49209149 divided by 15 
We're looking to find how many times 15 goes into 49209149.

On to step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 15

Let's proceed to step 2:
15 can be fit into 49 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 45 from 49, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 15

On to step 3:
42 divided by 15 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 30 from 42 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 15

Going ahead to step 4:
The number 15 fits into 120 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 328.0
Deduct 120 from 120 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 15

Step 5:
15 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 3280.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 15

Step 6:
15 goes into 91 6 times with a remainder of 1.
The next digit of our result is 6. 
Result so far: 32806.0
Subtracting 90 from 91 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 15

Step 7:
14 divided by 15 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 328060.0
Subtract 0 from 14 to get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 15

Step 8:
149 divided by 15 is 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 3280609.0
The remainder is 14 after subtracting 135 from 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
When dividing 140 by 15, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 3280609.9
Subtract 135 from 140 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 3280609.93
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
If we divide 50 by 15, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3280609.933
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 3280609.933, and the remainder is 0.0005.
