We divide 10030172 by 432
We want to figure out the number of times 10030172 can be divided by 432.

Going ahead to step 1:
432 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 432

Advancing to step 2:
If we divide 10 by 432, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 432

Step 3:
100 divided by 432 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 100, we get 100.
Include the next digit (3) from the dividend after 100, then repeat: 1003 / 432

Let's proceed to step 4:
1003 divided by 432 is 2 with a remainder of 139.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 864 from 1003 leaves us with 139.
Include the next digit (0) from the dividend after 139, then repeat: 1390 / 432

Step 5:
1390 divided by 432 is 3 with a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 94 after subtracting 1296 from 1390.
Append the next digit (1) from the dividend to 94 and continue with: 941 / 432

Moving on to step 6:
If we divide 941 by 432, we get 2 and a remainder of 77.
Use 2 as the next digit of our solution. 
Result so far: 232.0
If we subtract 864 from 941, we get 77.
Bring next digit (7) of the dividend behind the 77 and repeat the process: 777 / 432

Moving on to step 7:
The number 432 fits into 777 1 times, leaving a remainder of 345.
Use 1 as the next digit of our solution. 
Result so far: 2321.0
The remainder is 345 after subtracting 432 from 777.
Include the next digit (2) from the dividend after 345, then repeat: 3452 / 432

On to step 8:
432 goes into 3452 7 times with a remainder of 428.
Write down 7 as next digit of the result. 
Result so far: 23217.0
Subtracting 3024 from 3452 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 9:
4280 divided by 432 is 9 with a remainder of 392.
Write down 9 as next digit of the result. 
Result so far: 23217.9
If we subtract 3888 from 4280, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 10:
432 can be fit into 3920 9 times, resulting in a remainder of 32.
Use 9 as the next digit of our solution. 
Result so far: 23217.99
Subtracting 3888 from 3920 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.

The final outcome is 23217.99, with a leftover of 0.032.
