385665 ÷ 81 
We're looking to find how many times 81 goes into 385665.

Let's proceed 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.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 81

On to step 2:
The number 81 fits into 38 0 times, leaving a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 81

Let's proceed to step 3:
385 divided by 81 is 4 with a remainder of 61.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 324 from 385, we get 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 81

Step 4:
If we divide 616 by 81, we get 7 and a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 567 from 616 leaves us with 49.
Include the next digit (6) from the dividend after 49, then repeat: 496 / 81

Advancing to step 5:
The number 81 fits into 496 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 476.0
If we take 486 away from 496, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 81

On to step 6:
The number 81 fits into 105 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 4761.0
Deduct 81 from 105 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
If we divide 240 by 81, we get 2 and a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 4761.2
Deduct 162 from 240 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 8:
If we divide 780 by 81, we get 9 and a remainder of 51.
The next digit of our result is 9. 
Result so far: 4761.29
If we subtract 729 from 780, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
If we divide 510 by 81, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 4761.296
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
The number 81 fits into 240 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 4761.2962
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 4761.29629
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 12:
If we divide 510 by 81, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 4761.296296
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
240 divided by 81 is 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 4761.2962962
Subtract 162 from 240 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
When dividing 780 by 81, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 4761.29629629
If we take 729 away from 780, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 4761.29629629 with a remainder of 5.1e-08.
