Let's divide 801691 by 50
The aim is to understand the frequency of 50 in 801691.

Step 1:
If we divide 8 by 50, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 50

Step 2:
50 can be fit into 80 1 times, resulting in a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 30 after subtracting 50 from 80.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 50

Moving on to step 3:
50 can be fit into 301 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 300 from 301 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 50

Let's proceed to step 4:
50 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 160.0
Subtract 0 from 16 to get 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 50

Going ahead to step 5:
169 divided by 50 is 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 1603.0
If we take 150 away from 169, we end up with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 50

Going ahead to step 6:
50 can be fit into 191 3 times, resulting in a remainder of 41.
The next digit of our result is 3. 
Result so far: 16033.0
Deduct 150 from 191 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 7:
50 can be fit into 410 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 16033.8
Subtracting 400 from 410 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
50 can be fit into 100 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 16033.82
If we take 100 away from 100, 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.

Going ahead to step 9:
50 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 16033.82
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.

Let's proceed to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 16033.82
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.

The quotient of the division is 16033.82, and the remainder is 0.0.
