We look at the division of 28439013 by 453 
We want to figure out the number of times 28439013 can be divided by 453.

On to step 1:
When dividing 2 by 453, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 453

Moving on to step 2:
453 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 453

Moving on to step 3:
284 divided by 453 is 0 with a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 284 after subtracting 0 from 284.
Include the next digit (3) from the dividend after 284, then repeat: 2843 / 453

Advancing to step 4:
453 can be fit into 2843 6 times, resulting in a remainder of 125.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 2718 from 2843 to get 125.
Take the next digit (9) from the dividend and append it to 125, then repeat: 1259 / 453

Advancing to step 5:
453 goes into 1259 2 times with a remainder of 353.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 906 away from 1259, we end up with 353.
Grab the next digit (0) from the dividend, add it to 353, then carry on: 3530 / 453

Step 6:
3530 divided by 453 is 7 with a remainder of 359.
The number 7 becomes the next digit in our result. 
Result so far: 627.0
The remainder is 359 after subtracting 3171 from 3530.
Bring next digit (1) of the dividend behind the 359 and repeat the process: 3591 / 453

Step 7:
453 goes into 3591 7 times with a remainder of 420.
Use 7 as the next digit of our solution. 
Result so far: 6277.0
Subtracting 3171 from 3591 leaves us with 420.
Include the next digit (3) from the dividend after 420, then repeat: 4203 / 453

Advancing to step 8:
The number 453 fits into 4203 9 times, leaving a remainder of 126.
The number 9 becomes the next digit in our result. 
Result so far: 62779.0
If we take 4077 away from 4203, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 9:
453 can be fit into 1260 2 times, resulting in a remainder of 354.
Use 2 as the next digit of our solution. 
Result so far: 62779.2
Subtract 906 from 1260 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 10:
3540 divided by 453 is 7 with a remainder of 369.
Use 7 as the next digit of our solution. 
Result so far: 62779.27
If we take 3171 away from 3540, we end up with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

Step 11:
453 goes into 3690 8 times with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 62779.278
The remainder is 66 after subtracting 3624 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 12:
453 goes into 660 1 times with a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 62779.2781
If we subtract 453 from 660, we get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 13:
If we divide 2070 by 453, we get 4 and a remainder of 258.
Put 4 as the next digit of the answer. 
Result so far: 62779.27814
Subtract 1812 from 2070 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

On to step 14:
453 can be fit into 2580 5 times, resulting in a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 62779.278145
Subtract 2265 from 2580 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 15:
The number 453 fits into 3150 6 times, leaving a remainder of 432.
The next digit of our result is 6. 
Result so far: 62779.2781456
Subtract 2718 from 3150 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 16:
453 can be fit into 4320 9 times, resulting in a remainder of 243.
The number 9 becomes the next digit in our result. 
Result so far: 62779.27814569
The remainder is 243 after subtracting 4077 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Our division results in 62779.27814569 with a remaining 2.43e-07.
