We divide 21014589 by 697
The aim is to understand the frequency of 697 in 21014589.

Going ahead to step 1:
2 divided by 697 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 697

Moving on to step 2:
697 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 697

Step 3:
The number 697 fits into 210 0 times, leaving a remainder of 210.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 210 leaves us with 210.
Bring next digit (1) of the dividend behind the 210 and repeat the process: 2101 / 697

Let's proceed to step 4:
The number 697 fits into 2101 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2091 from 2101 and we're left with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 697

Advancing to step 5:
697 can be fit into 104 0 times, resulting in a remainder of 104.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 104 leaves us with 104.
Take the next digit (5) from the dividend and append it to 104, then repeat: 1045 / 697

Moving on to step 6:
If we divide 1045 by 697, we get 1 and a remainder of 348.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
If we take 697 away from 1045, we end up with 348.
Include the next digit (8) from the dividend after 348, then repeat: 3488 / 697

Step 7:
When dividing 3488 by 697, we get 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 3015.0
If we subtract 3485 from 3488, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 697

Moving on to step 8:
If we divide 39 by 697, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 30150.0
If we subtract 0 from 39, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
390 divided by 697 is 0 with a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 30150.0
If we subtract 0 from 390, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
The number 697 fits into 3900 5 times, leaving a remainder of 415.
Put 5 as the next digit of the answer. 
Result so far: 30150.05
Subtracting 3485 from 3900 leaves us 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.

Advancing to step 11:
697 can be fit into 4150 5 times, resulting in a remainder of 665.
Write down 5 as next digit of the result. 
Result so far: 30150.055
Deduct 3485 from 4150 and we're left with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

After the division, we end up with 30150.055 and a remainder of 0.0665.
