Let's divide 408150 by 81
Our goal is to divide 408150 by 81.

Moving on to step 1:
If we divide 4 by 81, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 81

Advancing to step 2:
The number 81 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (8) from the dividend, attach it to 40 and continue: 408 / 81

Moving on to step 3:
The number 81 fits into 408 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 3 after subtracting 405 from 408.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 81

Moving on to step 4:
If we divide 31 by 81, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 50.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 81

Going ahead to step 5:
315 divided by 81 is 3 with a remainder of 72.
The next digit of our result is 3. 
Result so far: 503.0
Subtract 243 from 315 to get 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 81

Going ahead to step 6:
81 goes into 720 8 times with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 5038.0
Subtract 648 from 720 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
When dividing 720 by 81, we get 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 5038.8
Deduct 648 from 720 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 8:
When dividing 720 by 81, we get 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 5038.88
Subtract 648 from 720 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 5038.88, and the remainder is 0.072.
