420768 divided by 81 
We want to divide 420768 by 81.

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
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 81

Moving on to step 2:
81 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 81

Going ahead to step 3:
When dividing 420 by 81, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 15 after subtracting 405 from 420.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 81

Step 4:
When dividing 157 by 81, we get 1 with a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 51.0
The remainder is 76 after subtracting 81 from 157.
Include the next digit (6) from the dividend after 76, then repeat: 766 / 81

Going ahead to step 5:
766 divided by 81 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 519.0
Subtracting 729 from 766 leaves us with 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 81

Step 6:
378 divided by 81 is 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 5194.0
Subtract 324 from 378 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
When dividing 540 by 81, we get 6 with a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 5194.6
Subtracting 486 from 540 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
The number 81 fits into 540 6 times, leaving a remainder of 54.
The number 6 becomes the next digit in our result. 
Result so far: 5194.66
Subtract 486 from 540 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 5194.66 with a remainder of 0.054.
