432864 ÷ 81 
Let's see how many times 81 fits into 432864.

Step 1:
The number 81 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 81

Advancing to step 2:
The number 81 fits into 43 0 times, leaving a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 81

Going ahead to step 3:
81 goes into 432 5 times with a remainder of 27.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 405 from 432 to get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 81

Let's proceed to step 4:
278 divided by 81 is 3 with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Deduct 243 from 278 and we're left with 35.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 81

Advancing to step 5:
If we divide 356 by 81, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 534.0
Subtracting 324 from 356 leaves us with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 81

Going ahead to step 6:
When dividing 324 by 81, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 5344.0
If we take 324 away from 324, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
0 divided by 81 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5344.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
81 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5344.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 5344.0, and the remainder is 0.0.
