We're dividing 13090577 by 764 
The aim is to understand the frequency of 764 in 13090577.

On to step 1:
If we divide 1 by 764, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 764

Moving on to step 2:
13 divided by 764 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 764

Let's proceed to step 3:
764 can be fit into 130 0 times, resulting in a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 130, we end up with 130.
Include the next digit (9) from the dividend after 130, then repeat: 1309 / 764

Advancing to step 4:
If we divide 1309 by 764, we get 1 and a remainder of 545.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 764 from 1309 to get 545.
Append the next digit (0) from the dividend to 545 and continue with: 5450 / 764

On to step 5:
5450 divided by 764 is 7 with a remainder of 102.
The next digit of our result is 7. 
Result so far: 17.0
The remainder is 102 after subtracting 5348 from 5450.
Bring next digit (5) of the dividend behind the 102 and repeat the process: 1025 / 764

Moving on to step 6:
When dividing 1025 by 764, we get 1 with a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 171.0
If we take 764 away from 1025, we end up with 261.
Include the next digit (7) from the dividend after 261, then repeat: 2617 / 764

Moving on to step 7:
2617 divided by 764 is 3 with a remainder of 325.
The number 3 becomes the next digit in our result. 
Result so far: 1713.0
Subtracting 2292 from 2617 leaves us with 325.
Include the next digit (7) from the dividend after 325, then repeat: 3257 / 764

Step 8:
When dividing 3257 by 764, we get 4 with a remainder of 201.
The next digit of our result is 4. 
Result so far: 17134.0
If we take 3056 away from 3257, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

On to step 9:
2010 divided by 764 is 2 with a remainder of 482.
Record the quotient 2 as the next digit in the result. 
Result so far: 17134.2
Deduct 1528 from 2010 and we're left with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

On to step 10:
The number 764 fits into 4820 6 times, leaving a remainder of 236.
Write down 6 as next digit of the result. 
Result so far: 17134.26
If we take 4584 away from 4820, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Let's proceed to step 11:
764 goes into 2360 3 times with a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 17134.263
The remainder is 68 after subtracting 2292 from 2360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 12:
680 divided by 764 is 0 with a remainder of 680.
Record the quotient 0 as the next digit in the result. 
Result so far: 17134.263
Deduct 0 from 680 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 13:
When dividing 6800 by 764, we get 8 with a remainder of 688.
Use 8 as the next digit of our solution. 
Result so far: 17134.26308
If we subtract 6112 from 6800, we get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Step 14:
764 goes into 6880 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 17134.263089
Subtracting 6876 from 6880 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 15:
If we divide 40 by 764, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 17134.263089
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
The number 764 fits into 400 0 times, leaving a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 17134.263089
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 17134.263089 and a remainder of 4e-07.
