We divide 82131211 by 154
The aim is to understand the frequency of 154 in 82131211.

On to step 1:
The number 154 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 154

Advancing to step 2:
82 divided by 154 is 0 with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 82 leaves us with 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 154

Moving on to step 3:
154 can be fit into 821 5 times, resulting in a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 770 from 821 to get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 154

Advancing to step 4:
154 goes into 513 3 times with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtracting 462 from 513 leaves us with 51.
Fetch the next digit (1) from the dividend, attach it to 51 and continue: 511 / 154

Let's proceed to step 5:
154 can be fit into 511 3 times, resulting in a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 533.0
Deduct 462 from 511 and we're left with 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 154

Going ahead to step 6:
The number 154 fits into 492 3 times, leaving a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 5333.0
If we subtract 462 from 492, we get 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 154

Going ahead to step 7:
301 divided by 154 is 1 with a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 53331.0
Subtracting 154 from 301 leaves us with 147.
Bring next digit (1) of the dividend behind the 147 and repeat the process: 1471 / 154

On to step 8:
1471 divided by 154 is 9 with a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 533319.0
Subtract 1386 from 1471 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 9:
154 can be fit into 850 5 times, resulting in a remainder of 80.
The next digit of our result is 5. 
Result so far: 533319.5
The remainder is 80 after subtracting 770 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 10:
800 divided by 154 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 533319.55
The remainder is 30 after subtracting 770 from 800.
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 533319.55, with a leftover of 0.03.
