We look at the division of 388241 by 81 
We want to figure out the number of times 388241 can be divided by 81.

On to step 1:
81 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 81

Step 2:
If we divide 38 by 81, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 81

Let's proceed to step 3:
The number 81 fits into 388 4 times, leaving a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 324 from 388, we get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 81

On to step 4:
81 can be fit into 642 7 times, resulting in a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 567 from 642 leaves us with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 81

Let's proceed to step 5:
When dividing 754 by 81, we get 9 with a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 479.0
Subtract 729 from 754 to get 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 81

Advancing to step 6:
81 can be fit into 251 3 times, resulting in a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 4793.0
The remainder is 8 after subtracting 243 from 251.
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 7:
The number 81 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4793.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
If we divide 800 by 81, we get 9 and a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 4793.09
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 9:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 4793.098
The remainder is 62 after subtracting 648 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
81 can be fit into 620 7 times, resulting in a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 4793.0987
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 11:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4793.09876
Deduct 486 from 530 and we're left 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 12:
81 goes into 440 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4793.098765
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
350 divided by 81 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 4793.0987654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 14:
When dividing 260 by 81, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 4793.09876543
Deduct 243 from 260 and we're left 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.

The final outcome is 4793.09876543, with a leftover of 1.7e-08.
