674430 ÷ 28 
We're looking to find how many times 28 goes into 674430.

Step 1:
If we divide 6 by 28, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 28

Let's proceed to step 2:
28 goes into 67 2 times with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 56 from 67 leaves us with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 28

Going ahead to step 3:
114 divided by 28 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 112 from 114, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 28

Advancing to step 4:
When dividing 24 by 28, we get 0 with a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 240.0
The remainder is 24 after subtracting 0 from 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 28

Moving on to step 5:
The number 28 fits into 243 8 times, leaving a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 2408.0
If we subtract 224 from 243, we get 19.
Append the next digit (0) from the dividend to 19 and continue with: 190 / 28

Going ahead to step 6:
28 goes into 190 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 24086.0
If we subtract 168 from 190, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
28 can be fit into 220 7 times, resulting in a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 24086.7
If we take 196 away from 220, we end up 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 8:
If we divide 240 by 28, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 24086.78
If we take 224 away from 240, we end up 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.

Going ahead to step 9:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 24086.785
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 10:
If we divide 200 by 28, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 24086.7857
If we take 196 away from 200, we end up 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 11:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 24086.78571
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.

Moving on to step 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 24086.785714
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.

On to step 13:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 24086.7857142
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.

Let's proceed to step 14:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 24086.78571428
Deduct 224 from 240 and we're left 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.

After the division, we end up with 24086.78571428 and a remainder of 1.6e-08.
