We're dividing 687690 by 45 
Our goal is to divide 687690 by 45.

Advancing to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 45

Going ahead to step 2:
The number 45 fits into 68 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 68, we get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 45

Advancing to step 3:
When dividing 237 by 45, we get 5 with a remainder of 12.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 225 from 237 to get 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 45

Step 4:
When dividing 126 by 45, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtract 90 from 126 to get 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 45

Advancing to step 5:
369 divided by 45 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 1528.0
Subtract 360 from 369 to get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 45

Step 6:
If we divide 90 by 45, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 15282.0
The remainder is 0 after subtracting 90 from 90.
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 7:
If we divide 0 by 45, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15282.0
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.

Advancing to step 8:
45 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 15282.0
If we subtract 0 from 0, we 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.

The final outcome is 15282.0, with a leftover of 0.0.
