644148 divided by 50 
We want to figure out the number of times 644148 can be divided by 50.

Let's proceed to step 1:
50 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
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 50

Let's proceed to step 2:
50 can be fit into 64 1 times, resulting in a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 50 from 64 leaves us with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 50

Advancing to step 3:
50 can be fit into 144 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 100 from 144 to get 44.
Fetch the next digit (1) from the dividend, attach it to 44 and continue: 441 / 50

Going ahead to step 4:
50 can be fit into 441 8 times, resulting in a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtract 400 from 441 to get 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 50

On to step 5:
50 goes into 414 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 1288.0
If we subtract 400 from 414, we get 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 50

Advancing to step 6:
50 goes into 148 2 times with a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 12882.0
If we take 100 away from 148, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
When dividing 480 by 50, we get 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 12882.9
Subtract 450 from 480 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 50 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 12882.96
If we subtract 300 from 300, 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.

Let's proceed to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12882.96
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.

Going ahead to step 10:
0 divided by 50 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12882.96
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.

Our division results in 12882.96 with a remaining 0.0.
