15275815 ÷ 606 
We want to figure out the number of times 15275815 can be divided by 606.

Advancing to step 1:
If we divide 1 by 606, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 606

Moving on to step 2:
If we divide 15 by 606, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 606

Let's proceed to step 3:
152 divided by 606 is 0 with a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 152, we get 152.
Append the next digit (7) from the dividend to 152 and continue with: 1527 / 606

Going ahead to step 4:
The number 606 fits into 1527 2 times, leaving a remainder of 315.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1212 from 1527 leaves us with 315.
Include the next digit (5) from the dividend after 315, then repeat: 3155 / 606

Moving on to step 5:
The number 606 fits into 3155 5 times, leaving a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 3030 from 3155 leaves us with 125.
Fetch the next digit (8) from the dividend, attach it to 125 and continue: 1258 / 606

Step 6:
606 goes into 1258 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
The remainder is 46 after subtracting 1212 from 1258.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 606

Advancing to step 7:
The number 606 fits into 461 0 times, leaving a remainder of 461.
The number 0 becomes the next digit in our result. 
Result so far: 2520.0
Deduct 0 from 461 and we're left with 461.
Grab the next digit (5) from the dividend, add it to 461, then carry on: 4615 / 606

Going ahead to step 8:
4615 divided by 606 is 7 with a remainder of 373.
The number 7 becomes the next digit in our result. 
Result so far: 25207.0
Subtract 4242 from 4615 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 9:
3730 divided by 606 is 6 with a remainder of 94.
Put 6 as the next digit of the answer. 
Result so far: 25207.6
Subtracting 3636 from 3730 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
When dividing 940 by 606, we get 1 with a remainder of 334.
Use 1 as the next digit of our solution. 
Result so far: 25207.61
Subtract 606 from 940 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Going ahead to step 11:
When dividing 3340 by 606, we get 5 with a remainder of 310.
Record the quotient 5 as the next digit in the result. 
Result so far: 25207.615
Subtract 3030 from 3340 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 12:
606 can be fit into 3100 5 times, resulting in a remainder of 70.
The next digit of our result is 5. 
Result so far: 25207.6155
If we take 3030 away from 3100, 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.

The quotient of the division is 25207.6155, and the remainder is 0.0007.
