25003330 ÷ 307 
We want to figure out the number of times 25003330 can be divided by 307.

On to step 1:
The number 307 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 307

Going ahead to step 2:
The number 307 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 307

Step 3:
250 divided by 307 is 0 with a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 250 leaves us with 250.
Include the next digit (0) from the dividend after 250, then repeat: 2500 / 307

Going ahead to step 4:
307 goes into 2500 8 times with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 2456 from 2500 leaves us with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 307

On to step 5:
The number 307 fits into 443 1 times, leaving a remainder of 136.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
The remainder is 136 after subtracting 307 from 443.
Append the next digit (3) from the dividend to 136 and continue with: 1363 / 307

Let's proceed to step 6:
When dividing 1363 by 307, we get 4 with a remainder of 135.
The next digit of our result is 4. 
Result so far: 814.0
Subtracting 1228 from 1363 leaves us with 135.
Include the next digit (3) from the dividend after 135, then repeat: 1353 / 307

Moving on to step 7:
The number 307 fits into 1353 4 times, leaving a remainder of 125.
Record the quotient 4 as the next digit in the result. 
Result so far: 8144.0
Subtracting 1228 from 1353 leaves us with 125.
Append the next digit (0) from the dividend to 125 and continue with: 1250 / 307

Advancing to step 8:
The number 307 fits into 1250 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 81444.0
The remainder is 22 after subtracting 1228 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
The number 307 fits into 220 0 times, leaving a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 81444.0
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
307 can be fit into 2200 7 times, resulting in a remainder of 51.
The next digit of our result is 7. 
Result so far: 81444.07
Deduct 2149 from 2200 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
510 divided by 307 is 1 with a remainder of 203.
Put 1 as the next digit of the answer. 
Result so far: 81444.071
Subtracting 307 from 510 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

On to step 12:
307 can be fit into 2030 6 times, resulting in a remainder of 188.
The number 6 becomes the next digit in our result. 
Result so far: 81444.0716
Subtracting 1842 from 2030 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 13:
307 goes into 1880 6 times with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 81444.07166
If we take 1842 away from 1880, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 81444.07166 and a remainder of 3.8e-05.
