We're dividing 64248760 by 764 
The aim is to understand the frequency of 764 in 64248760.

Going ahead to step 1:
When dividing 6 by 764, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 764

Step 2:
When dividing 64 by 764, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (2) from the dividend, attach it to 64 and continue: 642 / 764

Let's proceed to step 3:
The number 764 fits into 642 0 times, leaving a remainder of 642.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 642, we get 642.
Fetch the next digit (4) from the dividend, attach it to 642 and continue: 6424 / 764

Let's proceed to step 4:
6424 divided by 764 is 8 with a remainder of 312.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 6112 from 6424 leaves us with 312.
Fetch the next digit (8) from the dividend, attach it to 312 and continue: 3128 / 764

Advancing to step 5:
The number 764 fits into 3128 4 times, leaving a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtracting 3056 from 3128 leaves us with 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 764

Advancing to step 6:
When dividing 727 by 764, we get 0 with a remainder of 727.
Write down 0 as next digit of the result. 
Result so far: 840.0
If we take 0 away from 727, we end up with 727.
Append the next digit (6) from the dividend to 727 and continue with: 7276 / 764

Going ahead to step 7:
When dividing 7276 by 764, we get 9 with a remainder of 400.
Put 9 as the next digit of the answer. 
Result so far: 8409.0
Subtracting 6876 from 7276 leaves us with 400.
Include the next digit (0) from the dividend after 400, then repeat: 4000 / 764

On to step 8:
4000 divided by 764 is 5 with a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 84095.0
Subtracting 3820 from 4000 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 9:
1800 divided by 764 is 2 with a remainder of 272.
Use 2 as the next digit of our solution. 
Result so far: 84095.2
Deduct 1528 from 1800 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 10:
If we divide 2720 by 764, we get 3 and a remainder of 428.
Use 3 as the next digit of our solution. 
Result so far: 84095.23
If we subtract 2292 from 2720, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 11:
When dividing 4280 by 764, we get 5 with a remainder of 460.
The number 5 becomes the next digit in our result. 
Result so far: 84095.235
Deduct 3820 from 4280 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 12:
764 goes into 4600 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 84095.2356
Subtracting 4584 from 4600 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
When dividing 160 by 764, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 84095.2356
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
When dividing 1600 by 764, we get 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 84095.235602
The remainder is 72 after subtracting 1528 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
720 divided by 764 is 0 with a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 84095.235602
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 16:
7200 divided by 764 is 9 with a remainder of 324.
The number 9 becomes the next digit in our result. 
Result so far: 84095.23560209
The remainder is 324 after subtracting 6876 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final result is 84095.23560209 with a remainder of 3.24e-07.
