We're dividing 20206639 by 569 
The aim is to understand the frequency of 569 in 20206639.

Advancing to step 1:
When dividing 2 by 569, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 569

Advancing to step 2:
The number 569 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 569

Step 3:
The number 569 fits into 202 0 times, leaving a remainder of 202.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 202, we get 202.
Bring next digit (0) of the dividend behind the 202 and repeat the process: 2020 / 569

On to step 4:
569 goes into 2020 3 times with a remainder of 313.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1707 from 2020, we get 313.
Include the next digit (6) from the dividend after 313, then repeat: 3136 / 569

On to step 5:
When dividing 3136 by 569, we get 5 with a remainder of 291.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
If we take 2845 away from 3136, we end up with 291.
Bring next digit (6) of the dividend behind the 291 and repeat the process: 2916 / 569

On to step 6:
569 goes into 2916 5 times with a remainder of 71.
Record the quotient 5 as the next digit in the result. 
Result so far: 355.0
The remainder is 71 after subtracting 2845 from 2916.
Fetch the next digit (3) from the dividend, attach it to 71 and continue: 713 / 569

On to step 7:
713 divided by 569 is 1 with a remainder of 144.
Write down 1 as next digit of the result. 
Result so far: 3551.0
If we subtract 569 from 713, we get 144.
Take the next digit (9) from the dividend and append it to 144, then repeat: 1449 / 569

On to step 8:
When dividing 1449 by 569, we get 2 with a remainder of 311.
Put 2 as the next digit of the answer. 
Result so far: 35512.0
If we take 1138 away from 1449, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 9:
If we divide 3110 by 569, we get 5 and a remainder of 265.
Record the quotient 5 as the next digit in the result. 
Result so far: 35512.5
Subtract 2845 from 3110 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 10:
569 can be fit into 2650 4 times, resulting in a remainder of 374.
The next digit of our result is 4. 
Result so far: 35512.54
Deduct 2276 from 2650 and we're left with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 11:
569 can be fit into 3740 6 times, resulting in a remainder of 326.
The number 6 becomes the next digit in our result. 
Result so far: 35512.546
If we take 3414 away from 3740, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 12:
569 can be fit into 3260 5 times, resulting in a remainder of 415.
Put 5 as the next digit of the answer. 
Result so far: 35512.5465
If we take 2845 away from 3260, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 13:
569 can be fit into 4150 7 times, resulting in a remainder of 167.
Write down 7 as next digit of the result. 
Result so far: 35512.54657
Subtract 3983 from 4150 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 14:
569 can be fit into 1670 2 times, resulting in a remainder of 532.
Put 2 as the next digit of the answer. 
Result so far: 35512.546572
Subtracting 1138 from 1670 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 15:
When dividing 5320 by 569, we get 9 with a remainder of 199.
Put 9 as the next digit of the answer. 
Result so far: 35512.5465729
If we take 5121 away from 5320, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 16:
If we divide 1990 by 569, we get 3 and a remainder of 283.
Write down 3 as next digit of the result. 
Result so far: 35512.54657293
If we subtract 1707 from 1990, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

The final result is 35512.54657293 with a remainder of 2.83e-07.
