We're dividing 365129 by 81 
We're looking to find how many times 81 goes into 365129.

Step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 81

Let's proceed to step 2:
36 divided by 81 is 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 81

Let's proceed to step 3:
When dividing 365 by 81, we get 4 with a remainder of 41.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 324 from 365 leaves us with 41.
Append the next digit (1) from the dividend to 41 and continue with: 411 / 81

Going ahead to step 4:
The number 81 fits into 411 5 times, leaving a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 405 away from 411, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 81

On to step 5:
If we divide 62 by 81, we get 0 and a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 450.0
If we take 0 away from 62, we end up with 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 81

Let's proceed to step 6:
629 divided by 81 is 7 with a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 4507.0
Subtract 567 from 629 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
The number 81 fits into 620 7 times, leaving a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 4507.7
Subtract 567 from 620 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 8:
530 divided by 81 is 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 4507.76
Subtracting 486 from 530 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 81, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 4507.765
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
81 goes into 350 4 times with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 4507.7654
Subtract 324 from 350 to get 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 11:
81 can be fit into 260 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 4507.76543
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
81 goes into 170 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 4507.765432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
If we divide 80 by 81, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 4507.765432
The remainder is 80 after subtracting 0 from 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 14:
81 goes into 800 9 times with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 4507.76543209
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final result is 4507.76543209 with a remainder of 7.1e-08.
