We look at the division of 85773551 by 616 
The aim is to understand the frequency of 616 in 85773551.

Let's proceed to step 1:
616 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 616

Let's proceed to step 2:
616 can be fit into 85 0 times, resulting in a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Bring next digit (7) of the dividend behind the 85 and repeat the process: 857 / 616

Step 3:
When dividing 857 by 616, we get 1 with a remainder of 241.
The next digit of our result is 1. 
Result so far: 1.0
If we take 616 away from 857, we end up with 241.
Fetch the next digit (7) from the dividend, attach it to 241 and continue: 2417 / 616

Step 4:
2417 divided by 616 is 3 with a remainder of 569.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1848 from 2417 leaves us with 569.
Bring next digit (3) of the dividend behind the 569 and repeat the process: 5693 / 616

Moving on to step 5:
616 goes into 5693 9 times with a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
If we subtract 5544 from 5693, we get 149.
Include the next digit (5) from the dividend after 149, then repeat: 1495 / 616

Let's proceed to step 6:
616 can be fit into 1495 2 times, resulting in a remainder of 263.
Write down 2 as next digit of the result. 
Result so far: 1392.0
Subtracting 1232 from 1495 leaves us with 263.
Append the next digit (5) from the dividend to 263 and continue with: 2635 / 616

Step 7:
The number 616 fits into 2635 4 times, leaving a remainder of 171.
Put 4 as the next digit of the answer. 
Result so far: 13924.0
If we subtract 2464 from 2635, we get 171.
Include the next digit (1) from the dividend after 171, then repeat: 1711 / 616

On to step 8:
1711 divided by 616 is 2 with a remainder of 479.
The number 2 becomes the next digit in our result. 
Result so far: 139242.0
Subtracting 1232 from 1711 leaves us with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Let's proceed to step 9:
When dividing 4790 by 616, we get 7 with a remainder of 478.
The number 7 becomes the next digit in our result. 
Result so far: 139242.7
If we take 4312 away from 4790, we end up with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 10:
When dividing 4780 by 616, we get 7 with a remainder of 468.
The number 7 becomes the next digit in our result. 
Result so far: 139242.77
Deduct 4312 from 4780 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

The final result is 139242.77 with a remainder of 0.468.
