We look at the division of 63430420 by 240 
We want to figure out the number of times 63430420 can be divided by 240.

On to step 1:
6 divided by 240 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 240

On to step 2:
63 divided by 240 is 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (4) from the dividend to 63 and continue with: 634 / 240

Going ahead to step 3:
The number 240 fits into 634 2 times, leaving a remainder of 154.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 480 from 634, we get 154.
Grab the next digit (3) from the dividend, add it to 154, then carry on: 1543 / 240

Let's proceed to step 4:
240 can be fit into 1543 6 times, resulting in a remainder of 103.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtract 1440 from 1543 to get 103.
Bring next digit (0) of the dividend behind the 103 and repeat the process: 1030 / 240

Moving on to step 5:
240 goes into 1030 4 times with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 264.0
Subtract 960 from 1030 to get 70.
Take the next digit (4) from the dividend and append it to 70, then repeat: 704 / 240

Advancing to step 6:
The number 240 fits into 704 2 times, leaving a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 2642.0
The remainder is 224 after subtracting 480 from 704.
Take the next digit (2) from the dividend and append it to 224, then repeat: 2242 / 240

Let's proceed to step 7:
240 goes into 2242 9 times with a remainder of 82.
The next digit of our result is 9. 
Result so far: 26429.0
Subtracting 2160 from 2242 leaves us with 82.
Take the next digit (0) from the dividend and append it to 82, then repeat: 820 / 240

Let's proceed to step 8:
240 can be fit into 820 3 times, resulting in a remainder of 100.
Put 3 as the next digit of the answer. 
Result so far: 264293.0
If we take 720 away from 820, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 9:
1000 divided by 240 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 264293.4
Deduct 960 from 1000 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 10:
The number 240 fits into 400 1 times, leaving a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 264293.41
Subtracting 240 from 400 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 11:
240 goes into 1600 6 times with a remainder of 160.
The number 6 becomes the next digit in our result. 
Result so far: 264293.416
Subtract 1440 from 1600 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 12:
The number 240 fits into 1600 6 times, leaving a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 264293.4166
Subtracting 1440 from 1600 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 264293.4166, and the remainder is 0.0016.
