We look at the division of 178470 by 285 
We want to figure out the number of times 178470 can be divided by 285.

Step 1:
If we divide 1 by 285, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 285

Going ahead to step 2:
If we divide 17 by 285, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 285

Advancing to step 3:
285 can be fit into 178 0 times, resulting in a remainder of 178.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 178, we end up with 178.
Include the next digit (4) from the dividend after 178, then repeat: 1784 / 285

Let's proceed to step 4:
The number 285 fits into 1784 6 times, leaving a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 1710 from 1784, we get 74.
Bring next digit (7) of the dividend behind the 74 and repeat the process: 747 / 285

Let's proceed to step 5:
285 goes into 747 2 times with a remainder of 177.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we take 570 away from 747, we end up with 177.
Take the next digit (0) from the dividend and append it to 177, then repeat: 1770 / 285

Going ahead to step 6:
The number 285 fits into 1770 6 times, leaving a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 626.0
The remainder is 60 after subtracting 1710 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
When dividing 600 by 285, we get 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 626.2
The remainder is 30 after subtracting 570 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
285 can be fit into 300 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 626.21
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
When dividing 150 by 285, we get 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 626.21
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
285 goes into 1500 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 626.2105
Subtract 1425 from 1500 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
285 goes into 750 2 times with a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 626.21052
If we take 570 away from 750, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 12:
When dividing 1800 by 285, we get 6 with a remainder of 90.
The next digit of our result is 6. 
Result so far: 626.210526
If we take 1710 away from 1800, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 13:
When dividing 900 by 285, we get 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 626.2105263
Subtract 855 from 900 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
450 divided by 285 is 1 with a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 626.21052631
Subtract 285 from 450 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final result is 626.21052631 with a remainder of 1.65e-07.
