375239 ÷ 81 
Let's see how many times 81 fits into 375239.

On to step 1:
81 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 81

Advancing to step 2:
The number 81 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 81

Let's proceed to step 3:
375 divided by 81 is 4 with a remainder of 51.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 324 from 375 leaves us with 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 81

Step 4:
81 can be fit into 512 6 times, resulting in a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
The remainder is 26 after subtracting 486 from 512.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 81

On to step 5:
The number 81 fits into 263 3 times, leaving a remainder of 20.
The next digit of our result is 3. 
Result so far: 463.0
The remainder is 20 after subtracting 243 from 263.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 81

Going ahead to step 6:
If we divide 209 by 81, we get 2 and a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 4632.0
Deduct 162 from 209 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 4632.5
Subtracting 405 from 470 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
When dividing 650 by 81, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 4632.58
If we subtract 648 from 650, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
If we divide 20 by 81, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4632.58
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
If we divide 200 by 81, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 4632.5802
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
81 can be fit into 380 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 4632.58024
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
The number 81 fits into 560 6 times, leaving a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 4632.580246
If we take 486 away from 560, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 13:
81 can be fit into 740 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 4632.5802469
The remainder is 11 after subtracting 729 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
110 divided by 81 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 4632.58024691
Subtract 81 from 110 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

After the division, we end up with 4632.58024691 and a remainder of 2.9e-08.
