68734839 divided by 154 
The aim is to understand the frequency of 154 in 68734839.

Advancing to step 1:
If we divide 6 by 154, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 154

Step 2:
154 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Include the next digit (7) from the dividend after 68, then repeat: 687 / 154

Step 3:
If we divide 687 by 154, we get 4 and a remainder of 71.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 616 from 687 to get 71.
Include the next digit (3) from the dividend after 71, then repeat: 713 / 154

Advancing to step 4:
154 goes into 713 4 times with a remainder of 97.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Deduct 616 from 713 and we're left with 97.
Append the next digit (4) from the dividend to 97 and continue with: 974 / 154

Moving on to step 5:
The number 154 fits into 974 6 times, leaving a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 446.0
Deduct 924 from 974 and we're left with 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 154

Let's proceed to step 6:
If we divide 508 by 154, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 4463.0
Subtracting 462 from 508 leaves us with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 154

Let's proceed to step 7:
154 goes into 463 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 44633.0
Subtracting 462 from 463 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 154

Going ahead to step 8:
If we divide 19 by 154, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 446330.0
If we subtract 0 from 19, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
When dividing 190 by 154, we get 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 446330.1
The remainder is 36 after subtracting 154 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
The number 154 fits into 360 2 times, leaving a remainder of 52.
The next digit of our result is 2. 
Result so far: 446330.12
Deduct 308 from 360 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
If we divide 520 by 154, we get 3 and a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 446330.123
If we subtract 462 from 520, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 12:
154 goes into 580 3 times with a remainder of 118.
The next digit of our result is 3. 
Result so far: 446330.1233
Deduct 462 from 580 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The final outcome is 446330.1233, with a leftover of 0.00118.
