628464 divided by 45 
We're looking to find how many times 45 goes into 628464.

Let's proceed to step 1:
6 divided by 45 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 45

On to step 2:
45 goes into 62 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 45 from 62 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 45

Moving on to step 3:
45 can be fit into 178 3 times, resulting in a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 135 from 178 to get 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 45

Going ahead to step 4:
When dividing 434 by 45, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 405 from 434, we get 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 45

Let's proceed to step 5:
45 goes into 296 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 1396.0
If we take 270 away from 296, we end up with 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 45

Let's proceed to step 6:
If we divide 264 by 45, we get 5 and a remainder of 39.
The next digit of our result is 5. 
Result so far: 13965.0
The remainder is 39 after subtracting 225 from 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
If we divide 390 by 45, we get 8 and a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 13965.8
Subtract 360 from 390 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
45 goes into 300 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 13965.86
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 45 is 6 with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 13965.866
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 13965.866, with a leftover of 0.003.
