We're dividing 686526 by 45 
We want to divide 686526 by 45.

Going ahead to step 1:
When dividing 6 by 45, we get 0 with 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.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 45

Let's proceed to step 2:
When dividing 68 by 45, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 68 to get 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 45

Moving on to step 3:
The number 45 fits into 236 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 225 from 236 and we're left with 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 45

Let's proceed to step 4:
45 goes into 115 2 times with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 152.0
Subtracting 90 from 115 leaves us with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 45

Step 5:
45 can be fit into 252 5 times, resulting in a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 1525.0
The remainder is 27 after subtracting 225 from 252.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 45

Step 6:
If we divide 276 by 45, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 15256.0
Subtracting 270 from 276 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
The number 45 fits into 60 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 15256.1
Deduct 45 from 60 and we're left 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 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 15256.13
Subtract 135 from 150 to get 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:
When dividing 150 by 45, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 15256.133
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 15256.133, and the remainder is 0.0015.
