78335806 ÷ 609 
The aim is to understand the frequency of 609 in 78335806.

Moving on to step 1:
7 divided by 609 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 609

Step 2:
The number 609 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 609

On to step 3:
When dividing 783 by 609, we get 1 with a remainder of 174.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 609 from 783 to get 174.
Include the next digit (3) from the dividend after 174, then repeat: 1743 / 609

On to step 4:
When dividing 1743 by 609, we get 2 with a remainder of 525.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1218 from 1743 to get 525.
Append the next digit (5) from the dividend to 525 and continue with: 5255 / 609

On to step 5:
If we divide 5255 by 609, we get 8 and a remainder of 383.
The next digit of our result is 8. 
Result so far: 128.0
If we take 4872 away from 5255, we end up with 383.
Append the next digit (8) from the dividend to 383 and continue with: 3838 / 609

On to step 6:
3838 divided by 609 is 6 with a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 1286.0
Subtracting 3654 from 3838 leaves us with 184.
Take the next digit (0) from the dividend and append it to 184, then repeat: 1840 / 609

Step 7:
The number 609 fits into 1840 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 12863.0
If we subtract 1827 from 1840, we get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 609

Step 8:
If we divide 136 by 609, we get 0 and a remainder of 136.
Write down 0 as next digit of the result. 
Result so far: 128630.0
Subtract 0 from 136 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 9:
The number 609 fits into 1360 2 times, leaving a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 128630.2
The remainder is 142 after subtracting 1218 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 10:
609 can be fit into 1420 2 times, resulting in a remainder of 202.
Use 2 as the next digit of our solution. 
Result so far: 128630.22
Deduct 1218 from 1420 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

In conclusion, the division gives 128630.22 with a balance of 0.202.
