Let's divide 685887 by 45
We want to divide 685887 by 45.

Going ahead to step 1:
When dividing 6 by 45, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 45

Advancing to step 2:
68 divided by 45 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 23 after subtracting 45 from 68.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 45

Moving on to step 3:
45 can be fit into 235 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 10 after subtracting 225 from 235.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 45

Step 4:
45 goes into 108 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtract 90 from 108 to get 18.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 45

Going ahead to step 5:
45 goes into 188 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1524.0
If we subtract 180 from 188, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 45

Step 6:
87 divided by 45 is 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 15241.0
Subtracting 45 from 87 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
If we divide 420 by 45, we get 9 and a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 15241.9
The remainder is 15 after subtracting 405 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
150 divided by 45 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 15241.93
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
45 goes into 150 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 15241.933
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 15241.933 and a remainder of 0.0015.
