We look at the division of 20929809 by 699 
The aim is to understand the frequency of 699 in 20929809.

Going ahead to step 1:
The number 699 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 699

Moving on to step 2:
20 divided by 699 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 699

On to step 3:
When dividing 209 by 699, we get 0 with a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 209 after subtracting 0 from 209.
Grab the next digit (2) from the dividend, add it to 209, then carry on: 2092 / 699

Advancing to step 4:
The number 699 fits into 2092 2 times, leaving a remainder of 694.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1398 from 2092, we get 694.
Take the next digit (9) from the dividend and append it to 694, then repeat: 6949 / 699

Step 5:
The number 699 fits into 6949 9 times, leaving a remainder of 658.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 6291 from 6949 leaves us with 658.
Include the next digit (8) from the dividend after 658, then repeat: 6588 / 699

Let's proceed to step 6:
699 can be fit into 6588 9 times, resulting in a remainder of 297.
Write down 9 as next digit of the result. 
Result so far: 299.0
Subtract 6291 from 6588 to get 297.
Grab the next digit (0) from the dividend, add it to 297, then carry on: 2970 / 699

On to step 7:
699 can be fit into 2970 4 times, resulting in a remainder of 174.
The number 4 becomes the next digit in our result. 
Result so far: 2994.0
Subtract 2796 from 2970 to get 174.
Grab the next digit (9) from the dividend, add it to 174, then carry on: 1749 / 699

Let's proceed to step 8:
If we divide 1749 by 699, we get 2 and a remainder of 351.
Record the quotient 2 as the next digit in the result. 
Result so far: 29942.0
The remainder is 351 after subtracting 1398 from 1749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 9:
The number 699 fits into 3510 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 29942.5
Deduct 3495 from 3510 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
If we divide 150 by 699, we get 0 and a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 29942.5
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
1500 divided by 699 is 2 with a remainder of 102.
The next digit of our result is 2. 
Result so far: 29942.502
Subtracting 1398 from 1500 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Moving on to step 12:
When dividing 1020 by 699, we get 1 with a remainder of 321.
Put 1 as the next digit of the answer. 
Result so far: 29942.5021
The remainder is 321 after subtracting 699 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 13:
If we divide 3210 by 699, we get 4 and a remainder of 414.
Use 4 as the next digit of our solution. 
Result so far: 29942.50214
The remainder is 414 after subtracting 2796 from 3210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Going ahead to step 14:
If we divide 4140 by 699, we get 5 and a remainder of 645.
Put 5 as the next digit of the answer. 
Result so far: 29942.502145
If we take 3495 away from 4140, we end up with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

On to step 15:
If we divide 6450 by 699, we get 9 and a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 29942.5021459
If we subtract 6291 from 6450, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Let's proceed to step 16:
699 can be fit into 1590 2 times, resulting in a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 29942.50214592
If we subtract 1398 from 1590, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

After the division, we end up with 29942.50214592 and a remainder of 1.92e-07.
