We look at the division of 4385509 by 432 
We want to figure out the number of times 4385509 can be divided by 432.

Moving on to step 1:
The number 432 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 432

Advancing to step 2:
If we divide 43 by 432, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Include the next digit (8) from the dividend after 43, then repeat: 438 / 432

Let's proceed to step 3:
438 divided by 432 is 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 432 from 438, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 432

Let's proceed to step 4:
When dividing 65 by 432, we get 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 65, we end up with 65.
Grab the next digit (5) from the dividend, add it to 65, then carry on: 655 / 432

Moving on to step 5:
When dividing 655 by 432, we get 1 with a remainder of 223.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 432 from 655 leaves us with 223.
Bring next digit (0) of the dividend behind the 223 and repeat the process: 2230 / 432

Moving on to step 6:
If we divide 2230 by 432, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 1015.0
If we subtract 2160 from 2230, we get 70.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 432

Advancing to step 7:
If we divide 709 by 432, we get 1 and a remainder of 277.
The next digit of our result is 1. 
Result so far: 10151.0
Subtract 432 from 709 to get 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

Step 8:
432 goes into 2770 6 times with a remainder of 178.
Record the quotient 6 as the next digit in the result. 
Result so far: 10151.6
Deduct 2592 from 2770 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 9:
432 can be fit into 1780 4 times, resulting in a remainder of 52.
The next digit of our result is 4. 
Result so far: 10151.64
Deduct 1728 from 1780 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
When dividing 520 by 432, we get 1 with a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 10151.641
The remainder is 88 after subtracting 432 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
If we divide 880 by 432, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 10151.6412
Subtract 864 from 880 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
When dividing 160 by 432, we get 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 10151.6412
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
When dividing 1600 by 432, we get 3 with a remainder of 304.
Put 3 as the next digit of the answer. 
Result so far: 10151.641203
If we take 1296 away from 1600, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 14:
432 goes into 3040 7 times with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 10151.6412037
If we take 3024 away from 3040, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 15:
432 can be fit into 160 0 times, resulting in a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 10151.6412037
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Our division results in 10151.6412037 with a remaining 1.6e-07.
