Let's divide 90898803 by 50
The aim is to understand the frequency of 50 in 90898803.

Step 1:
If we divide 9 by 50, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 50

Advancing to step 2:
If we divide 90 by 50, we get 1 and a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 50 from 90, we get 40.
Append the next digit (8) from the dividend to 40 and continue with: 408 / 50

On to step 3:
50 can be fit into 408 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 400 away from 408, we end up with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 50

Going ahead to step 4:
89 divided by 50 is 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 181.0
Subtract 50 from 89 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 50

Moving on to step 5:
50 goes into 398 7 times with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 1817.0
If we take 350 away from 398, we end up with 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 50

Advancing to step 6:
If we divide 488 by 50, we get 9 and a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 18179.0
Subtract 450 from 488 to get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 50

Moving on to step 7:
50 can be fit into 380 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 181797.0
Subtracting 350 from 380 leaves us with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 50

On to step 8:
If we divide 303 by 50, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 1817976.0
Subtracting 300 from 303 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
If we divide 30 by 50, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1817976.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
300 divided by 50 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 1817976.06
The remainder is 0 after subtracting 300 from 300.
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 11:
0 divided by 50 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1817976.06
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.

On to step 12:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1817976.06
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.

The final outcome is 1817976.06, with a leftover of 0.0.
