Let's divide 15660459 by 153
The aim is to understand the frequency of 153 in 15660459.

Moving on to step 1:
If we divide 1 by 153, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 153

Moving on to step 2:
153 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 153

Advancing to step 3:
156 divided by 153 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 153 from 156 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 153

Let's proceed to step 4:
If we divide 36 by 153, we get 0 and a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 36, we end up with 36.
Include the next digit (0) from the dividend after 36, then repeat: 360 / 153

On to step 5:
When dividing 360 by 153, we get 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtract 306 from 360 to get 54.
Include the next digit (4) from the dividend after 54, then repeat: 544 / 153

On to step 6:
153 can be fit into 544 3 times, resulting in a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 1023.0
The remainder is 85 after subtracting 459 from 544.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 153

Advancing to step 7:
855 divided by 153 is 5 with a remainder of 90.
Record the quotient 5 as the next digit in the result. 
Result so far: 10235.0
Deduct 765 from 855 and we're left with 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 153

Advancing to step 8:
When dividing 909 by 153, we get 5 with a remainder of 144.
Use 5 as the next digit of our solution. 
Result so far: 102355.0
The remainder is 144 after subtracting 765 from 909.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 9:
The number 153 fits into 1440 9 times, leaving a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 102355.9
If we take 1377 away from 1440, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 10:
When dividing 630 by 153, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 102355.94
If we subtract 612 from 630, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
180 divided by 153 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 102355.941
If we subtract 153 from 180, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
The number 153 fits into 270 1 times, leaving a remainder of 117.
Use 1 as the next digit of our solution. 
Result so far: 102355.9411
If we take 153 away from 270, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

After the division, we end up with 102355.9411 and a remainder of 0.00117.
