Let's divide 749970 by 1
We're looking to find how many times 1 goes into 749970.

On to step 1:
1 can be fit into 7 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Going ahead to step 2:
If we divide 4 by 1, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Step 3:
9 divided by 1 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 749.0
If we subtract 9 from 9, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

On to step 4:
If we divide 9 by 1, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 7499.0
If we subtract 9 from 9, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Let's proceed to step 5:
The number 1 fits into 7 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 74997.0
Deduct 7 from 7 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Going ahead to step 6:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 749970.0
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.

Let's proceed to step 7:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 749970.0
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.

Let's proceed to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 749970.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 749970.0 and a remainder of 0.0.
