We look at the division of 49398 by 81 
We want to figure out the number of times 49398 can be divided by 81.

Step 1:
4 divided by 81 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 81

On to step 2:
49 divided by 81 is 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Include the next digit (3) from the dividend after 49, then repeat: 493 / 81

On to step 3:
When dividing 493 by 81, we get 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 486 from 493 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 81

Step 4:
If we divide 79 by 81, we get 0 and a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtracting 0 from 79 leaves us with 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 81

Advancing to step 5:
81 can be fit into 798 9 times, resulting in a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 609.0
If we take 729 away from 798, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 6:
690 divided by 81 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 609.8
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 7:
The number 81 fits into 420 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 609.85
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
The number 81 fits into 150 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 609.851
The remainder is 69 after subtracting 81 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
81 goes into 690 8 times with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 609.8518
Subtracting 648 from 690 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
420 divided by 81 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 609.85185
Subtracting 405 from 420 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
81 can be fit into 150 1 times, resulting in a remainder of 69.
The next digit of our result is 1. 
Result so far: 609.851851
Deduct 81 from 150 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 12:
If we divide 690 by 81, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 609.8518518
Subtract 648 from 690 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
81 goes into 420 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 609.85185185
Deduct 405 from 420 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Our division results in 609.85185185 with a remaining 1.5e-08.
