26420407 divided by 810 
The aim is to understand the frequency of 810 in 26420407.

Step 1:
810 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 810

Moving on to step 2:
When dividing 26 by 810, we get 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Grab the next digit (4) from the dividend, add it to 26, then carry on: 264 / 810

Step 3:
When dividing 264 by 810, we get 0 with a remainder of 264.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 264, we end up with 264.
Include the next digit (2) from the dividend after 264, then repeat: 2642 / 810

On to step 4:
If we divide 2642 by 810, we get 3 and a remainder of 212.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2430 from 2642 and we're left with 212.
Grab the next digit (0) from the dividend, add it to 212, then carry on: 2120 / 810

Step 5:
810 can be fit into 2120 2 times, resulting in a remainder of 500.
The next digit of our result is 2. 
Result so far: 32.0
If we take 1620 away from 2120, we end up with 500.
Take the next digit (4) from the dividend and append it to 500, then repeat: 5004 / 810

Advancing to step 6:
810 can be fit into 5004 6 times, resulting in a remainder of 144.
Put 6 as the next digit of the answer. 
Result so far: 326.0
Subtracting 4860 from 5004 leaves us with 144.
Append the next digit (0) from the dividend to 144 and continue with: 1440 / 810

Step 7:
The number 810 fits into 1440 1 times, leaving a remainder of 630.
Write down 1 as next digit of the result. 
Result so far: 3261.0
The remainder is 630 after subtracting 810 from 1440.
Take the next digit (7) from the dividend and append it to 630, then repeat: 6307 / 810

Going ahead to step 8:
If we divide 6307 by 810, we get 7 and a remainder of 637.
The number 7 becomes the next digit in our result. 
Result so far: 32617.0
Subtracting 5670 from 6307 leaves us with 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Moving on to step 9:
If we divide 6370 by 810, we get 7 and a remainder of 700.
The number 7 becomes the next digit in our result. 
Result so far: 32617.7
Subtracting 5670 from 6370 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 10:
The number 810 fits into 7000 8 times, leaving a remainder of 520.
Write down 8 as next digit of the result. 
Result so far: 32617.78
Deduct 6480 from 7000 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 11:
When dividing 5200 by 810, we get 6 with a remainder of 340.
The next digit of our result is 6. 
Result so far: 32617.786
Deduct 4860 from 5200 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 12:
810 can be fit into 3400 4 times, resulting in a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 32617.7864
If we take 3240 away from 3400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 13:
If we divide 1600 by 810, we get 1 and a remainder of 790.
The number 1 becomes the next digit in our result. 
Result so far: 32617.78641
If we subtract 810 from 1600, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 14:
If we divide 7900 by 810, we get 9 and a remainder of 610.
Record the quotient 9 as the next digit in the result. 
Result so far: 32617.786419
If we take 7290 away from 7900, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 15:
810 goes into 6100 7 times with a remainder of 430.
Write down 7 as next digit of the result. 
Result so far: 32617.7864197
Subtract 5670 from 6100 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 16:
810 can be fit into 4300 5 times, resulting in a remainder of 250.
The next digit of our result is 5. 
Result so far: 32617.78641975
If we take 4050 away from 4300, we end up with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

After the division, we end up with 32617.78641975 and a remainder of 2.5e-07.
