2604637 ÷ 978 
Let's see how many times 978 fits into 2604637.

Step 1:
If we divide 2 by 978, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 978

On to step 2:
When dividing 26 by 978, we get 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Append the next digit (0) from the dividend to 26 and continue with: 260 / 978

Moving on to step 3:
When dividing 260 by 978, we get 0 with a remainder of 260.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 260 to get 260.
Append the next digit (4) from the dividend to 260 and continue with: 2604 / 978

Advancing to step 4:
If we divide 2604 by 978, we get 2 and a remainder of 648.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1956 from 2604 to get 648.
Grab the next digit (6) from the dividend, add it to 648, then carry on: 6486 / 978

On to step 5:
If we divide 6486 by 978, we get 6 and a remainder of 618.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 5868 from 6486 to get 618.
Fetch the next digit (3) from the dividend, attach it to 618 and continue: 6183 / 978

Going ahead to step 6:
When dividing 6183 by 978, we get 6 with a remainder of 315.
Use 6 as the next digit of our solution. 
Result so far: 266.0
Subtract 5868 from 6183 to get 315.
Include the next digit (7) from the dividend after 315, then repeat: 3157 / 978

Moving on to step 7:
If we divide 3157 by 978, we get 3 and a remainder of 223.
Use 3 as the next digit of our solution. 
Result so far: 2663.0
Subtracting 2934 from 3157 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 8:
The number 978 fits into 2230 2 times, leaving a remainder of 274.
Use 2 as the next digit of our solution. 
Result so far: 2663.2
If we take 1956 away from 2230, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 9:
978 goes into 2740 2 times with a remainder of 784.
Record the quotient 2 as the next digit in the result. 
Result so far: 2663.22
Subtract 1956 from 2740 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

After the division, we end up with 2663.22 and a remainder of 0.784.
