20886296 divided by 289 
The aim is to understand the frequency of 289 in 20886296.

Going ahead to step 1:
2 divided by 289 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 289

Let's proceed to step 2:
289 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 289

Moving on to step 3:
The number 289 fits into 208 0 times, leaving a remainder of 208.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 208 after subtracting 0 from 208.
Append the next digit (8) from the dividend to 208 and continue with: 2088 / 289

Advancing to step 4:
289 goes into 2088 7 times with a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 65 after subtracting 2023 from 2088.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 289

On to step 5:
If we divide 656 by 289, we get 2 and a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 72.0
If we subtract 578 from 656, we get 78.
Take the next digit (2) from the dividend and append it to 78, then repeat: 782 / 289

Step 6:
The number 289 fits into 782 2 times, leaving a remainder of 204.
The next digit of our result is 2. 
Result so far: 722.0
Subtract 578 from 782 to get 204.
Include the next digit (9) from the dividend after 204, then repeat: 2049 / 289

Step 7:
The number 289 fits into 2049 7 times, leaving a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 7227.0
If we subtract 2023 from 2049, we get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 289

Let's proceed to step 8:
289 can be fit into 266 0 times, resulting in a remainder of 266.
The next digit of our result is 0. 
Result so far: 72270.0
Subtracting 0 from 266 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 9:
289 goes into 2660 9 times with a remainder of 59.
The next digit of our result is 9. 
Result so far: 72270.9
The remainder is 59 after subtracting 2601 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 10:
The number 289 fits into 590 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 72270.92
If we take 578 away from 590, 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 11:
If we divide 120 by 289, we get 0 and a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 72270.92
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
When dividing 1200 by 289, we get 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 72270.9204
Subtract 1156 from 1200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
When dividing 440 by 289, we get 1 with a remainder of 151.
The next digit of our result is 1. 
Result so far: 72270.92041
The remainder is 151 after subtracting 289 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Let's proceed to step 14:
When dividing 1510 by 289, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 72270.920415
Subtracting 1445 from 1510 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 15:
If we divide 650 by 289, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 72270.9204152
Subtract 578 from 650 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 16:
720 divided by 289 is 2 with a remainder of 142.
The next digit of our result is 2. 
Result so far: 72270.92041522
The remainder is 142 after subtracting 578 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

After the division, we end up with 72270.92041522 and a remainder of 1.42e-07.
