18450815 ÷ 153 
The aim is to understand the frequency of 153 in 18450815.

Let's proceed to step 1:
The number 153 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 153

Let's proceed to step 2:
153 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 153

Let's proceed to step 3:
153 goes into 184 1 times with a remainder of 31.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 153 from 184 and we're left with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 153

On to step 4:
315 divided by 153 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 306 from 315 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 153

Advancing to step 5:
When dividing 90 by 153, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we subtract 0 from 90, we get 90.
Bring next digit (8) of the dividend behind the 90 and repeat the process: 908 / 153

Step 6:
153 can be fit into 908 5 times, resulting in a remainder of 143.
Put 5 as the next digit of the answer. 
Result so far: 1205.0
Subtracting 765 from 908 leaves us with 143.
Fetch the next digit (1) from the dividend, attach it to 143 and continue: 1431 / 153

Moving on to step 7:
1431 divided by 153 is 9 with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 12059.0
Deduct 1377 from 1431 and we're left with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 153

Step 8:
545 divided by 153 is 3 with a remainder of 86.
Record the quotient 3 as the next digit in the result. 
Result so far: 120593.0
If we subtract 459 from 545, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
153 goes into 860 5 times with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 120593.5
Subtracting 765 from 860 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 10:
153 goes into 950 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 120593.56
The remainder is 32 after subtracting 918 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
153 can be fit into 320 2 times, resulting in a remainder of 14.
The next digit of our result is 2. 
Result so far: 120593.562
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
153 can be fit into 140 0 times, resulting in a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 120593.562
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
153 goes into 1400 9 times with a remainder of 23.
The next digit of our result is 9. 
Result so far: 120593.56209
Deduct 1377 from 1400 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
230 divided by 153 is 1 with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 120593.562091
Subtract 153 from 230 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 15:
770 divided by 153 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 120593.5620915
If we take 765 away from 770, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 16:
If we divide 50 by 153, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 120593.5620915
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 120593.5620915 with a balance of 5e-08.
