We look at the division of 73229386 by 766 
The aim is to understand the frequency of 766 in 73229386.

On to step 1:
When dividing 7 by 766, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 766

Moving on to step 2:
73 divided by 766 is 0 with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Fetch the next digit (2) from the dividend, attach it to 73 and continue: 732 / 766

Advancing to step 3:
If we divide 732 by 766, we get 0 and a remainder of 732.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 732 after subtracting 0 from 732.
Take the next digit (2) from the dividend and append it to 732, then repeat: 7322 / 766

Let's proceed to step 4:
766 can be fit into 7322 9 times, resulting in a remainder of 428.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 6894 from 7322 to get 428.
Grab the next digit (9) from the dividend, add it to 428, then carry on: 4289 / 766

Moving on to step 5:
766 can be fit into 4289 5 times, resulting in a remainder of 459.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we subtract 3830 from 4289, we get 459.
Grab the next digit (3) from the dividend, add it to 459, then carry on: 4593 / 766

Advancing to step 6:
766 can be fit into 4593 5 times, resulting in a remainder of 763.
The next digit of our result is 5. 
Result so far: 955.0
The remainder is 763 after subtracting 3830 from 4593.
Append the next digit (8) from the dividend to 763 and continue with: 7638 / 766

Moving on to step 7:
When dividing 7638 by 766, we get 9 with a remainder of 744.
Use 9 as the next digit of our solution. 
Result so far: 9559.0
If we take 6894 away from 7638, we end up with 744.
Fetch the next digit (6) from the dividend, attach it to 744 and continue: 7446 / 766

On to step 8:
If we divide 7446 by 766, we get 9 and a remainder of 552.
Write down 9 as next digit of the result. 
Result so far: 95599.0
Deduct 6894 from 7446 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Step 9:
5520 divided by 766 is 7 with a remainder of 158.
Write down 7 as next digit of the result. 
Result so far: 95599.7
Subtracting 5362 from 5520 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
If we divide 1580 by 766, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 95599.72
If we take 1532 away from 1580, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
The number 766 fits into 480 0 times, leaving a remainder of 480.
The next digit of our result is 0. 
Result so far: 95599.72
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 12:
The number 766 fits into 4800 6 times, leaving a remainder of 204.
Put 6 as the next digit of the answer. 
Result so far: 95599.7206
The remainder is 204 after subtracting 4596 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 13:
When dividing 2040 by 766, we get 2 with a remainder of 508.
Put 2 as the next digit of the answer. 
Result so far: 95599.72062
Subtracting 1532 from 2040 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Let's proceed to step 14:
The number 766 fits into 5080 6 times, leaving a remainder of 484.
Put 6 as the next digit of the answer. 
Result so far: 95599.720626
If we subtract 4596 from 5080, we get 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 15:
The number 766 fits into 4840 6 times, leaving a remainder of 244.
Use 6 as the next digit of our solution. 
Result so far: 95599.7206266
If we take 4596 away from 4840, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The final result is 95599.7206266 with a remainder of 2.44e-06.
