We're dividing 91418325 by 426 
The aim is to understand the frequency of 426 in 91418325.

Moving on to step 1:
The number 426 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 426

Step 2:
426 goes into 91 0 times with a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Grab the next digit (4) from the dividend, add it to 91, then carry on: 914 / 426

Moving on to step 3:
914 divided by 426 is 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 852 from 914, we get 62.
Bring next digit (1) of the dividend behind the 62 and repeat the process: 621 / 426

Advancing to step 4:
If we divide 621 by 426, we get 1 and a remainder of 195.
The next digit of our result is 1. 
Result so far: 21.0
The remainder is 195 after subtracting 426 from 621.
Fetch the next digit (8) from the dividend, attach it to 195 and continue: 1958 / 426

On to step 5:
When dividing 1958 by 426, we get 4 with a remainder of 254.
Use 4 as the next digit of our solution. 
Result so far: 214.0
Deduct 1704 from 1958 and we're left with 254.
Grab the next digit (3) from the dividend, add it to 254, then carry on: 2543 / 426

On to step 6:
The number 426 fits into 2543 5 times, leaving a remainder of 413.
Use 5 as the next digit of our solution. 
Result so far: 2145.0
If we take 2130 away from 2543, we end up with 413.
Grab the next digit (2) from the dividend, add it to 413, then carry on: 4132 / 426

Let's proceed to step 7:
When dividing 4132 by 426, we get 9 with a remainder of 298.
The number 9 becomes the next digit in our result. 
Result so far: 21459.0
Subtract 3834 from 4132 to get 298.
Take the next digit (5) from the dividend and append it to 298, then repeat: 2985 / 426

Let's proceed to step 8:
426 can be fit into 2985 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 214597.0
Deduct 2982 from 2985 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
If we divide 30 by 426, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 214597.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
300 divided by 426 is 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 214597.0
If we subtract 0 from 300, we 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.

The final outcome is 214597.0, with a leftover of 0.3.
