We're dividing 66556171 by 432 
We want to figure out the number of times 66556171 can be divided by 432.

On to step 1:
432 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 432

Let's proceed to step 2:
The number 432 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 432

On to step 3:
665 divided by 432 is 1 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.
Append the next digit (5) from the dividend to 233 and continue with: 2335 / 432

Step 4:
If we divide 2335 by 432, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2160 from 2335, we get 175.
Bring next digit (6) of the dividend behind the 175 and repeat the process: 1756 / 432

Moving on to step 5:
If we divide 1756 by 432, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
The remainder is 28 after subtracting 1728 from 1756.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 432

Advancing to step 6:
The number 432 fits into 281 0 times, leaving a remainder of 281.
Use 0 as the next digit of our solution. 
Result so far: 1540.0
Deduct 0 from 281 and we're left with 281.
Fetch the next digit (7) from the dividend, attach it to 281 and continue: 2817 / 432

Advancing to step 7:
When dividing 2817 by 432, we get 6 with a remainder of 225.
Put 6 as the next digit of the answer. 
Result so far: 15406.0
If we subtract 2592 from 2817, we get 225.
Bring next digit (1) of the dividend behind the 225 and repeat the process: 2251 / 432

Moving on to step 8:
When dividing 2251 by 432, we get 5 with a remainder of 91.
Write down 5 as next digit of the result. 
Result so far: 154065.0
Subtracting 2160 from 2251 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Step 9:
When dividing 910 by 432, we get 2 with a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 154065.2
Deduct 864 from 910 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
460 divided by 432 is 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 154065.21
The remainder is 28 after subtracting 432 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
If we divide 280 by 432, we get 0 and a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 154065.21
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 12:
The number 432 fits into 2800 6 times, leaving a remainder of 208.
The number 6 becomes the next digit in our result. 
Result so far: 154065.2106
Subtract 2592 from 2800 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 13:
If we divide 2080 by 432, we get 4 and a remainder of 352.
Write down 4 as next digit of the result. 
Result so far: 154065.21064
Subtract 1728 from 2080 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
432 can be fit into 3520 8 times, resulting in a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 154065.210648
If we take 3456 away from 3520, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
When dividing 640 by 432, we get 1 with a remainder of 208.
The number 1 becomes the next digit in our result. 
Result so far: 154065.2106481
If we take 432 away from 640, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 16:
If we divide 2080 by 432, we get 4 and a remainder of 352.
Write down 4 as next digit of the result. 
Result so far: 154065.21064814
Subtract 1728 from 2080 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

In conclusion, the division gives 154065.21064814 with a balance of 3.52e-07.
