We divide 418080 by 81
We want to divide 418080 by 81.

On to step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 81

On to step 2:
If we divide 41 by 81, we get 0 and a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Bring next digit (8) of the dividend behind the 41 and repeat the process: 418 / 81

Advancing to step 3:
The number 81 fits into 418 5 times, leaving a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 405 away from 418, we end up with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 81

Let's proceed to step 4:
When dividing 130 by 81, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 51.0
If we take 81 away from 130, we end up with 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 81

Going ahead to step 5:
81 can be fit into 498 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 516.0
Deduct 486 from 498 and we're left with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 81

On to step 6:
81 can be fit into 120 1 times, resulting in a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 5161.0
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.

On to step 7:
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: 5161.4
Deduct 324 from 390 and we're left 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 8:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 5161.48
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.

Step 9:
81 goes into 120 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 5161.481
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.

On to step 10:
81 can be fit into 390 4 times, resulting in a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 5161.4814
Deduct 324 from 390 and we're left 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.

Step 11:
The number 81 fits into 660 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 5161.48148
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
120 divided by 81 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 5161.481481
Deduct 81 from 120 and we're left 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.

Moving on to step 13:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 5161.4814814
Deduct 324 from 390 and we're left 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.

On to step 14:
When dividing 660 by 81, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 5161.48148148
Subtract 648 from 660 to 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.

The final result is 5161.48148148 with a remainder of 1.2e-08.
