12490326 ÷ 169 
The aim is to understand the frequency of 169 in 12490326.

Advancing to step 1:
The number 169 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 169

Moving on to step 2:
The number 169 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 169

On to step 3:
If we divide 124 by 169, we get 0 and a remainder of 124.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 169

Moving on to step 4:
When dividing 1249 by 169, we get 7 with a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 1183 from 1249 leaves us with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 169

Going ahead to step 5:
The number 169 fits into 660 3 times, leaving a remainder of 153.
Write down 3 as next digit of the result. 
Result so far: 73.0
If we subtract 507 from 660, we get 153.
Fetch the next digit (3) from the dividend, attach it to 153 and continue: 1533 / 169

Let's proceed to step 6:
The number 169 fits into 1533 9 times, leaving a remainder of 12.
The next digit of our result is 9. 
Result so far: 739.0
If we subtract 1521 from 1533, we get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 169

Step 7:
When dividing 122 by 169, we get 0 with a remainder of 122.
Use 0 as the next digit of our solution. 
Result so far: 7390.0
Subtracting 0 from 122 leaves us with 122.
Append the next digit (6) from the dividend to 122 and continue with: 1226 / 169

Step 8:
1226 divided by 169 is 7 with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 73907.0
Subtract 1183 from 1226 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
The number 169 fits into 430 2 times, leaving a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 73907.2
If we subtract 338 from 430, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 10:
920 divided by 169 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 73907.25
The remainder is 75 after subtracting 845 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
When dividing 750 by 169, we get 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 73907.254
Deduct 676 from 750 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 12:
The number 169 fits into 740 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 73907.2544
Subtracting 676 from 740 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 73907.2544 and a remainder of 0.00064.
