We divide 500902 by 50
The aim is to understand the frequency of 50 in 500902.

Advancing to step 1:
5 divided by 50 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 50

On to step 2:
The number 50 fits into 50 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 50 from 50 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 50

Advancing to step 3:
0 divided by 50 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 50

Advancing to step 4:
9 divided by 50 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 50

Step 5:
If we divide 90 by 50, we get 1 and a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1001.0
Subtract 50 from 90 to get 40.
Include the next digit (2) from the dividend after 40, then repeat: 402 / 50

Step 6:
If we divide 402 by 50, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 10018.0
If we subtract 400 from 402, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
50 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10018.0
Subtracting 0 from 20 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:
50 can be fit into 200 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 10018.04
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 50 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10018.04
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.

On to step 10:
When dividing 0 by 50, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10018.04
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.

Our division results in 10018.04 with a remaining 0.0.
