We're dividing 35663281 by 766 
The aim is to understand the frequency of 766 in 35663281.

Moving on to step 1:
3 divided by 766 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 766

Let's proceed to step 2:
If we divide 35 by 766, we get 0 and a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 35 leaves us with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 766

Step 3:
766 goes into 356 0 times with a remainder of 356.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 356 to get 356.
Fetch the next digit (6) from the dividend, attach it to 356 and continue: 3566 / 766

Going ahead to step 4:
If we divide 3566 by 766, we get 4 and a remainder of 502.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3064 away from 3566, we end up with 502.
Bring next digit (3) of the dividend behind the 502 and repeat the process: 5023 / 766

Let's proceed to step 5:
766 can be fit into 5023 6 times, resulting in a remainder of 427.
Put 6 as the next digit of the answer. 
Result so far: 46.0
If we take 4596 away from 5023, we end up with 427.
Fetch the next digit (2) from the dividend, attach it to 427 and continue: 4272 / 766

Moving on to step 6:
If we divide 4272 by 766, we get 5 and a remainder of 442.
Write down 5 as next digit of the result. 
Result so far: 465.0
If we take 3830 away from 4272, we end up with 442.
Append the next digit (8) from the dividend to 442 and continue with: 4428 / 766

On to step 7:
If we divide 4428 by 766, we get 5 and a remainder of 598.
Write down 5 as next digit of the result. 
Result so far: 4655.0
Deduct 3830 from 4428 and we're left with 598.
Fetch the next digit (1) from the dividend, attach it to 598 and continue: 5981 / 766

Going ahead to step 8:
766 can be fit into 5981 7 times, resulting in a remainder of 619.
Write down 7 as next digit of the result. 
Result so far: 46557.0
Deduct 5362 from 5981 and we're left 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.

Moving on to step 9:
766 goes into 6190 8 times with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 46557.8
The remainder is 62 after subtracting 6128 from 6190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
The number 766 fits into 620 0 times, leaving a remainder of 620.
Use 0 as the next digit of our solution. 
Result so far: 46557.8
Subtract 0 from 620 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 11:
When dividing 6200 by 766, we get 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 46557.808
Subtract 6128 from 6200 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
766 can be fit into 720 0 times, resulting in a remainder of 720.
Record the quotient 0 as the next digit in the result. 
Result so far: 46557.808
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 13:
If we divide 7200 by 766, we get 9 and a remainder of 306.
Put 9 as the next digit of the answer. 
Result so far: 46557.80809
Subtract 6894 from 7200 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 14:
766 can be fit into 3060 3 times, resulting in a remainder of 762.
Put 3 as the next digit of the answer. 
Result so far: 46557.808093
Subtracting 2298 from 3060 leaves us with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Going ahead to step 15:
766 can be fit into 7620 9 times, resulting in a remainder of 726.
The next digit of our result is 9. 
Result so far: 46557.8080939
Deduct 6894 from 7620 and we're left with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Moving on to step 16:
If we divide 7260 by 766, we get 9 and a remainder of 366.
Put 9 as the next digit of the answer. 
Result so far: 46557.80809399
Deduct 6894 from 7260 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

The final outcome is 46557.80809399, with a leftover of 3.66e-07.
