We're dividing 11687812 by 326 
The aim is to understand the frequency of 326 in 11687812.

Step 1:
When dividing 1 by 326, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 326

Moving on to step 2:
The number 326 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 326

Moving on to step 3:
326 goes into 116 0 times with a remainder of 116.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 116 after subtracting 0 from 116.
Bring next digit (8) of the dividend behind the 116 and repeat the process: 1168 / 326

Going ahead to step 4:
The number 326 fits into 1168 3 times, leaving a remainder of 190.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 978 from 1168, we get 190.
Take the next digit (7) from the dividend and append it to 190, then repeat: 1907 / 326

Advancing to step 5:
1907 divided by 326 is 5 with a remainder of 277.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
The remainder is 277 after subtracting 1630 from 1907.
Bring next digit (8) of the dividend behind the 277 and repeat the process: 2778 / 326

Moving on to step 6:
326 can be fit into 2778 8 times, resulting in a remainder of 170.
Put 8 as the next digit of the answer. 
Result so far: 358.0
If we take 2608 away from 2778, we end up with 170.
Take the next digit (1) from the dividend and append it to 170, then repeat: 1701 / 326

Advancing to step 7:
When dividing 1701 by 326, we get 5 with a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 3585.0
Deduct 1630 from 1701 and we're left with 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 326

Moving on to step 8:
326 goes into 712 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 35852.0
Subtracting 652 from 712 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
326 goes into 600 1 times with a remainder of 274.
The number 1 becomes the next digit in our result. 
Result so far: 35852.1
Subtract 326 from 600 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 10:
If we divide 2740 by 326, we get 8 and a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 35852.18
Subtract 2608 from 2740 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 11:
When dividing 1320 by 326, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 35852.184
If we take 1304 away from 1320, we end up 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.

Moving on to step 12:
160 divided by 326 is 0 with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 35852.184
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
If we divide 1600 by 326, we get 4 and a remainder of 296.
The next digit of our result is 4. 
Result so far: 35852.18404
If we take 1304 away from 1600, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 14:
2960 divided by 326 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 35852.184049
If we take 2934 away from 2960, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 15:
The number 326 fits into 260 0 times, leaving a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 35852.184049
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 16:
2600 divided by 326 is 7 with a remainder of 318.
Record the quotient 7 as the next digit in the result. 
Result so far: 35852.18404907
Deduct 2282 from 2600 and we're left with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

The quotient of the division is 35852.18404907, and the remainder is 3.18e-07.
