We divide 663781 by 49
We want to figure out the number of times 663781 can be divided by 49.

On to step 1:
49 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 49

Step 2:
If we divide 66 by 49, we get 1 and a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 49 from 66 leaves us with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 49

Step 3:
If we divide 173 by 49, we get 3 and a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtract 147 from 173 to get 26.
Take the next digit (7) from the dividend and append it to 26, then repeat: 267 / 49

Going ahead to step 4:
When dividing 267 by 49, we get 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 135.0
Subtract 245 from 267 to get 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 49

Moving on to step 5:
228 divided by 49 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 1354.0
Subtracting 196 from 228 leaves us with 32.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 49

Going ahead to step 6:
49 goes into 321 6 times with a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 13546.0
Subtracting 294 from 321 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
49 can be fit into 270 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 13546.5
Subtract 245 from 270 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
The number 49 fits into 250 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 13546.55
Deduct 245 from 250 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 13546.55 with a remaining 0.005.
