We divide 801568 by 50
The aim is to understand the frequency of 50 in 801568.

Advancing to step 1:
If we divide 8 by 50, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 50

On to step 2:
80 divided by 50 is 1 with a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 50 from 80, we get 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 50

Step 3:
50 can be fit into 301 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 1 after subtracting 300 from 301.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 50

Going ahead to step 4:
15 divided by 50 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 50

On to step 5:
The number 50 fits into 156 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 1603.0
The remainder is 6 after subtracting 150 from 156.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 50

Going ahead to step 6:
68 divided by 50 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 16031.0
If we take 50 away from 68, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
The number 50 fits into 180 3 times, leaving a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 16031.3
Subtracting 150 from 180 leaves us 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.

Advancing to step 8:
If we divide 300 by 50, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 16031.36
If we take 300 away from 300, 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.

Moving on to step 9:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16031.36
Subtracting 0 from 0 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 10:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16031.36
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.

Our division results in 16031.36 with a remaining 0.0.
