We're dividing 17801294 by 15 
Let's see how many times 15 fits into 17801294.

On to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 15

Advancing to step 2:
15 can be fit into 17 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 15 away from 17, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 15

On to step 3:
The number 15 fits into 28 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 15 away from 28, we end up with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 15

Going ahead to step 4:
If we divide 130 by 15, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 118.0
If we subtract 120 from 130, we get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 15

Advancing to step 5:
15 goes into 101 6 times with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 1186.0
Subtract 90 from 101 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 15

Let's proceed to step 6:
15 can be fit into 112 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 11867.0
Deduct 105 from 112 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 15

On to step 7:
When dividing 79 by 15, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 118675.0
If we take 75 away from 79, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 15

On to step 8:
If we divide 44 by 15, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1186752.0
The remainder is 14 after subtracting 30 from 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
15 can be fit into 140 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 1186752.9
The remainder is 5 after subtracting 135 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 1186752.93
Deduct 45 from 50 and we're left 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.

Step 11:
50 divided by 15 is 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 1186752.933
Subtracting 45 from 50 leaves us 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.

Our division results in 1186752.933 with a remaining 0.0005.
