54124936 divided by 354 
The aim is to understand the frequency of 354 in 54124936.

Step 1:
The number 354 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 354

On to step 2:
When dividing 54 by 354, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 354

Moving on to step 3:
If we divide 541 by 354, we get 1 and a remainder of 187.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 354 from 541 and we're left with 187.
Bring next digit (2) of the dividend behind the 187 and repeat the process: 1872 / 354

Going ahead to step 4:
354 goes into 1872 5 times with a remainder of 102.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 1770 from 1872, we get 102.
Append the next digit (4) from the dividend to 102 and continue with: 1024 / 354

On to step 5:
The number 354 fits into 1024 2 times, leaving a remainder of 316.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Subtracting 708 from 1024 leaves us with 316.
Bring next digit (9) of the dividend behind the 316 and repeat the process: 3169 / 354

Advancing to step 6:
354 goes into 3169 8 times with a remainder of 337.
Put 8 as the next digit of the answer. 
Result so far: 1528.0
Subtract 2832 from 3169 to get 337.
Append the next digit (3) from the dividend to 337 and continue with: 3373 / 354

Step 7:
The number 354 fits into 3373 9 times, leaving a remainder of 187.
The number 9 becomes the next digit in our result. 
Result so far: 15289.0
Deduct 3186 from 3373 and we're left with 187.
Bring next digit (6) of the dividend behind the 187 and repeat the process: 1876 / 354

Advancing to step 8:
354 can be fit into 1876 5 times, resulting in a remainder of 106.
The next digit of our result is 5. 
Result so far: 152895.0
Deduct 1770 from 1876 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 9:
354 goes into 1060 2 times with a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 152895.2
Subtracting 708 from 1060 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 10:
When dividing 3520 by 354, we get 9 with a remainder of 334.
Use 9 as the next digit of our solution. 
Result so far: 152895.29
Subtracting 3186 from 3520 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 11:
The number 354 fits into 3340 9 times, leaving a remainder of 154.
The number 9 becomes the next digit in our result. 
Result so far: 152895.299
Subtracting 3186 from 3340 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

In conclusion, the division gives 152895.299 with a balance of 0.0154.
