Let's divide 12894636 by 15
We want to divide 12894636 by 15.

Let's proceed to step 1:
If we divide 1 by 15, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 15

On to step 2:
15 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 15

Step 3:
When dividing 128 by 15, we get 8 with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 8 after subtracting 120 from 128.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 15

Step 4:
15 goes into 89 5 times with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we subtract 75 from 89, we get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 15

Advancing to step 5:
When dividing 144 by 15, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 859.0
Deduct 135 from 144 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 15

Going ahead to step 6:
If we divide 96 by 15, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 8596.0
Subtract 90 from 96 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 15

Going ahead to step 7:
The number 15 fits into 63 4 times, leaving a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 85964.0
If we take 60 away from 63, we end up with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 15

On to step 8:
36 divided by 15 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 859642.0
If we subtract 30 from 36, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
15 can be fit into 60 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 859642.4
Deduct 60 from 60 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 10:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 859642.4
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.

On to step 11:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 859642.4
If we subtract 0 from 0, we 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.

Our division results in 859642.4 with a remaining 0.0.
