990657 ÷ 50 
The aim is to understand the frequency of 50 in 990657.

Let's proceed to step 1:
9 divided by 50 is 0 with 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 (9) of the dividend behind the 9 and repeat the process: 99 / 50

Step 2:
99 divided by 50 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 50 from 99 leaves us with 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 50

Step 3:
The number 50 fits into 490 9 times, leaving a remainder of 40.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 40 after subtracting 450 from 490.
Bring next digit (6) of the dividend behind the 40 and repeat the process: 406 / 50

Moving on to step 4:
The number 50 fits into 406 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 198.0
If we take 400 away from 406, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 50

Let's proceed to step 5:
When dividing 65 by 50, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1981.0
Subtract 50 from 65 to get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 50

Advancing to step 6:
The number 50 fits into 157 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 19813.0
If we subtract 150 from 157, we get 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:
70 divided by 50 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 19813.1
Subtract 50 from 70 to get 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:
When dividing 200 by 50, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 19813.14
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.

On to step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19813.14
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.

Moving on to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19813.14
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.

After the division, we end up with 19813.14 and a remainder of 0.0.
