We divide 645807 by 50
We're looking to find how many times 50 goes into 645807.

Let's proceed to step 1:
The number 50 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 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 goes into 64 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 50 from 64, we get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 50

Moving on to step 3:
If we divide 145 by 50, we get 2 and a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 100 from 145, we get 45.
Grab the next digit (8) from the dividend, add it to 45, then carry on: 458 / 50

Going ahead to step 4:
458 divided by 50 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Subtracting 450 from 458 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 50

Advancing to step 5:
50 goes into 80 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1291.0
If we take 50 away from 80, we end up with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 50

Let's proceed to step 6:
The number 50 fits into 307 6 times, leaving a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 12916.0
Subtracting 300 from 307 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 50 fits into 70 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 12916.1
Subtracting 50 from 70 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 50 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 12916.14
If we subtract 200 from 200, 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:
0 divided by 50 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12916.14
The remainder is 0 after subtracting 0 from 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:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12916.14
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.

Our division results in 12916.14 with a remaining 0.0.
