We're dividing 685660 by 45 
We want to figure out the number of times 685660 can be divided by 45.

Step 1:
When dividing 6 by 45, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 45

Moving on to step 2:
If we divide 68 by 45, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 45 from 68, we get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 45

Step 3:
If we divide 235 by 45, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 225 from 235 and we're left with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 45

On to step 4:
The number 45 fits into 106 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 152.0
Subtract 90 from 106 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 45

Moving on to step 5:
45 can be fit into 166 3 times, resulting in a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 1523.0
Subtract 135 from 166 to get 31.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 45

Let's proceed to step 6:
When dividing 310 by 45, we get 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 15236.0
Deduct 270 from 310 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
400 divided by 45 is 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 15236.8
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 15236.88
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 15236.88 with a balance of 0.04.
