We're dividing 378783 by 1 
We want to figure out the number of times 378783 can be divided by 1.

Going ahead to step 1:
When dividing 3 by 1, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 3 from 3, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Step 2:
1 goes into 7 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtracting 7 from 7 leaves us with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 3:
1 goes into 8 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 378.0
If we subtract 8 from 8, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Advancing to step 4:
When dividing 7 by 1, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 3787.0
If we take 7 away from 7, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Going ahead to step 5:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 37878.0
The remainder is 0 after subtracting 8 from 8.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Let's proceed to step 6:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 378783.0
If we subtract 3 from 3, 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:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 378783.0
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.

On to step 8:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 378783.0
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.

The quotient of the division is 378783.0, and the remainder is 0.0.
