398263 divided by 81 
We're looking to find how many times 81 goes into 398263.

Going ahead to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 81

Moving on to step 2:
If we divide 39 by 81, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 81

On to step 3:
When dividing 398 by 81, we get 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 4.0
If we take 324 away from 398, we end up with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 81

Let's proceed to step 4:
If we divide 742 by 81, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we subtract 729 from 742, we get 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 81

Moving on to step 5:
When dividing 136 by 81, we get 1 with a remainder of 55.
Record the quotient 1 as the next digit in the result. 
Result so far: 491.0
Deduct 81 from 136 and we're left with 55.
Take the next digit (3) from the dividend and append it to 55, then repeat: 553 / 81

Moving on to step 6:
When dividing 553 by 81, we get 6 with a remainder of 67.
Use 6 as the next digit of our solution. 
Result so far: 4916.0
If we subtract 486 from 553, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
When dividing 670 by 81, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 4916.8
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
81 goes into 220 2 times with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 4916.82
Subtracting 162 from 220 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
580 divided by 81 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 4916.827
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
130 divided by 81 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 4916.8271
If we take 81 away from 130, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 11:
490 divided by 81 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4916.82716
Subtract 486 from 490 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
40 divided by 81 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4916.82716
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
If we divide 400 by 81, we get 4 and a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4916.8271604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
81 goes into 760 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 4916.82716049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 4916.82716049 with a balance of 3.1e-08.
