15604099 ÷ 152 
The aim is to understand the frequency of 152 in 15604099.

Step 1:
If we divide 1 by 152, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
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 / 152

Let's proceed to step 2:
15 divided by 152 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
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 / 152

Advancing to step 3:
152 goes into 156 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 152 from 156 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 152

Moving on to step 4:
152 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 152

On to step 5:
152 can be fit into 404 2 times, resulting in a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 304 from 404 to get 100.
Bring next digit (0) of the dividend behind the 100 and repeat the process: 1000 / 152

Advancing to step 6:
If we divide 1000 by 152, we get 6 and a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 1026.0
If we subtract 912 from 1000, we get 88.
Bring next digit (9) of the dividend behind the 88 and repeat the process: 889 / 152

Let's proceed to step 7:
152 can be fit into 889 5 times, resulting in a remainder of 129.
Put 5 as the next digit of the answer. 
Result so far: 10265.0
Subtracting 760 from 889 leaves us with 129.
Grab the next digit (9) from the dividend, add it to 129, then carry on: 1299 / 152

Step 8:
If we divide 1299 by 152, we get 8 and a remainder of 83.
The number 8 becomes the next digit in our result. 
Result so far: 102658.0
The remainder is 83 after subtracting 1216 from 1299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Moving on to step 9:
152 goes into 830 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 102658.5
Subtract 760 from 830 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
The number 152 fits into 700 4 times, leaving a remainder of 92.
Record the quotient 4 as the next digit in the result. 
Result so far: 102658.54
If we subtract 608 from 700, 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.

Advancing to step 11:
If we divide 920 by 152, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 102658.546
Subtracting 912 from 920 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
80 divided by 152 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 102658.546
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
152 can be fit into 800 5 times, resulting in a remainder of 40.
The number 5 becomes the next digit in our result. 
Result so far: 102658.54605
Subtract 760 from 800 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
400 divided by 152 is 2 with a remainder of 96.
The number 2 becomes the next digit in our result. 
Result so far: 102658.546052
Subtracting 304 from 400 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 15:
960 divided by 152 is 6 with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 102658.5460526
Subtracting 912 from 960 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.

Let's proceed to step 16:
152 can be fit into 480 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 102658.54605263
Deduct 456 from 480 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 102658.54605263 with a balance of 2.4e-08.
