33097791 ÷ 426 
The aim is to understand the frequency of 426 in 33097791.

On to step 1:
When dividing 3 by 426, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 426

On to step 2:
426 goes into 33 0 times with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 426

Step 3:
426 can be fit into 330 0 times, resulting in a remainder of 330.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 330 and we're left with 330.
Include the next digit (9) from the dividend after 330, then repeat: 3309 / 426

Moving on to step 4:
If we divide 3309 by 426, we get 7 and a remainder of 327.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 327 after subtracting 2982 from 3309.
Append the next digit (7) from the dividend to 327 and continue with: 3277 / 426

On to step 5:
426 can be fit into 3277 7 times, resulting in a remainder of 295.
The next digit of our result is 7. 
Result so far: 77.0
The remainder is 295 after subtracting 2982 from 3277.
Fetch the next digit (7) from the dividend, attach it to 295 and continue: 2957 / 426

Advancing to step 6:
2957 divided by 426 is 6 with a remainder of 401.
The number 6 becomes the next digit in our result. 
Result so far: 776.0
Subtract 2556 from 2957 to get 401.
Fetch the next digit (9) from the dividend, attach it to 401 and continue: 4019 / 426

Moving on to step 7:
426 can be fit into 4019 9 times, resulting in a remainder of 185.
Put 9 as the next digit of the answer. 
Result so far: 7769.0
If we subtract 3834 from 4019, we get 185.
Include the next digit (1) from the dividend after 185, then repeat: 1851 / 426

Step 8:
If we divide 1851 by 426, we get 4 and a remainder of 147.
Record the quotient 4 as the next digit in the result. 
Result so far: 77694.0
Subtracting 1704 from 1851 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 9:
426 goes into 1470 3 times with a remainder of 192.
The next digit of our result is 3. 
Result so far: 77694.3
Deduct 1278 from 1470 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 10:
The number 426 fits into 1920 4 times, leaving a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 77694.34
If we take 1704 away from 1920, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 11:
If we divide 2160 by 426, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 77694.345
If we take 2130 away from 2160, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
If we divide 300 by 426, we get 0 and a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 77694.345
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 13:
3000 divided by 426 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 77694.34507
If we subtract 2982 from 3000, 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.

Advancing to step 14:
If we divide 180 by 426, we get 0 and a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 77694.34507
Subtracting 0 from 180 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 15:
The number 426 fits into 1800 4 times, leaving a remainder of 96.
Write down 4 as next digit of the result. 
Result so far: 77694.3450704
If we take 1704 away from 1800, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
960 divided by 426 is 2 with a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 77694.34507042
Deduct 852 from 960 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final result is 77694.34507042 with a remainder of 1.08e-07.
