392194 ÷ 81 
We want to divide 392194 by 81.

Going ahead to step 1:
81 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 81

Let's proceed 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.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 81

On to step 3:
When dividing 392 by 81, we get 4 with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 324 away from 392, we end up with 68.
Bring next digit (1) of the dividend behind the 68 and repeat the process: 681 / 81

Let's proceed to step 4:
When dividing 681 by 81, we get 8 with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtract 648 from 681 to get 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 81

Advancing to step 5:
When dividing 339 by 81, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 484.0
Subtracting 324 from 339 leaves us with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 81

Advancing to step 6:
154 divided by 81 is 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 4841.0
If we take 81 away from 154, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
If we divide 730 by 81, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 4841.9
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
10 divided by 81 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4841.9
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
When dividing 100 by 81, we get 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 4841.901
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
The number 81 fits into 190 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 4841.9012
Deduct 162 from 190 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 11:
If we divide 280 by 81, we get 3 and a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 4841.90123
If we take 243 away from 280, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
When dividing 370 by 81, we get 4 with a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 4841.901234
Deduct 324 from 370 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 13:
81 can be fit into 460 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 4841.9012345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 14:
81 goes into 550 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 4841.90123456
Deduct 486 from 550 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 4841.90123456 and a remainder of 6.4e-08.
