We're dividing 98667886 by 771 
The aim is to understand the frequency of 771 in 98667886.

Advancing to step 1:
9 divided by 771 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 771

Step 2:
98 divided by 771 is 0 with a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Take the next digit (6) from the dividend and append it to 98, then repeat: 986 / 771

Step 3:
771 goes into 986 1 times with a remainder of 215.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 771 from 986, we get 215.
Take the next digit (6) from the dividend and append it to 215, then repeat: 2156 / 771

Let's proceed to step 4:
771 can be fit into 2156 2 times, resulting in a remainder of 614.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 1542 from 2156 leaves us with 614.
Bring next digit (7) of the dividend behind the 614 and repeat the process: 6147 / 771

Step 5:
771 goes into 6147 7 times with a remainder of 750.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we take 5397 away from 6147, we end up with 750.
Include the next digit (8) from the dividend after 750, then repeat: 7508 / 771

Moving on to step 6:
When dividing 7508 by 771, we get 9 with a remainder of 569.
Use 9 as the next digit of our solution. 
Result so far: 1279.0
If we subtract 6939 from 7508, we get 569.
Grab the next digit (8) from the dividend, add it to 569, then carry on: 5698 / 771

Let's proceed to step 7:
When dividing 5698 by 771, we get 7 with a remainder of 301.
Write down 7 as next digit of the result. 
Result so far: 12797.0
Subtracting 5397 from 5698 leaves us with 301.
Take the next digit (6) from the dividend and append it to 301, then repeat: 3016 / 771

Step 8:
771 can be fit into 3016 3 times, resulting in a remainder of 703.
Record the quotient 3 as the next digit in the result. 
Result so far: 127973.0
If we subtract 2313 from 3016, we get 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Moving on to step 9:
7030 divided by 771 is 9 with a remainder of 91.
Record the quotient 9 as the next digit in the result. 
Result so far: 127973.9
If we subtract 6939 from 7030, we get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 10:
771 goes into 910 1 times with a remainder of 139.
Write down 1 as next digit of the result. 
Result so far: 127973.91
Subtract 771 from 910 to get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 11:
1390 divided by 771 is 1 with a remainder of 619.
The number 1 becomes the next digit in our result. 
Result so far: 127973.911
Subtracting 771 from 1390 leaves us with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

After the division, we end up with 127973.911 and a remainder of 0.0619.
