The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 432

Moving on to step 2:
When dividing 39 by 432, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 432

Let's proceed to step 3:
432 goes into 391 0 times with a remainder of 391.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 391 and we're left with 391.
Take the next digit (2) from the dividend and append it to 391, then repeat: 3912 / 432

Going ahead to step 4:
When dividing 3912 by 432, we get 9 with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 3888 from 3912 and we're left with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 432

Let's proceed to step 5:
The number 432 fits into 249 0 times, leaving a remainder of 249.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 249, we get 249.
Grab the next digit (2) from the dividend, add it to 249, then carry on: 2492 / 432

Let's proceed to step 6:
The number 432 fits into 2492 5 times, leaving a remainder of 332.
The number 5 becomes the next digit in our result. 
Result so far: 905.0
Deduct 2160 from 2492 and we're left with 332.
Include the next digit (9) from the dividend after 332, then repeat: 3329 / 432

Step 7:
If we divide 3329 by 432, we get 7 and a remainder of 305.
The number 7 becomes the next digit in our result. 
Result so far: 9057.0
Subtract 3024 from 3329 to get 305.
Take the next digit (6) from the dividend and append it to 305, then repeat: 3056 / 432

Let's proceed to step 8:
3056 divided by 432 is 7 with a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 90577.0
If we subtract 3024 from 3056, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
432 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 90577.0
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
3200 divided by 432 is 7 with a remainder of 176.
Write down 7 as next digit of the result. 
Result so far: 90577.07
Subtract 3024 from 3200 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
432 can be fit into 1760 4 times, resulting in a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 90577.074
Subtracting 1728 from 1760 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
432 goes into 320 0 times with a remainder of 320.
The next digit of our result is 0. 
Result so far: 90577.074
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
432 can be fit into 3200 7 times, resulting in a remainder of 176.
Put 7 as the next digit of the answer. 
Result so far: 90577.07407
If we subtract 3024 from 3200, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 14:
The number 432 fits into 1760 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 90577.074074
Subtract 1728 from 1760 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 15:
432 can be fit into 320 0 times, resulting in a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 90577.074074
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 16:
3200 divided by 432 is 7 with a remainder of 176.
Record the quotient 7 as the next digit in the result. 
Result so far: 90577.07407407
The remainder is 176 after subtracting 3024 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Our division results in 90577.07407407 with a remaining 1.76e-07.
