689189 divided by 15 
We want to figure out the number of times 689189 can be divided by 15.

On to step 1:
6 divided by 15 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in 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

Let's proceed to step 2:
If we divide 68 by 15, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 60 from 68 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 15

On to step 3:
If we divide 89 by 15, we get 5 and a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtract 75 from 89 to get 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 15

Going ahead to step 4:
15 can be fit into 141 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 459.0
Subtract 135 from 141 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 15

Going ahead to step 5:
15 can be fit into 68 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4594.0
If we take 60 away from 68, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 15

Moving on to step 6:
When dividing 89 by 15, we get 5 with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 45945.0
Subtract 75 from 89 to get 14.
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 7:
140 divided by 15 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 45945.9
Subtract 135 from 140 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
If we divide 50 by 15, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 45945.93
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.

Moving on to step 9:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 45945.933
If we subtract 45 from 50, we get 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 45945.933 with a remaining 0.0005.
