We look at the division of 788451 by 5 
We want to figure out the number of times 788451 can be divided by 5.

Let's proceed to step 1:
The number 5 fits into 7 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 5 from 7, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 5

Step 2:
If we divide 28 by 5, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 25 from 28 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 5

Going ahead to step 3:
38 divided by 5 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 157.0
If we take 35 away from 38, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 5

On to step 4:
5 goes into 34 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1576.0
Deduct 30 from 34 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 5

On to step 5:
5 can be fit into 45 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 15769.0
Subtracting 45 from 45 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 5

Moving on to step 6:
1 divided by 5 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 157690.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
5 can be fit into 10 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 157690.2
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
5 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 157690.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 5, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 157690.2
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 157690.2 with a remaining 0.0.
