Let's divide 392919 by 81
We're looking to find how many times 81 goes into 392919.

On to step 1:
If we divide 3 by 81, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 81

Let's proceed to step 2:
81 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 81

Let's proceed to step 3:
81 goes into 392 4 times with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 324 from 392 and we're left with 68.
Include the next digit (9) from the dividend after 68, then repeat: 689 / 81

Moving on to step 4:
81 goes into 689 8 times with a remainder of 41.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 648 from 689 and we're left with 41.
Fetch the next digit (1) from the dividend, attach it to 41 and continue: 411 / 81

Advancing to step 5:
81 can be fit into 411 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 485.0
If we subtract 405 from 411, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 81

Moving on to step 6:
69 divided by 81 is 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 4850.0
The remainder is 69 after subtracting 0 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
The number 81 fits into 690 8 times, leaving a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 4850.8
Deduct 648 from 690 and we're left 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 8:
When dividing 420 by 81, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 4850.85
If we subtract 405 from 420, we get 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 9:
If we divide 150 by 81, we get 1 and a remainder of 69.
The next digit of our result is 1. 
Result so far: 4850.851
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.

On to step 10:
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: 4850.8518
If we take 648 away from 690, we end up 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.

Step 11:
When dividing 420 by 81, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 4850.85185
If we take 405 away from 420, we end up 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 12:
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: 4850.851851
If we take 81 away from 150, 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 13:
81 goes into 690 8 times with a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 4850.8518518
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.

Going ahead to step 14:
When dividing 420 by 81, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 4850.85185185
If we take 405 away from 420, we end up 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 4850.85185185 with a remaining 1.5e-08.
