64471154 divided by 766 
The aim is to understand the frequency of 766 in 64471154.

Moving on to step 1:
The number 766 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 766

Moving on to step 2:
The number 766 fits into 64 0 times, leaving a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 766

Going ahead to step 3:
The number 766 fits into 644 0 times, leaving a remainder of 644.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 644, we get 644.
Bring next digit (7) of the dividend behind the 644 and repeat the process: 6447 / 766

Let's proceed to step 4:
766 can be fit into 6447 8 times, resulting in a remainder of 319.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 319 after subtracting 6128 from 6447.
Take the next digit (1) from the dividend and append it to 319, then repeat: 3191 / 766

Moving on to step 5:
When dividing 3191 by 766, we get 4 with a remainder of 127.
The next digit of our result is 4. 
Result so far: 84.0
Subtract 3064 from 3191 to get 127.
Grab the next digit (1) from the dividend, add it to 127, then carry on: 1271 / 766

Step 6:
766 goes into 1271 1 times with a remainder of 505.
Put 1 as the next digit of the answer. 
Result so far: 841.0
If we take 766 away from 1271, we end up with 505.
Grab the next digit (5) from the dividend, add it to 505, then carry on: 5055 / 766

Moving on to step 7:
766 goes into 5055 6 times with a remainder of 459.
Record the quotient 6 as the next digit in the result. 
Result so far: 8416.0
The remainder is 459 after subtracting 4596 from 5055.
Bring next digit (4) of the dividend behind the 459 and repeat the process: 4594 / 766

On to step 8:
The number 766 fits into 4594 5 times, leaving a remainder of 764.
Put 5 as the next digit of the answer. 
Result so far: 84165.0
Subtracting 3830 from 4594 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Let's proceed to step 9:
7640 divided by 766 is 9 with a remainder of 746.
Record the quotient 9 as the next digit in the result. 
Result so far: 84165.9
Deduct 6894 from 7640 and we're left with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Moving on to step 10:
If we divide 7460 by 766, we get 9 and a remainder of 566.
Write down 9 as next digit of the result. 
Result so far: 84165.99
The remainder is 566 after subtracting 6894 from 7460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

The final outcome is 84165.99, with a leftover of 0.566.
