We're dividing 451359 by 81 
Let's see how many times 81 fits into 451359.

Advancing to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 81

Moving on to step 2:
If we divide 45 by 81, we get 0 and a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 81

Going ahead to step 3:
The number 81 fits into 451 5 times, leaving a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 405 from 451 to get 46.
Take the next digit (3) from the dividend and append it to 46, then repeat: 463 / 81

Moving on to step 4:
463 divided by 81 is 5 with a remainder of 58.
The next digit of our result is 5. 
Result so far: 55.0
If we take 405 away from 463, we end up with 58.
Append the next digit (5) from the dividend to 58 and continue with: 585 / 81

Moving on to step 5:
When dividing 585 by 81, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 557.0
If we subtract 567 from 585, we get 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 81

On to step 6:
81 can be fit into 189 2 times, resulting in a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 5572.0
If we take 162 away from 189, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
The number 81 fits into 270 3 times, leaving a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 5572.3
Subtract 243 from 270 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
270 divided by 81 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 5572.33
Subtract 243 from 270 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The quotient of the division is 5572.33, and the remainder is 0.027.
