We look at the division of 389497 by 81 
We want to divide 389497 by 81.

Step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 81

Moving on to step 2:
The number 81 fits into 38 0 times, leaving a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 81

Step 3:
81 can be fit into 389 4 times, resulting in a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 324 from 389 to get 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 81

On to step 4:
If we divide 654 by 81, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we subtract 648 from 654, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 81

Advancing to step 5:
If we divide 69 by 81, we get 0 and a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 480.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (7) from the dividend after 69, then repeat: 697 / 81

On to step 6:
81 goes into 697 8 times with a remainder of 49.
The next digit of our result is 8. 
Result so far: 4808.0
Deduct 648 from 697 and we're left 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.

Step 7:
When dividing 490 by 81, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 4808.6
If we subtract 486 from 490, 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.

Advancing to step 8:
81 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4808.6
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.

On to step 9:
The number 81 fits into 400 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4808.604
The remainder is 76 after subtracting 324 from 400.
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 10:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 4808.6049
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.

Let's proceed to step 11:
The number 81 fits into 310 3 times, leaving a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 4808.60493
If we subtract 243 from 310, 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.

Step 12:
When dividing 670 by 81, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 4808.604938
Subtracting 648 from 670 leaves us 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.

Step 13:
220 divided by 81 is 2 with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 4808.6049382
Subtract 162 from 220 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
580 divided by 81 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 4808.60493827
If we take 567 away from 580, we end up 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.

The quotient of the division is 4808.60493827, and the remainder is 1.3e-08.
