We divide 810641 by 50
The aim is to understand the frequency of 50 in 810641.

Advancing to step 1:
When dividing 8 by 50, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 50

On to step 2:
If we divide 81 by 50, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 50 from 81, we get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 50

Moving on to step 3:
When dividing 310 by 50, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 300 from 310, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 50

Step 4:
The number 50 fits into 106 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 162.0
Subtract 100 from 106 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 50

Step 5:
50 goes into 64 1 times with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1621.0
If we take 50 away from 64, we end up with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 50

Moving on to step 6:
The number 50 fits into 141 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 16212.0
If we subtract 100 from 141, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
410 divided by 50 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 16212.8
The remainder is 10 after subtracting 400 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
50 goes into 100 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 16212.82
Subtracting 100 from 100 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.

Step 9:
50 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 16212.82
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.

Step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16212.82
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.

After the division, we end up with 16212.82 and a remainder of 0.0.
