We're dividing 749909 by 5 
We want to figure out the number of times 749909 can be divided by 5.

Advancing to step 1:
5 can be fit into 7 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 5 from 7.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 5

Moving on to step 2:
If we divide 24 by 5, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 20 from 24 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 5

Step 3:
The number 5 fits into 49 9 times, leaving a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
If we subtract 45 from 49, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 5

Advancing to step 4:
If we divide 49 by 5, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 1499.0
Deduct 45 from 49 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 5

On to step 5:
40 divided by 5 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 14998.0
If we take 40 away from 40, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 5

Let's proceed to step 6:
The number 5 fits into 9 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 149981.0
If we subtract 5 from 9, we get 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 7:
5 goes into 40 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 149981.8
Deduct 40 from 40 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.

On to step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 149981.8
Deduct 0 from 0 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 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 149981.8
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.

Our division results in 149981.8 with a remaining 0.0.
