We divide 672064 by 81
Our goal is to divide 672064 by 81.

Let's proceed to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 81

Step 2:
81 goes into 67 0 times with a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 81

Step 3:
81 can be fit into 672 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 648 from 672, we get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 81

On to step 4:
81 goes into 240 2 times with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 82.0
The remainder is 78 after subtracting 162 from 240.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 81

Let's proceed to step 5:
786 divided by 81 is 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 829.0
Subtracting 729 from 786 leaves us with 57.
Fetch the next digit (4) from the dividend, attach it to 57 and continue: 574 / 81

Going ahead to step 6:
The number 81 fits into 574 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 8297.0
Deduct 567 from 574 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 81, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 8297.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
700 divided by 81 is 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8297.08
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
81 goes into 520 6 times with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 8297.086
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 8297.0864
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 81 is 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 8297.08641
Deduct 81 from 160 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 12:
81 goes into 790 9 times with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 8297.086419
Subtract 729 from 790 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 13:
The number 81 fits into 610 7 times, leaving a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 8297.0864197
If we subtract 567 from 610, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 14:
81 goes into 430 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 8297.08641975
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 8297.08641975 and a remainder of 2.5e-08.
