We look at the division of 630319 by 45 
We want to figure out the number of times 630319 can be divided by 45.

Advancing to step 1:
If we divide 6 by 45, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 45

Going ahead to step 2:
45 goes into 63 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 45 from 63 and we're left with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 45

Let's proceed to step 3:
If we divide 180 by 45, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 180 from 180 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 45

Step 4:
45 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 140.0
If we subtract 0 from 3, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 45

On to step 5:
45 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 1400.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 45

Going ahead to step 6:
45 can be fit into 319 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 14007.0
Subtract 315 from 319 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
45 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 14007.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
400 divided by 45 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 14007.08
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
The number 45 fits into 400 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 14007.088
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 14007.088 with a remaining 0.004.
