We look at the division of 16603624 by 969 
The aim is to understand the frequency of 969 in 16603624.

Let's proceed to step 1:
969 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 969

Going ahead to step 2:
969 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 969

Moving on to step 3:
If we divide 166 by 969, we get 0 and a remainder of 166.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 166 and we're left with 166.
Append the next digit (0) from the dividend to 166 and continue with: 1660 / 969

Step 4:
969 can be fit into 1660 1 times, resulting in a remainder of 691.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 969 from 1660, we get 691.
Take the next digit (3) from the dividend and append it to 691, then repeat: 6913 / 969

Let's proceed to step 5:
969 goes into 6913 7 times with a remainder of 130.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 6783 from 6913, we get 130.
Append the next digit (6) from the dividend to 130 and continue with: 1306 / 969

Going ahead to step 6:
The number 969 fits into 1306 1 times, leaving a remainder of 337.
The next digit of our result is 1. 
Result so far: 171.0
If we subtract 969 from 1306, we get 337.
Include the next digit (2) from the dividend after 337, then repeat: 3372 / 969

Let's proceed to step 7:
969 goes into 3372 3 times with a remainder of 465.
The number 3 becomes the next digit in our result. 
Result so far: 1713.0
If we take 2907 away from 3372, we end up with 465.
Include the next digit (4) from the dividend after 465, then repeat: 4654 / 969

On to step 8:
969 goes into 4654 4 times with a remainder of 778.
The next digit of our result is 4. 
Result so far: 17134.0
Subtract 3876 from 4654 to get 778.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7780, and continue the process.

Step 9:
If we divide 7780 by 969, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 17134.8
The remainder is 28 after subtracting 7752 from 7780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
If we divide 280 by 969, we get 0 and a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 17134.8
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 11:
2800 divided by 969 is 2 with a remainder of 862.
Record the quotient 2 as the next digit in the result. 
Result so far: 17134.802
Deduct 1938 from 2800 and we're left with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

On to step 12:
969 goes into 8620 8 times with a remainder of 868.
Use 8 as the next digit of our solution. 
Result so far: 17134.8028
Subtracting 7752 from 8620 leaves us with 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Advancing to step 13:
If we divide 8680 by 969, we get 8 and a remainder of 928.
Record the quotient 8 as the next digit in the result. 
Result so far: 17134.80288
If we take 7752 away from 8680, we end up with 928.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9280, and continue the process.

After the division, we end up with 17134.80288 and a remainder of 0.000928.
