We divide 408455 by 81
We're looking to find how many times 81 goes into 408455.

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.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 81

Advancing to step 2:
81 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 81

On to step 3:
When dividing 408 by 81, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 5.0
If we take 405 away from 408, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 81

On to step 4:
34 divided by 81 is 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 50.0
If we take 0 away from 34, we end up with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 81

On to step 5:
The number 81 fits into 345 4 times, leaving a remainder of 21.
The next digit of our result is 4. 
Result so far: 504.0
The remainder is 21 after subtracting 324 from 345.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 81

Going ahead to step 6:
When dividing 215 by 81, we get 2 with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 5042.0
Deduct 162 from 215 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 5042.6
If we take 486 away from 530, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
When dividing 440 by 81, we get 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5042.65
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
The number 81 fits into 350 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 5042.654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
If we divide 260 by 81, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 5042.6543
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 5042.65432
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
81 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 5042.65432
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 5042.6543209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
The number 81 fits into 710 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 5042.65432098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 5042.65432098, and the remainder is 6.2e-08.
