We look at the division of 26836382 by 681 
The aim is to understand the frequency of 681 in 26836382.

Step 1:
When dividing 2 by 681, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 681

Advancing to step 2:
When dividing 26 by 681, we get 0 with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 681

Step 3:
If we divide 268 by 681, we get 0 and a remainder of 268.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 268 after subtracting 0 from 268.
Fetch the next digit (3) from the dividend, attach it to 268 and continue: 2683 / 681

Let's proceed to step 4:
The number 681 fits into 2683 3 times, leaving a remainder of 640.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 640 after subtracting 2043 from 2683.
Take the next digit (6) from the dividend and append it to 640, then repeat: 6406 / 681

Let's proceed to step 5:
6406 divided by 681 is 9 with a remainder of 277.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtracting 6129 from 6406 leaves us with 277.
Bring next digit (3) of the dividend behind the 277 and repeat the process: 2773 / 681

Going ahead to step 6:
If we divide 2773 by 681, we get 4 and a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 394.0
The remainder is 49 after subtracting 2724 from 2773.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 681

On to step 7:
When dividing 498 by 681, we get 0 with a remainder of 498.
Record the quotient 0 as the next digit in the result. 
Result so far: 3940.0
Subtract 0 from 498 to get 498.
Grab the next digit (2) from the dividend, add it to 498, then carry on: 4982 / 681

Let's proceed to step 8:
681 can be fit into 4982 7 times, resulting in a remainder of 215.
Use 7 as the next digit of our solution. 
Result so far: 39407.0
Subtracting 4767 from 4982 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 9:
When dividing 2150 by 681, we get 3 with a remainder of 107.
Record the quotient 3 as the next digit in the result. 
Result so far: 39407.3
If we take 2043 away from 2150, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Advancing to step 10:
681 goes into 1070 1 times with a remainder of 389.
The number 1 becomes the next digit in our result. 
Result so far: 39407.31
The remainder is 389 after subtracting 681 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Going ahead to step 11:
3890 divided by 681 is 5 with a remainder of 485.
The next digit of our result is 5. 
Result so far: 39407.315
If we subtract 3405 from 3890, we get 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 12:
The number 681 fits into 4850 7 times, leaving a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 39407.3157
Subtracting 4767 from 4850 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 13:
If we divide 830 by 681, we get 1 and a remainder of 149.
Write down 1 as next digit of the result. 
Result so far: 39407.31571
The remainder is 149 after subtracting 681 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 14:
1490 divided by 681 is 2 with a remainder of 128.
The next digit of our result is 2. 
Result so far: 39407.315712
Subtract 1362 from 1490 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 15:
The number 681 fits into 1280 1 times, leaving a remainder of 599.
Use 1 as the next digit of our solution. 
Result so far: 39407.3157121
If we take 681 away from 1280, we end up with 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

On to step 16:
5990 divided by 681 is 8 with a remainder of 542.
Put 8 as the next digit of the answer. 
Result so far: 39407.31571218
Deduct 5448 from 5990 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

After the division, we end up with 39407.31571218 and a remainder of 5.42e-07.
