15129 ÷ 6 
We want to divide 15129 by 6.

Step 1:
If we divide 1 by 6, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 6

Step 2:
15 divided by 6 is 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 12 from 15, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 6

On to step 3:
31 divided by 6 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 1 after subtracting 30 from 31.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 6

Advancing to step 4:
12 divided by 6 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 252.0
If we take 12 away from 12, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 6

Moving on to step 5:
6 can be fit into 9 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 2521.0
If we take 6 away from 9, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
30 divided by 6 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2521.5
Deduct 30 from 30 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2521.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 6, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2521.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 2521.5, and the remainder is 0.0.
