42474950 divided by 811 
The aim is to understand the frequency of 811 in 42474950.

On to step 1:
811 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 811

Let's proceed to step 2:
When dividing 42 by 811, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 811

Let's proceed to step 3:
The number 811 fits into 424 0 times, leaving a remainder of 424.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 424 leaves us with 424.
Append the next digit (7) from the dividend to 424 and continue with: 4247 / 811

Moving on to step 4:
811 goes into 4247 5 times with a remainder of 192.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 4055 away from 4247, we end up with 192.
Bring next digit (4) of the dividend behind the 192 and repeat the process: 1924 / 811

Let's proceed to step 5:
The number 811 fits into 1924 2 times, leaving a remainder of 302.
Use 2 as the next digit of our solution. 
Result so far: 52.0
The remainder is 302 after subtracting 1622 from 1924.
Take the next digit (9) from the dividend and append it to 302, then repeat: 3029 / 811

Moving on to step 6:
The number 811 fits into 3029 3 times, leaving a remainder of 596.
The number 3 becomes the next digit in our result. 
Result so far: 523.0
Subtract 2433 from 3029 to get 596.
Append the next digit (5) from the dividend to 596 and continue with: 5965 / 811

Moving on to step 7:
The number 811 fits into 5965 7 times, leaving a remainder of 288.
Use 7 as the next digit of our solution. 
Result so far: 5237.0
Deduct 5677 from 5965 and we're left with 288.
Grab the next digit (0) from the dividend, add it to 288, then carry on: 2880 / 811

Advancing to step 8:
811 can be fit into 2880 3 times, resulting in a remainder of 447.
Use 3 as the next digit of our solution. 
Result so far: 52373.0
If we subtract 2433 from 2880, we get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 9:
811 can be fit into 4470 5 times, resulting in a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 52373.5
Subtract 4055 from 4470 to get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 10:
4150 divided by 811 is 5 with a remainder of 95.
The next digit of our result is 5. 
Result so far: 52373.55
Subtracting 4055 from 4150 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Our division results in 52373.55 with a remaining 0.095.
