We look at the division of 345446 by 50 
The aim is to understand the frequency of 50 in 345446.

Step 1:
3 divided by 50 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 50

Step 2:
If we divide 34 by 50, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 50

Advancing to step 3:
50 goes into 345 6 times with a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 300 from 345 leaves us with 45.
Fetch the next digit (4) from the dividend, attach it to 45 and continue: 454 / 50

Moving on to step 4:
50 can be fit into 454 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtracting 450 from 454 leaves us with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 50

Advancing to step 5:
50 goes into 44 0 times with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 690.0
The remainder is 44 after subtracting 0 from 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 50

Moving on to step 6:
446 divided by 50 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 6908.0
Subtract 400 from 446 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
The number 50 fits into 460 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 6908.9
The remainder is 10 after subtracting 450 from 460.
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:
50 goes into 100 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 6908.92
The remainder is 0 after subtracting 100 from 100.
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 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6908.92
If we take 0 away from 0, we end up 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.

Advancing to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6908.92
Subtract 0 from 0 to 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 6908.92 with a remainder of 0.0.
