Let's divide 74378 by 1
Let's see how many times 1 fits into 74378.

Advancing to step 1:
When dividing 7 by 1, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
If we take 7 away from 7, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Step 2:
4 divided by 1 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Subtract 4 from 4 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Moving on to step 3:
When dividing 3 by 1, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 743.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

On to step 4:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 7437.0
Subtracting 7 from 7 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Going ahead to step 5:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 74378.0
If we take 8 away from 8, 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.

Let's proceed to step 6:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 74378.0
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.

Let's proceed to step 7:
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: 74378.0
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 74378.0 and a remainder of 0.0.
