Let's divide 685156 by 45
We want to divide 685156 by 45.

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

Moving on to step 2:
If we divide 68 by 45, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 68 and we're left with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 45

Step 3:
If we divide 235 by 45, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
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

Moving on to step 4:
If we divide 101 by 45, we get 2 and a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 152.0
The remainder is 11 after subtracting 90 from 101.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 45

Step 5:
If we divide 115 by 45, we get 2 and a remainder of 25.
The next digit of our result is 2. 
Result so far: 1522.0
The remainder is 25 after subtracting 90 from 115.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 45

Step 6:
45 goes into 256 5 times with a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 15225.0
If we subtract 225 from 256, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 45, we get 6 with a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 15225.6
Subtract 270 from 310 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.

Moving on to step 8:
400 divided by 45 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 15225.68
If we take 360 away from 400, we end up 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.

Let's proceed to step 9:
If we divide 400 by 45, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 15225.688
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.

The final result is 15225.688 with a remainder of 0.004.
