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 780 and we're left with 780.
Append the next digit (7) from the dividend to 780 and continue with: 7807 / 789

Let's proceed to step 6:
If we divide 7807 by 789, we get 9 and a remainder of 706.
The next digit of our result is 9. 
Result so far: 909.0
If we subtract 7101 from 7807, we get 706.
Append the next digit (2) from the dividend to 706 and continue with: 7062 / 789

On to step 7:
The number 789 fits into 7062 8 times, leaving a remainder of 750.
The next digit of our result is 8. 
Result so far: 9098.0
If we take 6312 away from 7062, we end up with 750.
Fetch the next digit (6) from the dividend, attach it to 750 and continue: 7506 / 789

Moving on to step 8:
The number 789 fits into 7506 9 times, leaving a remainder of 405.
Use 9 as the next digit of our solution. 
Result so far: 90989.0
The remainder is 405 after subtracting 7101 from 7506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 9:
If we divide 4050 by 789, we get 5 and a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 90989.5
If we subtract 3945 from 4050, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 10:
789 goes into 1050 1 times with a remainder of 261.
Write down 1 as next digit of the result. 
Result so far: 90989.51
Subtracting 789 from 1050 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 11:
The number 789 fits into 2610 3 times, leaving a remainder of 243.
Record the quotient 3 as the next digit in the result. 
Result so far: 90989.513
Subtracting 2367 from 2610 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 12:
When dividing 2430 by 789, we get 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 90989.5133
Subtract 2367 from 2430 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.

After the division, we end up with 90989.5133 and a remainder of 0.00063.
