We're dividing 66543108 by 432 
We're looking to find how many times 432 goes into 66543108.

Advancing to step 1:
The number 432 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 432

Moving on to step 2:
When dividing 66 by 432, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 432

Going ahead to step 3:
432 goes into 665 1 times with a remainder of 233.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 432 from 665 leaves us with 233.
Take the next digit (4) from the dividend and append it to 233, then repeat: 2334 / 432

Step 4:
432 can be fit into 2334 5 times, resulting in a remainder of 174.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2160 away from 2334, we end up with 174.
Take the next digit (3) from the dividend and append it to 174, then repeat: 1743 / 432

Let's proceed to step 5:
432 goes into 1743 4 times with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 154.0
If we subtract 1728 from 1743, we get 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 432

Let's proceed to step 6:
432 goes into 151 0 times with a remainder of 151.
The next digit of our result is 0. 
Result so far: 1540.0
Subtracting 0 from 151 leaves us with 151.
Include the next digit (0) from the dividend after 151, then repeat: 1510 / 432

On to step 7:
If we divide 1510 by 432, we get 3 and a remainder of 214.
Put 3 as the next digit of the answer. 
Result so far: 15403.0
Subtracting 1296 from 1510 leaves us with 214.
Bring next digit (8) of the dividend behind the 214 and repeat the process: 2148 / 432

On to step 8:
2148 divided by 432 is 4 with a remainder of 420.
The number 4 becomes the next digit in our result. 
Result so far: 154034.0
Subtracting 1728 from 2148 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 9:
432 goes into 4200 9 times with a remainder of 312.
Use 9 as the next digit of our solution. 
Result so far: 154034.9
Deduct 3888 from 4200 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 10:
432 can be fit into 3120 7 times, resulting in a remainder of 96.
Record the quotient 7 as the next digit in the result. 
Result so far: 154034.97
The remainder is 96 after subtracting 3024 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 11:
When dividing 960 by 432, we get 2 with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 154034.972
The remainder is 96 after subtracting 864 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
The number 432 fits into 960 2 times, leaving a remainder of 96.
Put 2 as the next digit of the answer. 
Result so far: 154034.9722
Deduct 864 from 960 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 154034.9722 with a remaining 0.00096.
