We're dividing 381392 by 81 
We're looking to find how many times 81 goes into 381392.

On to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
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

Advancing 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
If we take 0 away from 38, we end up with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 81

Advancing to step 3:
81 can be fit into 381 4 times, resulting in a remainder of 57.
The next digit of our result is 4. 
Result so far: 4.0
If we take 324 away from 381, we end up with 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 81

On to step 4:
81 goes into 573 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we take 567 away from 573, we end up with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 81

Step 5:
81 goes into 69 0 times with a remainder of 69.
Record the quotient 0 as the next digit in the result. 
Result so far: 470.0
If we take 0 away from 69, we end up with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 81

Moving on to step 6:
81 can be fit into 692 8 times, resulting in a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 4708.0
If we subtract 648 from 692, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
When dividing 440 by 81, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4708.5
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
81 goes into 350 4 times with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 4708.54
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
When dividing 260 by 81, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 4708.543
Subtracting 243 from 260 leaves us 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.

Let's proceed to step 10:
If we divide 170 by 81, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 4708.5432
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 81, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4708.5432
Subtract 0 from 80 to get 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 12:
81 can be fit into 800 9 times, resulting in a remainder of 71.
The next digit of our result is 9. 
Result so far: 4708.543209
Deduct 729 from 800 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 13:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 4708.5432098
Subtracting 648 from 710 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
81 can be fit into 620 7 times, resulting in a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 4708.54320987
Deduct 567 from 620 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 4708.54320987 and a remainder of 5.3e-08.
