We look at the division of 33155409 by 426 
The aim is to understand the frequency of 426 in 33155409.

Step 1:
The number 426 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 426

Advancing to step 2:
33 divided by 426 is 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 426

Let's proceed to step 3:
When dividing 331 by 426, we get 0 with a remainder of 331.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 331, we end up with 331.
Append the next digit (5) from the dividend to 331 and continue with: 3315 / 426

Let's proceed to step 4:
426 can be fit into 3315 7 times, resulting in a remainder of 333.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 2982 from 3315, we get 333.
Include the next digit (5) from the dividend after 333, then repeat: 3335 / 426

Step 5:
The number 426 fits into 3335 7 times, leaving a remainder of 353.
Write down 7 as next digit of the result. 
Result so far: 77.0
Deduct 2982 from 3335 and we're left with 353.
Include the next digit (4) from the dividend after 353, then repeat: 3534 / 426

Moving on to step 6:
The number 426 fits into 3534 8 times, leaving a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 778.0
Subtract 3408 from 3534 to get 126.
Grab the next digit (0) from the dividend, add it to 126, then carry on: 1260 / 426

On to step 7:
When dividing 1260 by 426, we get 2 with a remainder of 408.
Use 2 as the next digit of our solution. 
Result so far: 7782.0
Subtracting 852 from 1260 leaves us with 408.
Append the next digit (9) from the dividend to 408 and continue with: 4089 / 426

Going ahead to step 8:
426 can be fit into 4089 9 times, resulting in a remainder of 255.
Use 9 as the next digit of our solution. 
Result so far: 77829.0
If we subtract 3834 from 4089, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 9:
If we divide 2550 by 426, we get 5 and a remainder of 420.
Write down 5 as next digit of the result. 
Result so far: 77829.5
If we subtract 2130 from 2550, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
4200 divided by 426 is 9 with a remainder of 366.
Write down 9 as next digit of the result. 
Result so far: 77829.59
If we take 3834 away from 4200, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 11:
If we divide 3660 by 426, we get 8 and a remainder of 252.
Put 8 as the next digit of the answer. 
Result so far: 77829.598
If we take 3408 away from 3660, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 12:
The number 426 fits into 2520 5 times, leaving a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 77829.5985
Deduct 2130 from 2520 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 13:
The number 426 fits into 3900 9 times, leaving a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 77829.59859
If we subtract 3834 from 3900, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
The number 426 fits into 660 1 times, leaving a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 77829.598591
Subtract 426 from 660 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Step 15:
The number 426 fits into 2340 5 times, leaving a remainder of 210.
The number 5 becomes the next digit in our result. 
Result so far: 77829.5985915
Subtract 2130 from 2340 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 16:
The number 426 fits into 2100 4 times, leaving a remainder of 396.
Write down 4 as next digit of the result. 
Result so far: 77829.59859154
The remainder is 396 after subtracting 1704 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The quotient of the division is 77829.59859154, and the remainder is 3.96e-07.
