We look at the division of 52285802 by 809 
The aim is to understand the frequency of 809 in 52285802.

Step 1:
When dividing 5 by 809, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 809

On to step 2:
When dividing 52 by 809, we get 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Grab the next digit (2) from the dividend, add it to 52, then carry on: 522 / 809

Step 3:
When dividing 522 by 809, we get 0 with a remainder of 522.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 522, we end up with 522.
Take the next digit (8) from the dividend and append it to 522, then repeat: 5228 / 809

Step 4:
The number 809 fits into 5228 6 times, leaving a remainder of 374.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 4854 from 5228 to get 374.
Take the next digit (5) from the dividend and append it to 374, then repeat: 3745 / 809

Moving on to step 5:
3745 divided by 809 is 4 with a remainder of 509.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 3236 from 3745 leaves us with 509.
Bring next digit (8) of the dividend behind the 509 and repeat the process: 5098 / 809

Let's proceed to step 6:
809 goes into 5098 6 times with a remainder of 244.
The next digit of our result is 6. 
Result so far: 646.0
Subtracting 4854 from 5098 leaves us with 244.
Take the next digit (0) from the dividend and append it to 244, then repeat: 2440 / 809

Let's proceed to step 7:
If we divide 2440 by 809, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 6463.0
Subtracting 2427 from 2440 leaves us with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 809

Let's proceed to step 8:
132 divided by 809 is 0 with a remainder of 132.
Record the quotient 0 as the next digit in the result. 
Result so far: 64630.0
If we take 0 away from 132, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
809 can be fit into 1320 1 times, resulting in a remainder of 511.
Put 1 as the next digit of the answer. 
Result so far: 64630.1
Deduct 809 from 1320 and we're left with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Advancing to step 10:
5110 divided by 809 is 6 with a remainder of 256.
The number 6 becomes the next digit in our result. 
Result so far: 64630.16
If we take 4854 away from 5110, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 11:
809 can be fit into 2560 3 times, resulting in a remainder of 133.
Use 3 as the next digit of our solution. 
Result so far: 64630.163
If we take 2427 away from 2560, we end up with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 12:
1330 divided by 809 is 1 with a remainder of 521.
Write down 1 as next digit of the result. 
Result so far: 64630.1631
The remainder is 521 after subtracting 809 from 1330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

Moving on to step 13:
When dividing 5210 by 809, we get 6 with a remainder of 356.
Write down 6 as next digit of the result. 
Result so far: 64630.16316
If we take 4854 away from 5210, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 14:
3560 divided by 809 is 4 with a remainder of 324.
Record the quotient 4 as the next digit in the result. 
Result so far: 64630.163164
Subtracting 3236 from 3560 leaves us with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 15:
3240 divided by 809 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 64630.1631644
Deduct 3236 from 3240 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 64630.1631644 with a balance of 4e-08.
