We divide 433664 by 81
Let's see how many times 81 fits into 433664.

Advancing to step 1:
81 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 81

Advancing to step 2:
43 divided by 81 is 0 with a remainder of 43.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (3) from the dividend to 43 and continue with: 433 / 81

On to step 3:
When dividing 433 by 81, we get 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 28 after subtracting 405 from 433.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 81

Let's proceed to step 4:
If we divide 286 by 81, we get 3 and a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 243 from 286 to get 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 81

Going ahead to step 5:
81 goes into 436 5 times with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 535.0
The remainder is 31 after subtracting 405 from 436.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 81

Advancing to step 6:
81 can be fit into 314 3 times, resulting in a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 5353.0
Subtracting 243 from 314 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 7:
When dividing 710 by 81, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 5353.8
Deduct 648 from 710 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
81 goes into 620 7 times with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 5353.87
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.

Moving on to step 9:
If we divide 530 by 81, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 5353.876
If we subtract 486 from 530, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
The number 81 fits into 440 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 5353.8765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 11:
If we divide 350 by 81, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 5353.87654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
81 goes into 260 3 times with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 5353.876543
The remainder is 17 after subtracting 243 from 260.
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 13:
81 can be fit into 170 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 5353.8765432
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.

Advancing to step 14:
When dividing 80 by 81, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 5353.8765432
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The quotient of the division is 5353.8765432, and the remainder is 8e-08.
