We divide 25021815 by 978
We want to figure out the number of times 25021815 can be divided by 978.

On to step 1:
The number 978 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 978

Let's proceed to step 2:
The number 978 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 978

Moving on to step 3:
When dividing 250 by 978, we get 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 250 to get 250.
Take the next digit (2) from the dividend and append it to 250, then repeat: 2502 / 978

Step 4:
2502 divided by 978 is 2 with a remainder of 546.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1956 away from 2502, we end up with 546.
Grab the next digit (1) from the dividend, add it to 546, then carry on: 5461 / 978

Advancing to step 5:
5461 divided by 978 is 5 with a remainder of 571.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 4890 from 5461 and we're left with 571.
Append the next digit (8) from the dividend to 571 and continue with: 5718 / 978

Moving on to step 6:
978 can be fit into 5718 5 times, resulting in a remainder of 828.
The next digit of our result is 5. 
Result so far: 255.0
Subtract 4890 from 5718 to get 828.
Bring next digit (1) of the dividend behind the 828 and repeat the process: 8281 / 978

Step 7:
The number 978 fits into 8281 8 times, leaving a remainder of 457.
The next digit of our result is 8. 
Result so far: 2558.0
Subtract 7824 from 8281 to get 457.
Grab the next digit (5) from the dividend, add it to 457, then carry on: 4575 / 978

Moving on to step 8:
978 can be fit into 4575 4 times, resulting in a remainder of 663.
Write down 4 as next digit of the result. 
Result so far: 25584.0
Subtract 3912 from 4575 to get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

On to step 9:
978 can be fit into 6630 6 times, resulting in a remainder of 762.
The number 6 becomes the next digit in our result. 
Result so far: 25584.6
Subtracting 5868 from 6630 leaves us with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Going ahead to step 10:
If we divide 7620 by 978, we get 7 and a remainder of 774.
Record the quotient 7 as the next digit in the result. 
Result so far: 25584.67
Deduct 6846 from 7620 and we're left with 774.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7740, and continue the process.

On to step 11:
If we divide 7740 by 978, we get 7 and a remainder of 894.
Write down 7 as next digit of the result. 
Result so far: 25584.677
If we subtract 6846 from 7740, we get 894.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8940, and continue the process.

After the division, we end up with 25584.677 and a remainder of 0.0894.
