689616 ÷ 45 
We're looking to find how many times 45 goes into 689616.

Moving on to step 1:
If we divide 6 by 45, we get 0 and 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.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 45

Step 2:
68 divided by 45 is 1 with a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 68, we get 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 45

Going ahead to step 3:
239 divided by 45 is 5 with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 225 from 239 leaves us with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 45

Let's proceed to step 4:
45 goes into 146 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 153.0
Subtract 135 from 146 to get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 45

Let's proceed to step 5:
If we divide 111 by 45, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 1532.0
Subtract 90 from 111 to get 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 45

Step 6:
45 goes into 216 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 15324.0
Subtracting 180 from 216 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
If we divide 360 by 45, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 15324.8
If we subtract 360 from 360, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15324.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 45 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15324.8
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 15324.8 with a remainder of 0.0.
