We look at the division of 687623 by 15 
We want to divide 687623 by 15.

On to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 15

Advancing to step 2:
When dividing 68 by 15, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 60 from 68 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 15

Advancing to step 3:
If we divide 87 by 15, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 75 away from 87, we end up with 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 15

Moving on to step 4:
126 divided by 15 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 458.0
The remainder is 6 after subtracting 120 from 126.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 15

Going ahead to step 5:
If we divide 62 by 15, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 4584.0
If we take 60 away from 62, we end up with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 15

Step 6:
When dividing 23 by 15, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 45841.0
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.

Moving on to 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: 45841.5
Deduct 75 from 80 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 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 45841.53
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.

Let's proceed to step 9:
15 goes into 50 3 times with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 45841.533
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.

The quotient of the division is 45841.533, and the remainder is 0.0005.
