We're dividing 38136845 by 648 
The aim is to understand the frequency of 648 in 38136845.

Going ahead to step 1:
The number 648 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 648

Advancing to step 2:
When dividing 38 by 648, we get 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 648

Let's proceed to step 3:
If we divide 381 by 648, we get 0 and a remainder of 381.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 381, we end up with 381.
Append the next digit (3) from the dividend to 381 and continue with: 3813 / 648

Moving on to step 4:
When dividing 3813 by 648, we get 5 with a remainder of 573.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 573 after subtracting 3240 from 3813.
Fetch the next digit (6) from the dividend, attach it to 573 and continue: 5736 / 648

Step 5:
If we divide 5736 by 648, we get 8 and a remainder of 552.
Use 8 as the next digit of our solution. 
Result so far: 58.0
The remainder is 552 after subtracting 5184 from 5736.
Grab the next digit (8) from the dividend, add it to 552, then carry on: 5528 / 648

Going ahead to step 6:
5528 divided by 648 is 8 with a remainder of 344.
The number 8 becomes the next digit in our result. 
Result so far: 588.0
If we take 5184 away from 5528, we end up with 344.
Fetch the next digit (4) from the dividend, attach it to 344 and continue: 3444 / 648

Step 7:
648 goes into 3444 5 times with a remainder of 204.
Use 5 as the next digit of our solution. 
Result so far: 5885.0
The remainder is 204 after subtracting 3240 from 3444.
Grab the next digit (5) from the dividend, add it to 204, then carry on: 2045 / 648

Let's proceed to step 8:
2045 divided by 648 is 3 with a remainder of 101.
The next digit of our result is 3. 
Result so far: 58853.0
Deduct 1944 from 2045 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 9:
648 goes into 1010 1 times with a remainder of 362.
The next digit of our result is 1. 
Result so far: 58853.1
If we take 648 away from 1010, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Advancing to step 10:
If we divide 3620 by 648, we get 5 and a remainder of 380.
The next digit of our result is 5. 
Result so far: 58853.15
If we subtract 3240 from 3620, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
When dividing 3800 by 648, we get 5 with a remainder of 560.
Put 5 as the next digit of the answer. 
Result so far: 58853.155
If we take 3240 away from 3800, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

In conclusion, the division gives 58853.155 with a balance of 0.056.
