28121024 divided by 154 
The aim is to understand the frequency of 154 in 28121024.

Going ahead to step 1:
154 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 154

Going ahead to step 2:
28 divided by 154 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 154

Moving on to step 3:
281 divided by 154 is 1 with a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 154 from 281, we get 127.
Grab the next digit (2) from the dividend, add it to 127, then carry on: 1272 / 154

Advancing to step 4:
154 goes into 1272 8 times with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 1232 from 1272, we get 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 154

Advancing to step 5:
When dividing 401 by 154, we get 2 with a remainder of 93.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
Deduct 308 from 401 and we're left with 93.
Bring next digit (0) of the dividend behind the 93 and repeat the process: 930 / 154

Moving on to step 6:
930 divided by 154 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 1826.0
Subtracting 924 from 930 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 154

Let's proceed to step 7:
When dividing 62 by 154, we get 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 18260.0
If we take 0 away from 62, we end up with 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 154

Going ahead to step 8:
154 goes into 624 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 182604.0
The remainder is 8 after subtracting 616 from 624.
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 9:
The number 154 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 182604.0
Subtracting 0 from 80 leaves us 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.

Moving on to step 10:
800 divided by 154 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 182604.05
Subtract 770 from 800 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 154 fits into 300 1 times, leaving a remainder of 146.
Record the quotient 1 as the next digit in the result. 
Result so far: 182604.051
Subtract 154 from 300 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 12:
The number 154 fits into 1460 9 times, leaving a remainder of 74.
Put 9 as the next digit of the answer. 
Result so far: 182604.0519
Subtract 1386 from 1460 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 13:
When dividing 740 by 154, we get 4 with a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 182604.05194
Subtract 616 from 740 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 14:
If we divide 1240 by 154, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 182604.051948
If we take 1232 away from 1240, 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.

Advancing to step 15:
When dividing 80 by 154, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 182604.051948
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.

Advancing to step 16:
154 goes into 800 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 182604.05194805
Deduct 770 from 800 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 182604.05194805, with a leftover of 3e-08.
