We're dividing 667780 by 45 
We want to divide 667780 by 45.

Let's proceed 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
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 45

On to step 2:
If we divide 66 by 45, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 66 leaves us with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 45

Step 3:
45 can be fit into 217 4 times, resulting in a remainder of 37.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Deduct 180 from 217 and we're left with 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 45

Moving on to step 4:
45 can be fit into 377 8 times, resulting in a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we subtract 360 from 377, we get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 45

On to step 5:
45 goes into 178 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 1483.0
If we subtract 135 from 178, we get 43.
Bring next digit (0) of the dividend behind the 43 and repeat the process: 430 / 45

Moving on to step 6:
The number 45 fits into 430 9 times, leaving a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 14839.0
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 14839.5
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
When dividing 250 by 45, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 14839.55
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 14839.55 with a remainder of 0.025.
