28402639 divided by 672 
We want to figure out the number of times 28402639 can be divided by 672.

Step 1:
672 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 672

Going ahead to step 2:
The number 672 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 672

Let's proceed to step 3:
672 goes into 284 0 times with a remainder of 284.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 284 leaves us with 284.
Fetch the next digit (0) from the dividend, attach it to 284 and continue: 2840 / 672

On to step 4:
2840 divided by 672 is 4 with a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2688 away from 2840, we end up with 152.
Append the next digit (2) from the dividend to 152 and continue with: 1522 / 672

Moving on to step 5:
1522 divided by 672 is 2 with a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 1344 from 1522 and we're left with 178.
Append the next digit (6) from the dividend to 178 and continue with: 1786 / 672

Let's proceed to step 6:
When dividing 1786 by 672, we get 2 with a remainder of 442.
Record the quotient 2 as the next digit in the result. 
Result so far: 422.0
If we take 1344 away from 1786, we end up with 442.
Include the next digit (3) from the dividend after 442, then repeat: 4423 / 672

On to step 7:
When dividing 4423 by 672, we get 6 with a remainder of 391.
The number 6 becomes the next digit in our result. 
Result so far: 4226.0
If we take 4032 away from 4423, we end up with 391.
Bring next digit (9) of the dividend behind the 391 and repeat the process: 3919 / 672

Let's proceed to step 8:
The number 672 fits into 3919 5 times, leaving a remainder of 559.
Put 5 as the next digit of the answer. 
Result so far: 42265.0
The remainder is 559 after subtracting 3360 from 3919.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Moving on to step 9:
If we divide 5590 by 672, we get 8 and a remainder of 214.
Record the quotient 8 as the next digit in the result. 
Result so far: 42265.8
If we subtract 5376 from 5590, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 10:
The number 672 fits into 2140 3 times, leaving a remainder of 124.
Write down 3 as next digit of the result. 
Result so far: 42265.83
Deduct 2016 from 2140 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 11:
The number 672 fits into 1240 1 times, leaving a remainder of 568.
Record the quotient 1 as the next digit in the result. 
Result so far: 42265.831
Subtract 672 from 1240 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 12:
When dividing 5680 by 672, we get 8 with a remainder of 304.
The number 8 becomes the next digit in our result. 
Result so far: 42265.8318
Subtract 5376 from 5680 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 13:
If we divide 3040 by 672, we get 4 and a remainder of 352.
Use 4 as the next digit of our solution. 
Result so far: 42265.83184
Subtract 2688 from 3040 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 14:
The number 672 fits into 3520 5 times, leaving a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 42265.831845
The remainder is 160 after subtracting 3360 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
1600 divided by 672 is 2 with a remainder of 256.
Put 2 as the next digit of the answer. 
Result so far: 42265.8318452
If we subtract 1344 from 1600, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
The number 672 fits into 2560 3 times, leaving a remainder of 544.
The number 3 becomes the next digit in our result. 
Result so far: 42265.83184523
Subtract 2016 from 2560 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

After the division, we end up with 42265.83184523 and a remainder of 5.44e-07.
