We look at the division of 15262550 by 3 
We want to divide 15262550 by 3.

Step 1:
3 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Advancing to step 2:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 15 away from 15, we end up with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 3

Advancing to step 3:
3 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Step 4:
3 goes into 26 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 508.0
If we take 24 away from 26, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 3

Moving on to step 5:
3 goes into 22 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 5087.0
If we subtract 21 from 22, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Step 6:
3 can be fit into 15 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 50875.0
Subtract 15 from 15 to get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 3

On to step 7:
5 divided by 3 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 508751.0
If we take 3 away from 5, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Moving on to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 5087516.0
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 5087516.6
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 5087516.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 5087516.66, and the remainder is 0.002.
