712749 divided by 81 
We want to divide 712749 by 81.

On to step 1:
If we divide 7 by 81, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 81

Step 2:
When dividing 71 by 81, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 81

Let's proceed to step 3:
81 can be fit into 712 8 times, resulting in a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 648 away from 712, we end up with 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 81

Advancing to step 4:
81 goes into 647 7 times with a remainder of 80.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 567 from 647 leaves us with 80.
Grab the next digit (4) from the dividend, add it to 80, then carry on: 804 / 81

Advancing to step 5:
804 divided by 81 is 9 with a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 879.0
Deduct 729 from 804 and we're left with 75.
Include the next digit (9) from the dividend after 75, then repeat: 759 / 81

Step 6:
759 divided by 81 is 9 with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 8799.0
Subtract 729 from 759 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
81 can be fit into 300 3 times, resulting in a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 8799.3
Subtract 243 from 300 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 8:
81 goes into 570 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 8799.37
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
If we divide 30 by 81, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 8799.37
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
If we divide 300 by 81, we get 3 and a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 8799.3703
Subtracting 243 from 300 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 11:
81 goes into 570 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 8799.37037
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
If we divide 30 by 81, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8799.37037
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
300 divided by 81 is 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 8799.3703703
Subtract 243 from 300 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 14:
The number 81 fits into 570 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 8799.37037037
If we subtract 567 from 570, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 8799.37037037, with a leftover of 3e-09.
