881566 divided by 26 
The aim is to understand the frequency of 26 in 881566.

Moving on to step 1:
26 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 26

Step 2:
The number 26 fits into 88 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 78 from 88 and we're left with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 26

Going ahead to step 3:
101 divided by 26 is 3 with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 78 from 101, we get 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 26

Going ahead to step 4:
235 divided by 26 is 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 339.0
The remainder is 1 after subtracting 234 from 235.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 26

Let's proceed to step 5:
26 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 3390.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 26

Let's proceed to step 6:
When dividing 166 by 26, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 33906.0
Deduct 156 from 166 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.

On to step 7:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 33906.3
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.

Advancing to step 8:
220 divided by 26 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 33906.38
If we take 208 away from 220, we end up 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 9:
120 divided by 26 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 33906.384
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
The number 26 fits into 160 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 33906.3846
If we subtract 156 from 160, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
40 divided by 26 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 33906.38461
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.

Advancing to step 12:
The number 26 fits into 140 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 33906.384615
If we subtract 130 from 140, we 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.

Going ahead to step 13:
When dividing 100 by 26, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 33906.3846153
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 14:
220 divided by 26 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 33906.38461538
If we subtract 208 from 220, we 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.

Our division results in 33906.38461538 with a remaining 1.2e-08.
