748640 ÷ 28 
We want to figure out the number of times 748640 can be divided by 28.

On to step 1:
28 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 28

Advancing to step 2:
If we divide 74 by 28, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 56 from 74 leaves us with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 28

Step 3:
When dividing 188 by 28, we get 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Deduct 168 from 188 and we're left with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 28

Advancing to step 4:
28 can be fit into 206 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 267.0
Subtracting 196 from 206 leaves us with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 28

On to step 5:
If we divide 104 by 28, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 2673.0
Deduct 84 from 104 and we're left with 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 28

Moving on to step 6:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 26737.0
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 28, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 26737.1
Subtract 28 from 40 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.

On to step 8:
28 goes into 120 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 26737.14
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 26737.142
If we subtract 56 from 80, we 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.

Going ahead to step 10:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 26737.1428
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.

Let's proceed to step 11:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 26737.14285
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.

On to step 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 26737.142857
Deduct 196 from 200 and we're left with 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 13:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 26737.1428571
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.

Step 14:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 26737.14285714
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 26737.14285714 with a remaining 8e-09.
