43761387 ÷ 26 
The aim is to understand the frequency of 26 in 43761387.

Going ahead to step 1:
26 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 26

On to step 2:
43 divided by 26 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 26 from 43 leaves us with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 26

Step 3:
When dividing 177 by 26, we get 6 with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 156 from 177, we get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 26

Step 4:
The number 26 fits into 216 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
If we take 208 away from 216, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 26

Going ahead to step 5:
The number 26 fits into 81 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 1683.0
If we subtract 78 from 81, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 26

Advancing to step 6:
26 goes into 33 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 16831.0
If we subtract 26 from 33, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 26

Going ahead to step 7:
The number 26 fits into 78 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 168313.0
Subtracting 78 from 78 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 26

Let's proceed to step 8:
When dividing 7 by 26, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 1683130.0
If we subtract 0 from 7, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 9:
When dividing 70 by 26, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 1683130.2
Deduct 52 from 70 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
180 divided by 26 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 1683130.26
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
If we divide 240 by 26, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 1683130.269
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
When dividing 60 by 26, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 1683130.2692
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
26 goes into 80 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1683130.26923
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
26 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1683130.26923
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
When dividing 200 by 26, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 1683130.2692307
If we subtract 182 from 200, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 1683130.26923076
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 1683130.26923076 with a balance of 2.4e-08.
