672791 ÷ 45 
We're looking to find how many times 45 goes into 672791.

Going ahead to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 45

Step 2:
If we divide 67 by 45, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 45 from 67, we get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 45

Advancing to step 3:
222 divided by 45 is 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we take 180 away from 222, we end up with 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 45

Let's proceed to step 4:
45 goes into 427 9 times with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtract 405 from 427 to get 22.
Take the next digit (9) from the dividend and append it to 22, then repeat: 229 / 45

Going ahead to step 5:
The number 45 fits into 229 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 1495.0
If we subtract 225 from 229, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 45

Going ahead to step 6:
The number 45 fits into 41 0 times, leaving a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 14950.0
The remainder is 41 after subtracting 0 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
45 can be fit into 410 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 14950.9
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
50 divided by 45 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 14950.91
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
When dividing 50 by 45, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 14950.911
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 14950.911 with a remainder of 0.0005.
