Let's divide 398038 by 81
We want to figure out the number of times 398038 can be divided by 81.

Step 1:
3 divided by 81 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 81

Going ahead to step 2:
If we divide 39 by 81, we get 0 and a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 81

Advancing to step 3:
If we divide 398 by 81, we get 4 and a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 74 after subtracting 324 from 398.
Include the next digit (0) from the dividend after 74, then repeat: 740 / 81

Going ahead to step 4:
81 can be fit into 740 9 times, resulting in a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 11 after subtracting 729 from 740.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 81

Going ahead to step 5:
81 can be fit into 113 1 times, resulting in a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 491.0
If we take 81 away from 113, we end up with 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 81

Let's proceed to step 6:
328 divided by 81 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4914.0
If we subtract 324 from 328, we 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.

Let's proceed to step 7:
81 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 4914.0
Subtract 0 from 40 to get 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 8:
400 divided by 81 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 4914.04
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
760 divided by 81 is 9 with a remainder of 31.
The next digit of our result is 9. 
Result so far: 4914.049
If we subtract 729 from 760, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 10:
81 can be fit into 310 3 times, resulting in a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 4914.0493
If we take 243 away from 310, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 4914.04938
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
81 goes into 220 2 times with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 4914.049382
Deduct 162 from 220 and we're left 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.

On to step 13:
81 goes into 580 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 4914.0493827
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
130 divided by 81 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 4914.04938271
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Our division results in 4914.04938271 with a remaining 4.9e-08.
