We look at the division of 23885450 by 169 
The aim is to understand the frequency of 169 in 23885450.

Let's proceed to step 1:
169 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 169

Moving on to step 2:
23 divided by 169 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 169

On to step 3:
The number 169 fits into 238 1 times, leaving a remainder of 69.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 69 after subtracting 169 from 238.
Take the next digit (8) from the dividend and append it to 69, then repeat: 698 / 169

On to step 4:
The number 169 fits into 698 4 times, leaving a remainder of 22.
The next digit of our result is 4. 
Result so far: 14.0
If we take 676 away from 698, we end up with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 169

Moving on to step 5:
169 goes into 225 1 times with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Deduct 169 from 225 and we're left with 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 169

Let's proceed to step 6:
169 can be fit into 564 3 times, resulting in a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 1413.0
Subtract 507 from 564 to get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 169

On to step 7:
The number 169 fits into 575 3 times, leaving a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 14133.0
The remainder is 68 after subtracting 507 from 575.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 169

Advancing to step 8:
169 can be fit into 680 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 141334.0
Deduct 676 from 680 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 169 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 141334.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 169 fits into 400 2 times, leaving a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 141334.02
Subtracting 338 from 400 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
If we divide 620 by 169, we get 3 and a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 141334.023
The remainder is 113 after subtracting 507 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Let's proceed to step 12:
169 can be fit into 1130 6 times, resulting in a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 141334.0236
If we take 1014 away from 1130, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 13:
1160 divided by 169 is 6 with a remainder of 146.
Record the quotient 6 as the next digit in the result. 
Result so far: 141334.02366
Subtract 1014 from 1160 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The quotient of the division is 141334.02366, and the remainder is 0.000146.
