We're dividing 25163962 by 980 
Let's see how many times 980 fits into 25163962.

Step 1:
When dividing 2 by 980, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 980

Going ahead to step 2:
The number 980 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 980

Advancing to step 3:
When dividing 251 by 980, we get 0 with a remainder of 251.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 251 and we're left with 251.
Grab the next digit (6) from the dividend, add it to 251, then carry on: 2516 / 980

Let's proceed to step 4:
2516 divided by 980 is 2 with a remainder of 556.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1960 from 2516 to get 556.
Grab the next digit (3) from the dividend, add it to 556, then carry on: 5563 / 980

Let's proceed to step 5:
5563 divided by 980 is 5 with a remainder of 663.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 4900 from 5563 leaves us with 663.
Grab the next digit (9) from the dividend, add it to 663, then carry on: 6639 / 980

Going ahead to step 6:
980 can be fit into 6639 6 times, resulting in a remainder of 759.
Use 6 as the next digit of our solution. 
Result so far: 256.0
Subtract 5880 from 6639 to get 759.
Grab the next digit (6) from the dividend, add it to 759, then carry on: 7596 / 980

On to step 7:
980 goes into 7596 7 times with a remainder of 736.
Write down 7 as next digit of the result. 
Result so far: 2567.0
Subtracting 6860 from 7596 leaves us with 736.
Take the next digit (2) from the dividend and append it to 736, then repeat: 7362 / 980

On to step 8:
The number 980 fits into 7362 7 times, leaving a remainder of 502.
Use 7 as the next digit of our solution. 
Result so far: 25677.0
Subtract 6860 from 7362 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 9:
The number 980 fits into 5020 5 times, leaving a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 25677.5
Subtracting 4900 from 5020 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 10:
980 goes into 1200 1 times with a remainder of 220.
The number 1 becomes the next digit in our result. 
Result so far: 25677.51
If we take 980 away from 1200, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 11:
When dividing 2200 by 980, we get 2 with a remainder of 240.
Use 2 as the next digit of our solution. 
Result so far: 25677.512
Deduct 1960 from 2200 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
The number 980 fits into 2400 2 times, leaving a remainder of 440.
The next digit of our result is 2. 
Result so far: 25677.5122
Deduct 1960 from 2400 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final result is 25677.5122 with a remainder of 0.0044.
