687507 divided by 45 
We're looking to find how many times 45 goes into 687507.

Going ahead to step 1:
6 divided by 45 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 45

Going ahead to step 2:
68 divided by 45 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 68 and we're left with 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 45

Going ahead to step 3:
When dividing 237 by 45, we get 5 with a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 225 from 237 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 45

Advancing to step 4:
45 can be fit into 125 2 times, resulting in a remainder of 35.
The next digit of our result is 2. 
Result so far: 152.0
The remainder is 35 after subtracting 90 from 125.
Fetch the next digit (0) from the dividend, attach it to 35 and continue: 350 / 45

Let's proceed to step 5:
45 goes into 350 7 times with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 1527.0
Subtracting 315 from 350 leaves us with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 45

On to step 6:
45 can be fit into 357 7 times, resulting in a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 15277.0
Subtract 315 from 357 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
When dividing 420 by 45, we get 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 15277.9
If we take 405 away from 420, we end up with 15.
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:
45 goes into 150 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 15277.93
If we take 135 away from 150, we end up with 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 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 15277.933
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 15277.933 with a balance of 0.0015.
