We divide 64688 by 81
Our goal is to divide 64688 by 81.

Step 1:
6 divided by 81 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 81

Step 2:
When dividing 64 by 81, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 81

Advancing to step 3:
The number 81 fits into 646 7 times, leaving a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 567 from 646 and we're left with 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 81

Let's proceed to step 4:
When dividing 798 by 81, we get 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 79.0
If we take 729 away from 798, we end up with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 81

Advancing to step 5:
81 can be fit into 698 8 times, resulting in a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 798.0
Subtracting 648 from 698 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 6:
500 divided by 81 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 798.6
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 81, we get 1 and a remainder of 59.
The next digit of our result is 1. 
Result so far: 798.61
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:
When dividing 590 by 81, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 798.617
Subtract 567 from 590 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 9:
If we divide 230 by 81, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 798.6172
Subtract 162 from 230 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
680 divided by 81 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 798.61728
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.

Step 11:
The number 81 fits into 320 3 times, leaving a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 798.617283
The remainder is 77 after subtracting 243 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 12:
If we divide 770 by 81, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 798.6172839
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.

Let's proceed to step 13:
81 can be fit into 410 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 798.61728395
Deduct 405 from 410 and we're left 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.

The final outcome is 798.61728395, with a leftover of 5e-09.
