457603 ÷ 28 
We're looking to find how many times 28 goes into 457603.

On to step 1:
28 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 28

On to step 2:
The number 28 fits into 45 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 28 from 45 and we're left with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 28

Moving on to step 3:
The number 28 fits into 177 6 times, leaving a remainder of 9.
The next digit of our result is 6. 
Result so far: 16.0
If we take 168 away from 177, we end up with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 28

On to step 4:
If we divide 96 by 28, we get 3 and a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 163.0
If we take 84 away from 96, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 28

On to step 5:
When dividing 120 by 28, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 1634.0
If we take 112 away from 120, we end up with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 28

Step 6:
28 can be fit into 83 2 times, resulting in a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 16342.0
If we subtract 56 from 83, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
270 divided by 28 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 16342.9
If we subtract 252 from 270, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
28 can be fit into 180 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 16342.96
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 16342.964
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 28 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 16342.9642
Subtracting 56 from 80 leaves us with 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 11:
The number 28 fits into 240 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 16342.96428
If we subtract 224 from 240, we 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.

On to step 12:
28 goes into 160 5 times with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 16342.964285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 16342.9642857
If we subtract 196 from 200, we 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.

Moving on to step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 16342.96428571
Subtracting 28 from 40 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 16342.96428571, with a leftover of 1.2e-08.
