We're dividing 30223931 by 169 
The aim is to understand the frequency of 169 in 30223931.

Moving on to step 1:
When dividing 3 by 169, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 169

Going ahead to step 2:
30 divided by 169 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 169

Advancing to step 3:
169 can be fit into 302 1 times, resulting in a remainder of 133.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 169 away from 302, we end up with 133.
Fetch the next digit (2) from the dividend, attach it to 133 and continue: 1332 / 169

Advancing to step 4:
169 can be fit into 1332 7 times, resulting in a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 1183 away from 1332, we end up with 149.
Fetch the next digit (3) from the dividend, attach it to 149 and continue: 1493 / 169

On to step 5:
The number 169 fits into 1493 8 times, leaving a remainder of 141.
Put 8 as the next digit of the answer. 
Result so far: 178.0
The remainder is 141 after subtracting 1352 from 1493.
Grab the next digit (9) from the dividend, add it to 141, then carry on: 1419 / 169

Let's proceed to step 6:
169 goes into 1419 8 times with a remainder of 67.
The number 8 becomes the next digit in our result. 
Result so far: 1788.0
Subtracting 1352 from 1419 leaves us with 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 169

Let's proceed to step 7:
169 goes into 673 3 times with a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 17883.0
If we take 507 away from 673, we end up with 166.
Include the next digit (1) from the dividend after 166, then repeat: 1661 / 169

Let's proceed to step 8:
The number 169 fits into 1661 9 times, leaving a remainder of 140.
The number 9 becomes the next digit in our result. 
Result so far: 178839.0
Subtracting 1521 from 1661 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 9:
The number 169 fits into 1400 8 times, leaving a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 178839.8
Subtracting 1352 from 1400 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 169, we get 2 with a remainder of 142.
The next digit of our result is 2. 
Result so far: 178839.82
The remainder is 142 after subtracting 338 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 11:
When dividing 1420 by 169, we get 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 178839.828
If we take 1352 away from 1420, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
680 divided by 169 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 178839.8284
Subtracting 676 from 680 leaves us 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.

Advancing to step 13:
40 divided by 169 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 178839.8284
Deduct 0 from 40 and we're left 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.

Going ahead to step 14:
169 goes into 400 2 times with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 178839.828402
Subtract 338 from 400 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 15:
620 divided by 169 is 3 with a remainder of 113.
Write down 3 as next digit of the result. 
Result so far: 178839.8284023
If we subtract 507 from 620, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Moving on to step 16:
1130 divided by 169 is 6 with a remainder of 116.
The next digit of our result is 6. 
Result so far: 178839.82840236
The remainder is 116 after subtracting 1014 from 1130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final outcome is 178839.82840236, with a leftover of 1.16e-07.
