680734 ÷ 81 
We want to figure out the number of times 680734 can be divided by 81.

Let's proceed to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 81

Going ahead to step 2:
81 goes into 68 0 times with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (0) from the dividend, add it to 68, then carry on: 680 / 81

Going ahead to step 3:
680 divided by 81 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 648 away from 680, we end up with 32.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 81

Let's proceed to step 4:
81 goes into 327 4 times with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 84.0
The remainder is 3 after subtracting 324 from 327.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 81

Going ahead to step 5:
The number 81 fits into 33 0 times, leaving a remainder of 33.
The next digit of our result is 0. 
Result so far: 840.0
If we subtract 0 from 33, we get 33.
Include the next digit (4) from the dividend after 33, then repeat: 334 / 81

Going ahead to step 6:
The number 81 fits into 334 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 8404.0
If we subtract 324 from 334, we get 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 7:
81 can be fit into 100 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8404.1
Deduct 81 from 100 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 8404.12
The remainder is 28 after subtracting 162 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
81 goes into 280 3 times with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 8404.123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
The number 81 fits into 370 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 8404.1234
The remainder is 46 after subtracting 324 from 370.
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 11:
81 can be fit into 460 5 times, resulting in a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 8404.12345
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.

Moving on to step 12:
The number 81 fits into 550 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 8404.123456
Subtracting 486 from 550 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 13:
When dividing 640 by 81, we get 7 with a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 8404.1234567
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 14:
If we divide 730 by 81, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 8404.12345679
The remainder is 1 after subtracting 729 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 8404.12345679 with a remaining 1e-09.
