We look at the division of 23828807 by 154 
The aim is to understand the frequency of 154 in 23828807.

Moving on to step 1:
2 divided by 154 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 154

Going ahead to step 2:
154 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 154

Step 3:
When dividing 238 by 154, we get 1 with a remainder of 84.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 154 from 238 to get 84.
Fetch the next digit (2) from the dividend, attach it to 84 and continue: 842 / 154

Let's proceed to step 4:
If we divide 842 by 154, we get 5 and a remainder of 72.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 770 from 842, we get 72.
Grab the next digit (8) from the dividend, add it to 72, then carry on: 728 / 154

Going ahead to step 5:
728 divided by 154 is 4 with a remainder of 112.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
If we take 616 away from 728, we end up with 112.
Fetch the next digit (8) from the dividend, attach it to 112 and continue: 1128 / 154

Step 6:
When dividing 1128 by 154, we get 7 with a remainder of 50.
The next digit of our result is 7. 
Result so far: 1547.0
Subtract 1078 from 1128 to get 50.
Grab the next digit (0) from the dividend, add it to 50, then carry on: 500 / 154

On to step 7:
500 divided by 154 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 15473.0
Subtracting 462 from 500 leaves us with 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 154

Advancing to step 8:
When dividing 387 by 154, we get 2 with a remainder of 79.
The next digit of our result is 2. 
Result so far: 154732.0
Deduct 308 from 387 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 9:
154 can be fit into 790 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 154732.5
If we take 770 away from 790, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
154 can be fit into 200 1 times, resulting in a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 154732.51
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
If we divide 460 by 154, we get 2 and a remainder of 152.
Record the quotient 2 as the next digit in the result. 
Result so far: 154732.512
If we subtract 308 from 460, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 12:
If we divide 1520 by 154, we get 9 and a remainder of 134.
The number 9 becomes the next digit in our result. 
Result so far: 154732.5129
If we subtract 1386 from 1520, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 13:
154 can be fit into 1340 8 times, resulting in a remainder of 108.
The next digit of our result is 8. 
Result so far: 154732.51298
The remainder is 108 after subtracting 1232 from 1340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 14:
When dividing 1080 by 154, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 154732.512987
If we subtract 1078 from 1080, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 15:
When dividing 20 by 154, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 154732.512987
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 16:
The number 154 fits into 200 1 times, leaving a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 154732.51298701
The remainder is 46 after subtracting 154 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 154732.51298701 with a remainder of 4.6e-08.
