52228920 divided by 813 
The aim is to understand the frequency of 813 in 52228920.

Step 1:
If we divide 5 by 813, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 813

Let's proceed to step 2:
52 divided by 813 is 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 813

Moving on to step 3:
813 goes into 522 0 times with a remainder of 522.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 522, we end up with 522.
Fetch the next digit (2) from the dividend, attach it to 522 and continue: 5222 / 813

On to step 4:
5222 divided by 813 is 6 with a remainder of 344.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 4878 from 5222 and we're left with 344.
Bring next digit (8) of the dividend behind the 344 and repeat the process: 3448 / 813

On to step 5:
813 goes into 3448 4 times with a remainder of 196.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Deduct 3252 from 3448 and we're left with 196.
Take the next digit (9) from the dividend and append it to 196, then repeat: 1969 / 813

Let's proceed to step 6:
If we divide 1969 by 813, we get 2 and a remainder of 343.
The next digit of our result is 2. 
Result so far: 642.0
If we subtract 1626 from 1969, we get 343.
Include the next digit (2) from the dividend after 343, then repeat: 3432 / 813

Going ahead to step 7:
If we divide 3432 by 813, we get 4 and a remainder of 180.
The number 4 becomes the next digit in our result. 
Result so far: 6424.0
If we subtract 3252 from 3432, we get 180.
Grab the next digit (0) from the dividend, add it to 180, then carry on: 1800 / 813

On to step 8:
If we divide 1800 by 813, we get 2 and a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 64242.0
If we take 1626 away from 1800, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 9:
If we divide 1740 by 813, we get 2 and a remainder of 114.
The next digit of our result is 2. 
Result so far: 64242.2
If we take 1626 away from 1740, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
If we divide 1140 by 813, we get 1 and a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 64242.21
Subtract 813 from 1140 to get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Moving on to step 11:
813 can be fit into 3270 4 times, resulting in a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 64242.214
If we take 3252 away from 3270, 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.

Going ahead to step 12:
813 goes into 180 0 times with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 64242.214
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
813 can be fit into 1800 2 times, resulting in a remainder of 174.
Write down 2 as next digit of the result. 
Result so far: 64242.21402
Subtract 1626 from 1800 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Moving on to step 14:
When dividing 1740 by 813, we get 2 with a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 64242.214022
Subtract 1626 from 1740 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

The final result is 64242.214022 with a remainder of 1.14e-05.
