We're dividing 990051 by 26 
The aim is to understand the frequency of 26 in 990051.

On to step 1:
When dividing 9 by 26, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 26

Moving on to step 2:
If we divide 99 by 26, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 21 after subtracting 78 from 99.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 26

On to step 3:
When dividing 210 by 26, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 38.0
Subtract 208 from 210 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 26

Going ahead to step 4:
When dividing 20 by 26, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 380.0
Subtracting 0 from 20 leaves us with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 26

Moving on to step 5:
When dividing 205 by 26, we get 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 3807.0
If we take 182 away from 205, we end up with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 26

Advancing to step 6:
231 divided by 26 is 8 with a remainder of 23.
The number 8 becomes the next digit in our result. 
Result so far: 38078.0
If we subtract 208 from 231, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
26 can be fit into 230 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 38078.8
If we subtract 208 from 230, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 8:
26 goes into 220 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 38078.88
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 38078.88, with a leftover of 0.012.
