68255537 ÷ 809 
The aim is to understand the frequency of 809 in 68255537.

Let's proceed to step 1:
If we divide 6 by 809, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 809

On to step 2:
If we divide 68 by 809, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 809

Step 3:
809 can be fit into 682 0 times, resulting in a remainder of 682.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 682, we end up with 682.
Bring next digit (5) of the dividend behind the 682 and repeat the process: 6825 / 809

Moving on to step 4:
The number 809 fits into 6825 8 times, leaving a remainder of 353.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 6472 from 6825 leaves us with 353.
Grab the next digit (5) from the dividend, add it to 353, then carry on: 3535 / 809

Let's proceed to step 5:
The number 809 fits into 3535 4 times, leaving a remainder of 299.
The next digit of our result is 4. 
Result so far: 84.0
Deduct 3236 from 3535 and we're left with 299.
Bring next digit (5) of the dividend behind the 299 and repeat the process: 2995 / 809

On to step 6:
When dividing 2995 by 809, we get 3 with a remainder of 568.
The next digit of our result is 3. 
Result so far: 843.0
Subtract 2427 from 2995 to get 568.
Bring next digit (3) of the dividend behind the 568 and repeat the process: 5683 / 809

Going ahead to step 7:
5683 divided by 809 is 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 8437.0
Subtract 5663 from 5683 to get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 809

Step 8:
809 can be fit into 207 0 times, resulting in a remainder of 207.
The next digit of our result is 0. 
Result so far: 84370.0
Subtract 0 from 207 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 9:
The number 809 fits into 2070 2 times, leaving a remainder of 452.
Write down 2 as next digit of the result. 
Result so far: 84370.2
If we take 1618 away from 2070, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 10:
If we divide 4520 by 809, we get 5 and a remainder of 475.
The next digit of our result is 5. 
Result so far: 84370.25
Deduct 4045 from 4520 and we're left with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 11:
The number 809 fits into 4750 5 times, leaving a remainder of 705.
The next digit of our result is 5. 
Result so far: 84370.255
The remainder is 705 after subtracting 4045 from 4750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

The final outcome is 84370.255, with a leftover of 0.0705.
