We look at the division of 644252 by 49 
We want to figure out the number of times 644252 can be divided by 49.

Let's proceed to step 1:
If we divide 6 by 49, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 49

Moving on to step 2:
49 goes into 64 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 15 after subtracting 49 from 64.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 49

Advancing to step 3:
154 divided by 49 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 13.0
If we take 147 away from 154, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 49

Step 4:
49 can be fit into 72 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 131.0
Subtracting 49 from 72 leaves us with 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 49

Advancing to step 5:
235 divided by 49 is 4 with a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 1314.0
Deduct 196 from 235 and we're left with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 49

On to step 6:
49 goes into 392 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 13148.0
The remainder is 0 after subtracting 392 from 392.
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 7:
0 divided by 49 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13148.0
Subtracting 0 from 0 leaves us 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.

On to step 8:
If we divide 0 by 49, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13148.0
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.

The final result is 13148.0 with a remainder of 0.0.
