65581819 ÷ 616 
The aim is to understand the frequency of 616 in 65581819.

Going ahead to step 1:
616 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 616

Going ahead to step 2:
65 divided by 616 is 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 616

Going ahead to step 3:
616 can be fit into 655 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 616 away from 655, we end up with 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 616

On to step 4:
If we divide 398 by 616, we get 0 and a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 398 after subtracting 0 from 398.
Grab the next digit (1) from the dividend, add it to 398, then carry on: 3981 / 616

Advancing to step 5:
3981 divided by 616 is 6 with a remainder of 285.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we subtract 3696 from 3981, we get 285.
Fetch the next digit (8) from the dividend, attach it to 285 and continue: 2858 / 616

Moving on to step 6:
The number 616 fits into 2858 4 times, leaving a remainder of 394.
Write down 4 as next digit of the result. 
Result so far: 1064.0
If we subtract 2464 from 2858, we get 394.
Bring next digit (1) of the dividend behind the 394 and repeat the process: 3941 / 616

Going ahead to step 7:
616 goes into 3941 6 times with a remainder of 245.
The number 6 becomes the next digit in our result. 
Result so far: 10646.0
The remainder is 245 after subtracting 3696 from 3941.
Grab the next digit (9) from the dividend, add it to 245, then carry on: 2459 / 616

Let's proceed to step 8:
When dividing 2459 by 616, we get 3 with a remainder of 611.
Put 3 as the next digit of the answer. 
Result so far: 106463.0
The remainder is 611 after subtracting 1848 from 2459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

On to step 9:
When dividing 6110 by 616, we get 9 with a remainder of 566.
Write down 9 as next digit of the result. 
Result so far: 106463.9
Deduct 5544 from 6110 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Let's proceed to step 10:
5660 divided by 616 is 9 with a remainder of 116.
Record the quotient 9 as the next digit in the result. 
Result so far: 106463.99
If we subtract 5544 from 5660, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 106463.99 and a remainder of 0.116.
