We're dividing 355512 by 26 
The aim is to understand the frequency of 26 in 355512.

Going ahead to step 1:
When dividing 3 by 26, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 26

On to step 2:
35 divided by 26 is 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 26 away from 35, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 26

Going ahead to step 3:
When dividing 95 by 26, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 78 from 95 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 26

On to step 4:
26 can be fit into 175 6 times, resulting in a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 136.0
Subtracting 156 from 175 leaves us with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 26

Going ahead to step 5:
26 can be fit into 191 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 1367.0
If we subtract 182 from 191, we get 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 26

Step 6:
26 can be fit into 92 3 times, resulting in a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 13673.0
If we subtract 78 from 92, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
140 divided by 26 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 13673.5
If we take 130 away from 140, we end up 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:
If we divide 100 by 26, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 13673.53
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
220 divided by 26 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 13673.538
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.

Going ahead to step 10:
26 goes into 120 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 13673.5384
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
26 can be fit into 160 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 13673.53846
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
If we divide 40 by 26, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 13673.538461
Subtract 26 from 40 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
26 goes into 140 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 13673.5384615
If we take 130 away from 140, we end up 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.

On to step 14:
If we divide 100 by 26, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 13673.53846153
If we subtract 78 from 100, 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.

After the division, we end up with 13673.53846153 and a remainder of 2.2e-08.
