We look at the division of 31043329 by 763 
The aim is to understand the frequency of 763 in 31043329.

On to step 1:
When dividing 3 by 763, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 763

Let's proceed to step 2:
If we divide 31 by 763, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (0) from the dividend to 31 and continue with: 310 / 763

Going ahead to step 3:
310 divided by 763 is 0 with a remainder of 310.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 310 leaves us with 310.
Include the next digit (4) from the dividend after 310, then repeat: 3104 / 763

On to step 4:
763 goes into 3104 4 times with a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3052 from 3104 and we're left with 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 763

Moving on to step 5:
If we divide 523 by 763, we get 0 and a remainder of 523.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 523, we get 523.
Append the next digit (3) from the dividend to 523 and continue with: 5233 / 763

Step 6:
The number 763 fits into 5233 6 times, leaving a remainder of 655.
The next digit of our result is 6. 
Result so far: 406.0
If we take 4578 away from 5233, we end up with 655.
Append the next digit (2) from the dividend to 655 and continue with: 6552 / 763

Step 7:
If we divide 6552 by 763, we get 8 and a remainder of 448.
The number 8 becomes the next digit in our result. 
Result so far: 4068.0
Subtracting 6104 from 6552 leaves us with 448.
Append the next digit (9) from the dividend to 448 and continue with: 4489 / 763

Step 8:
If we divide 4489 by 763, we get 5 and a remainder of 674.
Record the quotient 5 as the next digit in the result. 
Result so far: 40685.0
Subtracting 3815 from 4489 leaves us with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Advancing to step 9:
When dividing 6740 by 763, we get 8 with a remainder of 636.
Write down 8 as next digit of the result. 
Result so far: 40685.8
Subtracting 6104 from 6740 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 10:
When dividing 6360 by 763, we get 8 with a remainder of 256.
The number 8 becomes the next digit in our result. 
Result so far: 40685.88
Subtracting 6104 from 6360 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The quotient of the division is 40685.88, and the remainder is 0.256.
