We look at the division of 17731086 by 169 
The aim is to understand the frequency of 169 in 17731086.

Moving on to step 1:
If we divide 1 by 169, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 169

Step 2:
The number 169 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 169

Advancing to step 3:
The number 169 fits into 177 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 8 after subtracting 169 from 177.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 169

Step 4:
83 divided by 169 is 0 with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 83, we get 83.
Append the next digit (1) from the dividend to 83 and continue with: 831 / 169

Let's proceed to step 5:
169 goes into 831 4 times with a remainder of 155.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 676 away from 831, we end up with 155.
Include the next digit (0) from the dividend after 155, then repeat: 1550 / 169

Step 6:
1550 divided by 169 is 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 1049.0
If we subtract 1521 from 1550, we get 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 169

Let's proceed to step 7:
When dividing 298 by 169, we get 1 with a remainder of 129.
Record the quotient 1 as the next digit in the result. 
Result so far: 10491.0
Deduct 169 from 298 and we're left with 129.
Fetch the next digit (6) from the dividend, attach it to 129 and continue: 1296 / 169

On to step 8:
169 goes into 1296 7 times with a remainder of 113.
The number 7 becomes the next digit in our result. 
Result so far: 104917.0
If we take 1183 away from 1296, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 9:
169 goes into 1130 6 times with a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 104917.6
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.

Let's proceed to step 10:
169 can be fit into 1160 6 times, resulting in a remainder of 146.
The next digit of our result is 6. 
Result so far: 104917.66
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.

After the division, we end up with 104917.66 and a remainder of 0.146.
