21449670 divided by 511 
The aim is to understand the frequency of 511 in 21449670.

Let's proceed to step 1:
2 divided by 511 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 511

Advancing to step 2:
21 divided by 511 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 511

Advancing to step 3:
When dividing 214 by 511, we get 0 with a remainder of 214.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 214, we get 214.
Fetch the next digit (4) from the dividend, attach it to 214 and continue: 2144 / 511

Let's proceed to step 4:
When dividing 2144 by 511, we get 4 with a remainder of 100.
The next digit of our result is 4. 
Result so far: 4.0
If we take 2044 away from 2144, we end up with 100.
Bring next digit (9) of the dividend behind the 100 and repeat the process: 1009 / 511

Moving on to step 5:
When dividing 1009 by 511, we get 1 with a remainder of 498.
Write down 1 as next digit of the result. 
Result so far: 41.0
Subtract 511 from 1009 to get 498.
Take the next digit (6) from the dividend and append it to 498, then repeat: 4986 / 511

Advancing to step 6:
The number 511 fits into 4986 9 times, leaving a remainder of 387.
The number 9 becomes the next digit in our result. 
Result so far: 419.0
If we subtract 4599 from 4986, we get 387.
Fetch the next digit (7) from the dividend, attach it to 387 and continue: 3877 / 511

On to step 7:
If we divide 3877 by 511, we get 7 and a remainder of 300.
The next digit of our result is 7. 
Result so far: 4197.0
Deduct 3577 from 3877 and we're left with 300.
Append the next digit (0) from the dividend to 300 and continue with: 3000 / 511

Going ahead to step 8:
When dividing 3000 by 511, we get 5 with a remainder of 445.
The number 5 becomes the next digit in our result. 
Result so far: 41975.0
If we take 2555 away from 3000, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 9:
The number 511 fits into 4450 8 times, leaving a remainder of 362.
The number 8 becomes the next digit in our result. 
Result so far: 41975.8
Deduct 4088 from 4450 and we're left with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 10:
511 can be fit into 3620 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 41975.87
Subtract 3577 from 3620 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 11:
If we divide 430 by 511, we get 0 and a remainder of 430.
Put 0 as the next digit of the answer. 
Result so far: 41975.87
Deduct 0 from 430 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 12:
If we divide 4300 by 511, we get 8 and a remainder of 212.
Record the quotient 8 as the next digit in the result. 
Result so far: 41975.8708
The remainder is 212 after subtracting 4088 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 13:
The number 511 fits into 2120 4 times, leaving a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 41975.87084
The remainder is 76 after subtracting 2044 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
When dividing 760 by 511, we get 1 with a remainder of 249.
The number 1 becomes the next digit in our result. 
Result so far: 41975.870841
The remainder is 249 after subtracting 511 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 15:
The number 511 fits into 2490 4 times, leaving a remainder of 446.
Write down 4 as next digit of the result. 
Result so far: 41975.8708414
The remainder is 446 after subtracting 2044 from 2490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Step 16:
When dividing 4460 by 511, we get 8 with a remainder of 372.
The next digit of our result is 8. 
Result so far: 41975.87084148
If we take 4088 away from 4460, we end up with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

The final result is 41975.87084148 with a remainder of 3.72e-07.
