783978 ÷ 26 
We're looking to find how many times 26 goes into 783978.

Going ahead to step 1:
If we divide 7 by 26, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 26

Moving on to step 2:
26 goes into 78 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 78 from 78 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 26

On to step 3:
3 divided by 26 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 26

On to step 4:
26 goes into 39 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 301.0
The remainder is 13 after subtracting 26 from 39.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 26

Step 5:
When dividing 137 by 26, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 3015.0
The remainder is 7 after subtracting 130 from 137.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 26

Advancing to step 6:
26 can be fit into 78 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 30153.0
If we take 78 away from 78, 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 7:
26 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30153.0
Deduct 0 from 0 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.

Advancing to step 8:
26 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30153.0
If we take 0 away from 0, 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.

The final result is 30153.0 with a remainder of 0.0.
