We divide 709912 by 81
We're looking to find how many times 81 goes into 709912.

On to step 1:
81 goes into 7 0 times 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.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 81

Let's proceed to step 2:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 81

Going ahead to step 3:
81 can be fit into 709 8 times, resulting in a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 61 after subtracting 648 from 709.
Bring next digit (9) of the dividend behind the 61 and repeat the process: 619 / 81

Advancing to step 4:
The number 81 fits into 619 7 times, leaving a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we take 567 away from 619, we end up with 52.
Include the next digit (1) from the dividend after 52, then repeat: 521 / 81

Let's proceed to step 5:
If we divide 521 by 81, we get 6 and a remainder of 35.
Use 6 as the next digit of our solution. 
Result so far: 876.0
Subtracting 486 from 521 leaves us with 35.
Bring next digit (2) of the dividend behind the 35 and repeat the process: 352 / 81

Advancing to step 6:
352 divided by 81 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 8764.0
The remainder is 28 after subtracting 324 from 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
When dividing 280 by 81, we get 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 8764.3
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
81 goes into 370 4 times with a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 8764.34
If we take 324 away from 370, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
The number 81 fits into 460 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 8764.345
Subtracting 405 from 460 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
550 divided by 81 is 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 8764.3456
The remainder is 64 after subtracting 486 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
The number 81 fits into 640 7 times, leaving a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 8764.34567
Subtracting 567 from 640 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 12:
If we divide 730 by 81, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8764.345679
Subtract 729 from 730 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
When dividing 10 by 81, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8764.345679
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
The number 81 fits into 100 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 8764.34567901
The remainder is 19 after subtracting 81 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 8764.34567901, with a leftover of 1.9e-08.
