13090561 ÷ 432 
We're looking to find how many times 432 goes into 13090561.

On to step 1:
The number 432 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 432

Advancing to step 2:
432 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 432

Let's proceed to step 3:
The number 432 fits into 130 0 times, leaving a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 130 leaves us with 130.
Grab the next digit (9) from the dividend, add it to 130, then carry on: 1309 / 432

Advancing to step 4:
1309 divided by 432 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1296 from 1309, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 432

On to step 5:
130 divided by 432 is 0 with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 130, we end up with 130.
Include the next digit (5) from the dividend after 130, then repeat: 1305 / 432

Going ahead to step 6:
If we divide 1305 by 432, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 303.0
Deduct 1296 from 1305 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 432

Going ahead to step 7:
The number 432 fits into 96 0 times, leaving a remainder of 96.
Put 0 as the next digit of the answer. 
Result so far: 3030.0
If we subtract 0 from 96, we get 96.
Include the next digit (1) from the dividend after 96, then repeat: 961 / 432

Let's proceed to step 8:
432 can be fit into 961 2 times, resulting in a remainder of 97.
Put 2 as the next digit of the answer. 
Result so far: 30302.0
If we subtract 864 from 961, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
432 can be fit into 970 2 times, resulting in a remainder of 106.
Use 2 as the next digit of our solution. 
Result so far: 30302.2
Subtract 864 from 970 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 10:
When dividing 1060 by 432, we get 2 with a remainder of 196.
Put 2 as the next digit of the answer. 
Result so far: 30302.22
The remainder is 196 after subtracting 864 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final outcome is 30302.22, with a leftover of 0.196.
