Let's divide 486066 by 81
We want to divide 486066 by 81.

Advancing to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 81

Advancing to step 2:
If we divide 48 by 81, we get 0 and a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 81

Step 3:
The number 81 fits into 486 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 486 from 486, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 81

Advancing to step 4:
The number 81 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 60.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 81

Going ahead to step 5:
If we divide 6 by 81, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 600.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 81

Let's proceed to step 6:
66 divided by 81 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 6000.0
Subtract 0 from 66 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
81 goes into 660 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 6000.8
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
The number 81 fits into 120 1 times, leaving a remainder of 39.
The next digit of our result is 1. 
Result so far: 6000.81
If we subtract 81 from 120, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 6000.814
Subtract 324 from 390 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
81 goes into 660 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6000.8148
Deduct 648 from 660 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
The number 81 fits into 120 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 6000.81481
Subtracting 81 from 120 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
If we divide 390 by 81, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 6000.814814
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 13:
81 goes into 660 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 6000.8148148
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
If we divide 120 by 81, we get 1 and a remainder of 39.
The next digit of our result is 1. 
Result so far: 6000.81481481
The remainder is 39 after subtracting 81 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 6000.81481481 and a remainder of 3.9e-08.
