We divide 98769660 by 766
The aim is to understand the frequency of 766 in 98769660.

Step 1:
When dividing 9 by 766, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 766

Moving on to step 2:
If we divide 98 by 766, we get 0 and a remainder of 98.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Include the next digit (7) from the dividend after 98, then repeat: 987 / 766

Let's proceed to step 3:
The number 766 fits into 987 1 times, leaving a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 766 from 987 to get 221.
Fetch the next digit (6) from the dividend, attach it to 221 and continue: 2216 / 766

Let's proceed to step 4:
2216 divided by 766 is 2 with a remainder of 684.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 684 after subtracting 1532 from 2216.
Fetch the next digit (9) from the dividend, attach it to 684 and continue: 6849 / 766

Step 5:
If we divide 6849 by 766, we get 8 and a remainder of 721.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Deduct 6128 from 6849 and we're left with 721.
Append the next digit (6) from the dividend to 721 and continue with: 7216 / 766

Going ahead to step 6:
The number 766 fits into 7216 9 times, leaving a remainder of 322.
The next digit of our result is 9. 
Result so far: 1289.0
Subtracting 6894 from 7216 leaves us with 322.
Append the next digit (6) from the dividend to 322 and continue with: 3226 / 766

Advancing to step 7:
If we divide 3226 by 766, we get 4 and a remainder of 162.
Use 4 as the next digit of our solution. 
Result so far: 12894.0
If we subtract 3064 from 3226, we get 162.
Grab the next digit (0) from the dividend, add it to 162, then carry on: 1620 / 766

Advancing to step 8:
766 goes into 1620 2 times with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 128942.0
Subtracting 1532 from 1620 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 9:
The number 766 fits into 880 1 times, leaving a remainder of 114.
The next digit of our result is 1. 
Result so far: 128942.1
If we take 766 away from 880, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 10:
766 can be fit into 1140 1 times, resulting in a remainder of 374.
Put 1 as the next digit of the answer. 
Result so far: 128942.11
Subtract 766 from 1140 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

After the division, we end up with 128942.11 and a remainder of 0.374.
