We're dividing 780103 by 4 
Let's see how many times 4 fits into 780103.

Moving on to step 1:
The number 4 fits into 7 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 4 from 7 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 4

Let's proceed to step 2:
When dividing 38 by 4, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 2 after subtracting 36 from 38.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 4

Let's proceed to step 3:
When dividing 20 by 4, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 195.0
Subtracting 20 from 20 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 4

Advancing to step 4:
1 divided by 4 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 1950.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 4

Step 5:
4 can be fit into 10 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 19502.0
The remainder is 2 after subtracting 8 from 10.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 4

Advancing to step 6:
When dividing 23 by 4, we get 5 with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 195025.0
The remainder is 3 after subtracting 20 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 195025.7
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 195025.75
Deduct 20 from 20 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.

Going ahead to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 195025.75
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 10:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 195025.75
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 final outcome is 195025.75, with a leftover of 0.0.
