We look at the division of 151605 by 5 
We want to figure out the number of times 151605 can be divided by 5.

On to step 1:
1 divided by 5 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 5

On to step 2:
If we divide 15 by 5, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 15 away from 15, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 5

Going ahead to step 3:
When dividing 1 by 5, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 5

Going ahead to step 4:
16 divided by 5 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 303.0
Deduct 15 from 16 and we're left with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 5

Step 5:
5 goes into 10 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 3032.0
Subtracting 10 from 10 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 5

Going ahead to step 6:
5 goes into 5 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 30321.0
Deduct 5 from 5 and we're left 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.

Step 7:
When dividing 0 by 5, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30321.0
Subtract 0 from 0 to 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.

On to step 8:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30321.0
Subtracting 0 from 0 leaves us 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.

The final outcome is 30321.0, with a leftover of 0.0.
