We divide 543432 by 28
We want to figure out the number of times 543432 can be divided by 28.

Step 1:
The number 28 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 28

Advancing to step 2:
If we divide 54 by 28, we get 1 and a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 28 from 54 and we're left with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 28

On to step 3:
If we divide 263 by 28, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 252 from 263 and we're left with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 28

Going ahead to step 4:
114 divided by 28 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 194.0
Deduct 112 from 114 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 28

Moving on to step 5:
28 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 1940.0
The remainder is 23 after subtracting 0 from 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 28

Step 6:
If we divide 232 by 28, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 19408.0
If we take 224 away from 232, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
28 goes into 80 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 19408.2
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 19408.28
Subtracting 224 from 240 leaves us 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.

Step 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 19408.285
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 19408.2857
Subtract 196 from 200 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 19408.28571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 19408.285714
Subtracting 112 from 120 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 19408.2857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 19408.28571428
Subtract 224 from 240 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.

The final outcome is 19408.28571428, with a leftover of 1.6e-08.
