685161 ÷ 45 
We're looking to find how many times 45 goes into 685161.

On to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 45

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
Deduct 45 from 68 and we're left with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 45

Step 3:
45 goes into 235 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 10 after subtracting 225 from 235.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 45

Step 4:
If we divide 101 by 45, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Deduct 90 from 101 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 45

Step 5:
45 goes into 116 2 times with a remainder of 26.
The next digit of our result is 2. 
Result so far: 1522.0
Subtract 90 from 116 to get 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 45

Moving on to step 6:
45 can be fit into 261 5 times, resulting in a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 15225.0
If we subtract 225 from 261, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
45 goes into 360 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 15225.8
Subtracting 360 from 360 leaves us 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.

Moving on to step 8:
45 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15225.8
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.

Let's proceed to step 9:
45 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15225.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 15225.8 with a balance of 0.0.
