63878884 divided by 26 
The aim is to understand the frequency of 26 in 63878884.

On to step 1:
If we divide 6 by 26, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 26

Let's proceed to step 2:
When dividing 63 by 26, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 52 from 63 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 26

Advancing to step 3:
118 divided by 26 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 104 from 118, we get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 26

On to step 4:
26 can be fit into 147 5 times, resulting in a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 245.0
The remainder is 17 after subtracting 130 from 147.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 26

Advancing to step 5:
26 goes into 178 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 2456.0
The remainder is 22 after subtracting 156 from 178.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 26

On to step 6:
If we divide 228 by 26, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 24568.0
If we subtract 208 from 228, we get 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 26

Advancing to step 7:
If we divide 208 by 26, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 245688.0
Subtract 208 from 208 to get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 26

Advancing to step 8:
26 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 2456880.0
Deduct 0 from 4 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.

Advancing to step 9:
40 divided by 26 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 2456880.1
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.

Moving on to step 10:
If we divide 140 by 26, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 2456880.15
Subtracting 130 from 140 leaves us 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.

Let's proceed to step 11:
100 divided by 26 is 3 with a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 2456880.153
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.

Moving on to step 12:
When dividing 220 by 26, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 2456880.1538
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.

On to step 13:
When dividing 120 by 26, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 2456880.15384
Deduct 104 from 120 and we're left 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.

Advancing to step 14:
26 can be fit into 160 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 2456880.153846
Subtracting 156 from 160 leaves us 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 15:
The number 26 fits into 40 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 2456880.1538461
If we subtract 26 from 40, 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.

On to step 16:
26 goes into 140 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 2456880.15384615
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.

The quotient of the division is 2456880.15384615, and the remainder is 1e-08.
