We divide 25080055 by 310
We want to figure out the number of times 25080055 can be divided by 310.

Going ahead to step 1:
When dividing 2 by 310, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 310

Advancing to step 2:
25 divided by 310 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 310

On to step 3:
310 can be fit into 250 0 times, resulting in a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 250 after subtracting 0 from 250.
Take the next digit (8) from the dividend and append it to 250, then repeat: 2508 / 310

On to step 4:
2508 divided by 310 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 2480 from 2508 and we're left with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 310

Going ahead to step 5:
280 divided by 310 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 80.0
If we subtract 0 from 280, we get 280.
Fetch the next digit (0) from the dividend, attach it to 280 and continue: 2800 / 310

Step 6:
310 goes into 2800 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 809.0
Subtracting 2790 from 2800 leaves us with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 310

Moving on to step 7:
310 goes into 105 0 times with a remainder of 105.
Put 0 as the next digit of the answer. 
Result so far: 8090.0
If we take 0 away from 105, we end up with 105.
Take the next digit (5) from the dividend and append it to 105, then repeat: 1055 / 310

On to step 8:
If we divide 1055 by 310, we get 3 and a remainder of 125.
Use 3 as the next digit of our solution. 
Result so far: 80903.0
Subtract 930 from 1055 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 9:
If we divide 1250 by 310, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 80903.4
If we take 1240 away from 1250, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
310 can be fit into 100 0 times, resulting in a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 80903.4
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
The number 310 fits into 1000 3 times, leaving a remainder of 70.
The next digit of our result is 3. 
Result so far: 80903.403
The remainder is 70 after subtracting 930 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
If we divide 700 by 310, we get 2 and a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 80903.4032
If we subtract 620 from 700, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
If we divide 800 by 310, we get 2 and a remainder of 180.
Use 2 as the next digit of our solution. 
Result so far: 80903.40322
If we subtract 620 from 800, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 80903.40322 with a remaining 0.00018.
