We're dividing 30171778 by 635 
We want to figure out the number of times 30171778 can be divided by 635.

Going ahead to step 1:
When dividing 3 by 635, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 635

Going ahead to step 2:
635 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 635

Moving on to step 3:
635 goes into 301 0 times with a remainder of 301.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 301 leaves us with 301.
Bring next digit (7) of the dividend behind the 301 and repeat the process: 3017 / 635

Advancing to step 4:
The number 635 fits into 3017 4 times, leaving a remainder of 477.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 2540 away from 3017, we end up with 477.
Bring next digit (1) of the dividend behind the 477 and repeat the process: 4771 / 635

On to step 5:
If we divide 4771 by 635, we get 7 and a remainder of 326.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we take 4445 away from 4771, we end up with 326.
Fetch the next digit (7) from the dividend, attach it to 326 and continue: 3267 / 635

Step 6:
The number 635 fits into 3267 5 times, leaving a remainder of 92.
Write down 5 as next digit of the result. 
Result so far: 475.0
Subtract 3175 from 3267 to get 92.
Fetch the next digit (7) from the dividend, attach it to 92 and continue: 927 / 635

Going ahead to step 7:
635 can be fit into 927 1 times, resulting in a remainder of 292.
Use 1 as the next digit of our solution. 
Result so far: 4751.0
The remainder is 292 after subtracting 635 from 927.
Append the next digit (8) from the dividend to 292 and continue with: 2928 / 635

Going ahead to step 8:
635 can be fit into 2928 4 times, resulting in a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 47514.0
If we take 2540 away from 2928, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 9:
The number 635 fits into 3880 6 times, leaving a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 47514.6
If we take 3810 away from 3880, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 10:
The number 635 fits into 700 1 times, leaving a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 47514.61
Subtracting 635 from 700 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
650 divided by 635 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 47514.611
Subtract 635 from 650 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 47514.611 with a remainder of 0.0015.
