We're dividing 21519576 by 432 
We want to divide 21519576 by 432.

Going ahead to step 1:
432 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 432

Step 2:
The number 432 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 432

Moving on to step 3:
215 divided by 432 is 0 with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 215 leaves us with 215.
Take the next digit (1) from the dividend and append it to 215, then repeat: 2151 / 432

Going ahead to step 4:
432 can be fit into 2151 4 times, resulting in a remainder of 423.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 423 after subtracting 1728 from 2151.
Take the next digit (9) from the dividend and append it to 423, then repeat: 4239 / 432

Going ahead to step 5:
432 can be fit into 4239 9 times, resulting in a remainder of 351.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Deduct 3888 from 4239 and we're left with 351.
Take the next digit (5) from the dividend and append it to 351, then repeat: 3515 / 432

Step 6:
3515 divided by 432 is 8 with a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 498.0
The remainder is 59 after subtracting 3456 from 3515.
Bring next digit (7) of the dividend behind the 59 and repeat the process: 597 / 432

Moving on to step 7:
If we divide 597 by 432, we get 1 and a remainder of 165.
Write down 1 as next digit of the result. 
Result so far: 4981.0
The remainder is 165 after subtracting 432 from 597.
Grab the next digit (6) from the dividend, add it to 165, then carry on: 1656 / 432

Step 8:
432 can be fit into 1656 3 times, resulting in a remainder of 360.
Use 3 as the next digit of our solution. 
Result so far: 49813.0
Deduct 1296 from 1656 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 9:
432 goes into 3600 8 times with a remainder of 144.
Write down 8 as next digit of the result. 
Result so far: 49813.8
If we take 3456 away from 3600, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 10:
432 goes into 1440 3 times with a remainder of 144.
The number 3 becomes the next digit in our result. 
Result so far: 49813.83
Subtracting 1296 from 1440 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 11:
1440 divided by 432 is 3 with a remainder of 144.
Use 3 as the next digit of our solution. 
Result so far: 49813.833
Subtracting 1296 from 1440 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final result is 49813.833 with a remainder of 0.0144.
