537148 ÷ 26 
The aim is to understand the frequency of 26 in 537148.

Let's proceed to step 1:
The number 26 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 26

On to step 2:
If we divide 53 by 26, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 52 from 53 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 26

Going ahead to step 3:
26 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 26

Step 4:
26 goes into 171 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 206.0
Subtracting 156 from 171 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 26

Advancing to step 5:
154 divided by 26 is 5 with a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 2065.0
If we subtract 130 from 154, we get 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 26

Let's proceed to step 6:
248 divided by 26 is 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 20659.0
Deduct 234 from 248 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
When dividing 140 by 26, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 20659.5
Deduct 130 from 140 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
26 goes into 100 3 times with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 20659.53
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 9:
If we divide 220 by 26, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 20659.538
Deduct 208 from 220 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 10:
120 divided by 26 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 20659.5384
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
When dividing 160 by 26, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 20659.53846
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
26 can be fit into 40 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 20659.538461
If we take 26 away from 40, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
140 divided by 26 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 20659.5384615
Subtract 130 from 140 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
If we divide 100 by 26, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 20659.53846153
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 20659.53846153, with a leftover of 2.2e-08.
