Let's divide 888173 by 15
We want to figure out the number of times 888173 can be divided by 15.

Step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 15

Let's proceed to step 2:
The number 15 fits into 88 5 times, leaving a remainder of 13.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 75 from 88 to get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 15

Moving on to step 3:
When dividing 138 by 15, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Deduct 135 from 138 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 15

Going ahead to step 4:
When dividing 31 by 15, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 592.0
If we take 30 away from 31, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 15

Moving on to step 5:
When dividing 17 by 15, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 5921.0
Deduct 15 from 17 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 15

On to step 6:
When dividing 23 by 15, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 59211.0
If we take 15 away from 23, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 15, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 59211.5
The remainder is 5 after subtracting 75 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 59211.53
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.

Advancing to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 59211.533
If we take 45 away from 50, we end up 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.

The final result is 59211.533 with a remainder of 0.0005.
