We divide 628640 by 45
Let's see how many times 45 fits into 628640.

Moving on to step 1:
6 divided by 45 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 45

On to step 2:
45 goes into 62 1 times with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 45 from 62 to get 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 45

Advancing to step 3:
The number 45 fits into 178 3 times, leaving a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 135 from 178 to get 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 45

Going ahead to step 4:
45 can be fit into 436 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 139.0
If we take 405 away from 436, we end up with 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 45

On to step 5:
314 divided by 45 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1396.0
If we subtract 270 from 314, we get 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 45

Let's proceed to step 6:
The number 45 fits into 440 9 times, leaving a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 13969.0
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
When dividing 350 by 45, we get 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 13969.7
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
45 goes into 350 7 times with a remainder of 35.
The number 7 becomes the next digit in our result. 
Result so far: 13969.77
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 13969.77, and the remainder is 0.035.
