We look at the division of 8636910 by 769 
The aim is to understand the frequency of 769 in 8636910.

Going ahead to step 1:
769 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 769

Going ahead to step 2:
769 can be fit into 86 0 times, resulting in a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Bring next digit (3) of the dividend behind the 86 and repeat the process: 863 / 769

Going ahead to step 3:
The number 769 fits into 863 1 times, leaving a remainder of 94.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 769 from 863 leaves us with 94.
Include the next digit (6) from the dividend after 94, then repeat: 946 / 769

Let's proceed to step 4:
769 goes into 946 1 times with a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 769 from 946 to get 177.
Fetch the next digit (9) from the dividend, attach it to 177 and continue: 1779 / 769

Step 5:
If we divide 1779 by 769, we get 2 and a remainder of 241.
Use 2 as the next digit of our solution. 
Result so far: 112.0
The remainder is 241 after subtracting 1538 from 1779.
Fetch the next digit (1) from the dividend, attach it to 241 and continue: 2411 / 769

Going ahead to step 6:
2411 divided by 769 is 3 with a remainder of 104.
Use 3 as the next digit of our solution. 
Result so far: 1123.0
The remainder is 104 after subtracting 2307 from 2411.
Take the next digit (0) from the dividend and append it to 104, then repeat: 1040 / 769

Advancing to step 7:
If we divide 1040 by 769, we get 1 and a remainder of 271.
The number 1 becomes the next digit in our result. 
Result so far: 11231.0
Deduct 769 from 1040 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Advancing to step 8:
The number 769 fits into 2710 3 times, leaving a remainder of 403.
Record the quotient 3 as the next digit in the result. 
Result so far: 11231.3
Subtract 2307 from 2710 to get 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 9:
769 goes into 4030 5 times with a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 11231.35
The remainder is 185 after subtracting 3845 from 4030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
If we divide 1850 by 769, we get 2 and a remainder of 312.
Put 2 as the next digit of the answer. 
Result so far: 11231.352
The remainder is 312 after subtracting 1538 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 11:
3120 divided by 769 is 4 with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 11231.3524
Deduct 3076 from 3120 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
If we divide 440 by 769, we get 0 and a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 11231.3524
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 13:
If we divide 4400 by 769, we get 5 and a remainder of 555.
Record the quotient 5 as the next digit in the result. 
Result so far: 11231.352405
If we take 3845 away from 4400, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Going ahead to step 14:
769 goes into 5550 7 times with a remainder of 167.
The next digit of our result is 7. 
Result so far: 11231.3524057
The remainder is 167 after subtracting 5383 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Step 15:
769 can be fit into 1670 2 times, resulting in a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 11231.35240572
If we take 1538 away from 1670, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 11231.35240572 with a remainder of 1.32e-07.
