646001 divided by 50 
The aim is to understand the frequency of 50 in 646001.

On to step 1:
50 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 50

Advancing to step 2:
50 can be fit into 64 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 50 from 64, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 50

On to step 3:
If we divide 146 by 50, we get 2 and a remainder of 46.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 46 after subtracting 100 from 146.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 50

Advancing to step 4:
50 can be fit into 460 9 times, resulting in a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we take 450 away from 460, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 50

Moving on to step 5:
When dividing 100 by 50, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 1292.0
Subtracting 100 from 100 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 50

Step 6:
50 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 12920.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
50 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12920.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 50 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12920.02
If we subtract 100 from 100, 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.

On to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12920.02
Deduct 0 from 0 and we're left 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.

Let's proceed to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12920.02
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 12920.02 with a remaining 0.0.
