We look at the division of 683685 by 45 
We want to divide 683685 by 45.

Going ahead to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 45

Moving on to step 2:
68 divided by 45 is 1 with 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.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 45

Advancing to step 3:
45 can be fit into 233 5 times, resulting in a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 8 after subtracting 225 from 233.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 45

Let's proceed to step 4:
45 goes into 86 1 times with a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 151.0
The remainder is 41 after subtracting 45 from 86.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 45

Advancing to step 5:
If we divide 418 by 45, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 1519.0
The remainder is 13 after subtracting 405 from 418.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 45

Going ahead to step 6:
135 divided by 45 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 15193.0
Subtract 135 from 135 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 45, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15193.0
Subtract 0 from 0 to get 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:
0 divided by 45 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15193.0
If we take 0 away from 0, we end up 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.

Our division results in 15193.0 with a remaining 0.0.
