We divide 678470 by 28
We want to figure out the number of times 678470 can be divided by 28.

Advancing to step 1:
28 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 28

Let's proceed to step 2:
If we divide 67 by 28, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 11 after subtracting 56 from 67.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 28

Moving on to step 3:
28 goes into 118 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 112 from 118, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 28

Moving on to step 4:
28 can be fit into 64 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 242.0
The remainder is 8 after subtracting 56 from 64.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 28

Let's proceed to step 5:
When dividing 87 by 28, we get 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 2423.0
Subtracting 84 from 87 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 28

On to step 6:
30 divided by 28 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 24231.0
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 28, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 24231.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 24231.07
Subtracting 196 from 200 leaves us 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.

Going ahead to step 9:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 24231.071
If we subtract 28 from 40, we 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 10:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 24231.0714
If we take 112 away from 120, we end up 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 11:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 24231.07142
Subtract 56 from 80 to 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.

Step 12:
If we divide 240 by 28, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 24231.071428
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.

Going ahead to step 13:
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: 24231.0714285
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
If we divide 200 by 28, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 24231.07142857
Subtracting 196 from 200 leaves us 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.

The quotient of the division is 24231.07142857, and the remainder is 4e-09.
