Let's divide 86881075 by 611
The aim is to understand the frequency of 611 in 86881075.

Advancing to step 1:
611 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
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 611

Going ahead to step 2:
611 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (8) from the dividend and append it to 86, then repeat: 868 / 611

Going ahead to step 3:
611 goes into 868 1 times with a remainder of 257.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 611 from 868, we get 257.
Take the next digit (8) from the dividend and append it to 257, then repeat: 2578 / 611

On to step 4:
611 goes into 2578 4 times with a remainder of 134.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2444 from 2578, we get 134.
Take the next digit (1) from the dividend and append it to 134, then repeat: 1341 / 611

On to step 5:
611 goes into 1341 2 times with a remainder of 119.
Record the quotient 2 as the next digit in the result. 
Result so far: 142.0
Deduct 1222 from 1341 and we're left with 119.
Include the next digit (0) from the dividend after 119, then repeat: 1190 / 611

On to step 6:
611 goes into 1190 1 times with a remainder of 579.
Put 1 as the next digit of the answer. 
Result so far: 1421.0
The remainder is 579 after subtracting 611 from 1190.
Take the next digit (7) from the dividend and append it to 579, then repeat: 5797 / 611

Let's proceed to step 7:
When dividing 5797 by 611, we get 9 with a remainder of 298.
Write down 9 as next digit of the result. 
Result so far: 14219.0
Deduct 5499 from 5797 and we're left with 298.
Append the next digit (5) from the dividend to 298 and continue with: 2985 / 611

Advancing to step 8:
611 can be fit into 2985 4 times, resulting in a remainder of 541.
Record the quotient 4 as the next digit in the result. 
Result so far: 142194.0
Subtract 2444 from 2985 to get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 9:
611 can be fit into 5410 8 times, resulting in a remainder of 522.
Use 8 as the next digit of our solution. 
Result so far: 142194.8
If we subtract 4888 from 5410, we get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 10:
611 goes into 5220 8 times with a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 142194.88
The remainder is 332 after subtracting 4888 from 5220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

After the division, we end up with 142194.88 and a remainder of 0.332.
