981089 divided by 50 
The aim is to understand the frequency of 50 in 981089.

On to step 1:
When dividing 9 by 50, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 50

Step 2:
If we divide 98 by 50, we get 1 and a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 50 from 98 to get 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 50

On to step 3:
The number 50 fits into 481 9 times, leaving a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 31 after subtracting 450 from 481.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 50

On to step 4:
310 divided by 50 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 196.0
The remainder is 10 after subtracting 300 from 310.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 50

Let's proceed to step 5:
50 can be fit into 108 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 1962.0
Deduct 100 from 108 and we're left with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 50

Step 6:
89 divided by 50 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 19621.0
Deduct 50 from 89 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
When dividing 390 by 50, we get 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 19621.7
Deduct 350 from 390 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
50 can be fit into 400 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 19621.78
Subtracting 400 from 400 leaves us 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 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19621.78
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.

On to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19621.78
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.

After the division, we end up with 19621.78 and a remainder of 0.0.
