We look at the division of 72580223 by 152 
The aim is to understand the frequency of 152 in 72580223.

Moving on to step 1:
When dividing 7 by 152, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 152

Let's proceed to step 2:
72 divided by 152 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 152

Step 3:
725 divided by 152 is 4 with a remainder of 117.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 117 after subtracting 608 from 725.
Grab the next digit (8) from the dividend, add it to 117, then carry on: 1178 / 152

Moving on to step 4:
When dividing 1178 by 152, we get 7 with a remainder of 114.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 1064 away from 1178, we end up with 114.
Take the next digit (0) from the dividend and append it to 114, then repeat: 1140 / 152

Step 5:
If we divide 1140 by 152, we get 7 and a remainder of 76.
The next digit of our result is 7. 
Result so far: 477.0
If we subtract 1064 from 1140, we get 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 152

Step 6:
The number 152 fits into 762 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 4775.0
Subtracting 760 from 762 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 152

Let's proceed to step 7:
152 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 47750.0
Deduct 0 from 22 and we're left with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 152

Let's proceed to step 8:
152 can be fit into 223 1 times, resulting in a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 477501.0
Subtract 152 from 223 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Step 9:
The number 152 fits into 710 4 times, leaving a remainder of 102.
Write down 4 as next digit of the result. 
Result so far: 477501.4
If we take 608 away from 710, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 10:
152 goes into 1020 6 times with a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 477501.46
Deduct 912 from 1020 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 11:
152 goes into 1080 7 times with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 477501.467
Subtracting 1064 from 1080 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 12:
When dividing 160 by 152, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 477501.4671
If we take 152 away from 160, we end up 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.

Moving on to step 13:
When dividing 80 by 152, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 477501.4671
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
The number 152 fits into 800 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 477501.467105
Deduct 760 from 800 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.

On to step 15:
The number 152 fits into 400 2 times, leaving a remainder of 96.
Use 2 as the next digit of our solution. 
Result so far: 477501.4671052
The remainder is 96 after subtracting 304 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 16:
152 can be fit into 960 6 times, resulting in a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 477501.46710526
If we take 912 away from 960, we end up 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.

After the division, we end up with 477501.46710526 and a remainder of 4.8e-08.
