We look at the division of 630290 by 40 
We want to divide 630290 by 40.

Going ahead to step 1:
40 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 40

Let's proceed to step 2:
40 goes into 63 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 40 from 63 leaves us with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 40

Advancing to step 3:
When dividing 230 by 40, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 200 from 230 to get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 40

On to step 4:
The number 40 fits into 302 7 times, leaving a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 157.0
If we take 280 away from 302, we end up with 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 40

Advancing to step 5:
If we divide 229 by 40, we get 5 and a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 1575.0
If we subtract 200 from 229, we get 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 40

Let's proceed to step 6:
290 divided by 40 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 15757.0
Subtract 280 from 290 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
100 divided by 40 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 15757.2
Subtract 80 from 100 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15757.25
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15757.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15757.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 15757.25, and the remainder is 0.0.
