693679 ÷ 45 
Our goal is to divide 693679 by 45.

Let's proceed to 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
If we subtract 0 from 6, we get 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 45

Step 2:
The number 45 fits into 69 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 69, we get 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 45

Let's proceed to step 3:
243 divided by 45 is 5 with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 225 from 243 leaves us with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 45

Moving on to step 4:
186 divided by 45 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtract 180 from 186 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 45

On to step 5:
45 goes into 67 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1541.0
Subtracting 45 from 67 leaves us with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 45

Moving on to step 6:
45 can be fit into 229 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 15415.0
Deduct 225 from 229 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 45 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 15415.0
If we subtract 0 from 40, we 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:
The number 45 fits into 400 8 times, leaving a remainder of 40.
The next digit of our result is 8. 
Result so far: 15415.08
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.

Moving on to step 9:
If we divide 400 by 45, we get 8 and a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 15415.088
Deduct 360 from 400 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.

The final result is 15415.088 with a remainder of 0.004.
