Let's divide 123778 by 4
We're looking to find how many times 4 goes into 123778.

Going ahead to step 1:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 4

Advancing to step 2:
If we divide 12 by 4, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 12 from 12, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Let's proceed to step 3:
4 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 4

On to step 4:
When dividing 37 by 4, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 309.0
If we subtract 36 from 37, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 4

Going ahead to step 5:
When dividing 17 by 4, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 3094.0
If we subtract 16 from 17, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 4

Moving on to step 6:
4 goes into 18 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 30944.0
The remainder is 2 after subtracting 16 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 30944.5
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.

Moving on to step 8:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30944.5
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.

Moving on to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30944.5
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.

The final outcome is 30944.5, with a leftover of 0.0.
