We look at the division of 25100818 by 561 
We want to divide 25100818 by 561.

Moving on to step 1:
2 divided by 561 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 561

On to step 2:
561 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 561

Advancing to step 3:
When dividing 251 by 561, we get 0 with a remainder of 251.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 251, we get 251.
Take the next digit (0) from the dividend and append it to 251, then repeat: 2510 / 561

Going ahead to step 4:
2510 divided by 561 is 4 with a remainder of 266.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 266 after subtracting 2244 from 2510.
Fetch the next digit (0) from the dividend, attach it to 266 and continue: 2660 / 561

Step 5:
561 can be fit into 2660 4 times, resulting in a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
The remainder is 416 after subtracting 2244 from 2660.
Take the next digit (8) from the dividend and append it to 416, then repeat: 4168 / 561

Moving on to step 6:
4168 divided by 561 is 7 with a remainder of 241.
Write down 7 as next digit of the result. 
Result so far: 447.0
Subtracting 3927 from 4168 leaves us with 241.
Fetch the next digit (1) from the dividend, attach it to 241 and continue: 2411 / 561

Moving on to step 7:
561 goes into 2411 4 times with a remainder of 167.
Use 4 as the next digit of our solution. 
Result so far: 4474.0
If we subtract 2244 from 2411, we get 167.
Bring next digit (8) of the dividend behind the 167 and repeat the process: 1678 / 561

Moving on to step 8:
When dividing 1678 by 561, we get 2 with a remainder of 556.
Put 2 as the next digit of the answer. 
Result so far: 44742.0
If we take 1122 away from 1678, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 9:
5560 divided by 561 is 9 with a remainder of 511.
Use 9 as the next digit of our solution. 
Result so far: 44742.9
Subtracting 5049 from 5560 leaves us with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Going ahead to step 10:
If we divide 5110 by 561, we get 9 and a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 44742.99
Subtract 5049 from 5110 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 44742.99 and a remainder of 0.061.
