Let's divide 664074 by 81
Our goal is to divide 664074 by 81.

Let's proceed to step 1:
6 divided by 81 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 81

Moving on to step 2:
81 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 81

Going ahead to step 3:
The number 81 fits into 664 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 16 after subtracting 648 from 664.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 81

Advancing to step 4:
When dividing 160 by 81, we get 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 81 away from 160, we end up with 79.
Fetch the next digit (7) from the dividend, attach it to 79 and continue: 797 / 81

Advancing to step 5:
The number 81 fits into 797 9 times, leaving a remainder of 68.
Put 9 as the next digit of the answer. 
Result so far: 819.0
The remainder is 68 after subtracting 729 from 797.
Fetch the next digit (4) from the dividend, attach it to 68 and continue: 684 / 81

Let's proceed to step 6:
The number 81 fits into 684 8 times, leaving a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 8198.0
Deduct 648 from 684 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
When dividing 360 by 81, we get 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 8198.4
If we subtract 324 from 360, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
81 goes into 360 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 8198.44
Subtracting 324 from 360 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 8198.44 with a remainder of 0.036.
