77647848 ÷ 611 
The aim is to understand the frequency of 611 in 77647848.

Advancing to step 1:
611 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 611

Moving on to step 2:
If we divide 77 by 611, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 611

Step 3:
If we divide 776 by 611, we get 1 and a remainder of 165.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 611 from 776 leaves us with 165.
Bring next digit (4) of the dividend behind the 165 and repeat the process: 1654 / 611

Going ahead to step 4:
The number 611 fits into 1654 2 times, leaving a remainder of 432.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1222 from 1654 to get 432.
Take the next digit (7) from the dividend and append it to 432, then repeat: 4327 / 611

Step 5:
When dividing 4327 by 611, we get 7 with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we take 4277 away from 4327, we end up with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 611

On to step 6:
If we divide 508 by 611, we get 0 and a remainder of 508.
The next digit of our result is 0. 
Result so far: 1270.0
If we take 0 away from 508, we end up with 508.
Bring next digit (4) of the dividend behind the 508 and repeat the process: 5084 / 611

Step 7:
611 can be fit into 5084 8 times, resulting in a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 12708.0
Deduct 4888 from 5084 and we're left with 196.
Append the next digit (8) from the dividend to 196 and continue with: 1968 / 611

Advancing to step 8:
The number 611 fits into 1968 3 times, leaving a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 127083.0
Subtracting 1833 from 1968 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
If we divide 1350 by 611, we get 2 and a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 127083.2
If we take 1222 away from 1350, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 10:
611 goes into 1280 2 times with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 127083.22
Subtracting 1222 from 1280 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 127083.22 with a remainder of 0.058.
