65685795 ÷ 578 
The aim is to understand the frequency of 578 in 65685795.

Advancing to step 1:
578 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 578

Moving on to step 2:
65 divided by 578 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Append the next digit (6) from the dividend to 65 and continue with: 656 / 578

On to step 3:
If we divide 656 by 578, we get 1 and a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 578 from 656, we get 78.
Fetch the next digit (8) from the dividend, attach it to 78 and continue: 788 / 578

Moving on to step 4:
The number 578 fits into 788 1 times, leaving a remainder of 210.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 578 from 788 to get 210.
Append the next digit (5) from the dividend to 210 and continue with: 2105 / 578

Let's proceed to step 5:
When dividing 2105 by 578, we get 3 with a remainder of 371.
Use 3 as the next digit of our solution. 
Result so far: 113.0
Subtract 1734 from 2105 to get 371.
Bring next digit (7) of the dividend behind the 371 and repeat the process: 3717 / 578

Going ahead to step 6:
578 goes into 3717 6 times with a remainder of 249.
The number 6 becomes the next digit in our result. 
Result so far: 1136.0
The remainder is 249 after subtracting 3468 from 3717.
Bring next digit (9) of the dividend behind the 249 and repeat the process: 2499 / 578

Advancing to step 7:
578 can be fit into 2499 4 times, resulting in a remainder of 187.
Use 4 as the next digit of our solution. 
Result so far: 11364.0
If we take 2312 away from 2499, we end up with 187.
Include the next digit (5) from the dividend after 187, then repeat: 1875 / 578

On to step 8:
578 can be fit into 1875 3 times, resulting in a remainder of 141.
Record the quotient 3 as the next digit in the result. 
Result so far: 113643.0
If we subtract 1734 from 1875, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 9:
If we divide 1410 by 578, we get 2 and a remainder of 254.
The number 2 becomes the next digit in our result. 
Result so far: 113643.2
Subtract 1156 from 1410 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 10:
When dividing 2540 by 578, we get 4 with a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 113643.24
Deduct 2312 from 2540 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 11:
The number 578 fits into 2280 3 times, leaving a remainder of 546.
Put 3 as the next digit of the answer. 
Result so far: 113643.243
Subtracting 1734 from 2280 leaves us with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Advancing to step 12:
If we divide 5460 by 578, we get 9 and a remainder of 258.
Use 9 as the next digit of our solution. 
Result so far: 113643.2439
If we subtract 5202 from 5460, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 13:
When dividing 2580 by 578, we get 4 with a remainder of 268.
Put 4 as the next digit of the answer. 
Result so far: 113643.24394
If we subtract 2312 from 2580, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 14:
The number 578 fits into 2680 4 times, leaving a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 113643.243944
If we subtract 2312 from 2680, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 113643.243944 and a remainder of 3.68e-05.
