21708640 ÷ 269 
The aim is to understand the frequency of 269 in 21708640.

On to step 1:
When dividing 2 by 269, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 269

Let's proceed to step 2:
If we divide 21 by 269, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 269

Let's proceed to step 3:
269 can be fit into 217 0 times, resulting in a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 217 and we're left with 217.
Append the next digit (0) from the dividend to 217 and continue with: 2170 / 269

Step 4:
When dividing 2170 by 269, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 2152 away from 2170, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 269

On to step 5:
269 goes into 188 0 times with a remainder of 188.
Put 0 as the next digit of the answer. 
Result so far: 80.0
The remainder is 188 after subtracting 0 from 188.
Append the next digit (6) from the dividend to 188 and continue with: 1886 / 269

Advancing to step 6:
If we divide 1886 by 269, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 807.0
Subtract 1883 from 1886 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 269

Advancing to step 7:
The number 269 fits into 34 0 times, leaving a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 8070.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 269

Moving on to step 8:
269 goes into 340 1 times with a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 80701.0
Deduct 269 from 340 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
If we divide 710 by 269, we get 2 and a remainder of 172.
Record the quotient 2 as the next digit in the result. 
Result so far: 80701.2
Deduct 538 from 710 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 10:
269 goes into 1720 6 times with a remainder of 106.
The next digit of our result is 6. 
Result so far: 80701.26
If we take 1614 away from 1720, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 11:
269 goes into 1060 3 times with a remainder of 253.
The next digit of our result is 3. 
Result so far: 80701.263
If we take 807 away from 1060, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 12:
2530 divided by 269 is 9 with a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 80701.2639
Subtracting 2421 from 2530 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 13:
1090 divided by 269 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 80701.26394
If we take 1076 away from 1090, 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.

Let's proceed to step 14:
When dividing 140 by 269, we get 0 with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 80701.26394
If we take 0 away from 140, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 15:
269 goes into 1400 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 80701.2639405
The remainder is 55 after subtracting 1345 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 16:
550 divided by 269 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 80701.26394052
Subtract 538 from 550 to 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.

In conclusion, the division gives 80701.26394052 with a balance of 1.2e-08.
