Let's divide 680090 by 81
We want to figure out the number of times 680090 can be divided by 81.

Let's proceed to step 1:
If we divide 6 by 81, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 81

Advancing to step 2:
81 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 81

Let's proceed to step 3:
The number 81 fits into 680 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 648 from 680 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 81

On to step 4:
320 divided by 81 is 3 with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 243 from 320 and we're left with 77.
Fetch the next digit (9) from the dividend, attach it to 77 and continue: 779 / 81

Step 5:
81 goes into 779 9 times with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 839.0
Subtracting 729 from 779 leaves us with 50.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 81

Advancing to step 6:
The number 81 fits into 500 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 8396.0
If we subtract 486 from 500, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 81 is 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 8396.1
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
81 can be fit into 590 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 8396.17
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
81 can be fit into 230 2 times, resulting in a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 8396.172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
If we divide 680 by 81, we get 8 and a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8396.1728
Deduct 648 from 680 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
When dividing 320 by 81, we get 3 with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 8396.17283
Subtract 243 from 320 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 12:
If we divide 770 by 81, we get 9 and a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 8396.172839
Deduct 729 from 770 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
81 goes into 410 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8396.1728395
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
The number 81 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 8396.1728395
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 8396.1728395, and the remainder is 5e-08.
