We divide 686918 by 45
Our goal is to divide 686918 by 45.

Moving on to step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 45

On to step 2:
The number 45 fits into 68 1 times, leaving a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 45 from 68 leaves us with 23.
Include the next digit (6) from the dividend after 23, then repeat: 236 / 45

Advancing to step 3:
236 divided by 45 is 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 225 from 236 to get 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 45

Advancing to step 4:
119 divided by 45 is 2 with a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 152.0
If we take 90 away from 119, we end up with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 45

Step 5:
When dividing 291 by 45, we get 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 1526.0
If we subtract 270 from 291, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 45

Let's proceed to step 6:
45 can be fit into 218 4 times, resulting in a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 15264.0
Deduct 180 from 218 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
The number 45 fits into 380 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 15264.8
Subtract 360 from 380 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
45 goes into 200 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 15264.84
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
45 can be fit into 200 4 times, resulting in a remainder of 20.
The next digit of our result is 4. 
Result so far: 15264.844
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 15264.844 with a remainder of 0.002.
