We're dividing 38948787 by 728 
The aim is to understand the frequency of 728 in 38948787.

Advancing to step 1:
When dividing 3 by 728, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 728

Step 2:
728 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 728

Step 3:
728 can be fit into 389 0 times, resulting in a remainder of 389.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 389 and we're left with 389.
Take the next digit (4) from the dividend and append it to 389, then repeat: 3894 / 728

Let's proceed to step 4:
If we divide 3894 by 728, we get 5 and a remainder of 254.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3640 from 3894 and we're left with 254.
Grab the next digit (8) from the dividend, add it to 254, then carry on: 2548 / 728

Moving on to step 5:
If we divide 2548 by 728, we get 3 and a remainder of 364.
Put 3 as the next digit of the answer. 
Result so far: 53.0
The remainder is 364 after subtracting 2184 from 2548.
Take the next digit (7) from the dividend and append it to 364, then repeat: 3647 / 728

Let's proceed to step 6:
3647 divided by 728 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 535.0
If we take 3640 away from 3647, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 728

Going ahead to step 7:
728 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 5350.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (7) from the dividend, attach it to 78 and continue: 787 / 728

Step 8:
728 can be fit into 787 1 times, resulting in a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 53501.0
If we take 728 away from 787, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 9:
If we divide 590 by 728, we get 0 and a remainder of 590.
Use 0 as the next digit of our solution. 
Result so far: 53501.0
Deduct 0 from 590 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 10:
If we divide 5900 by 728, we get 8 and a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 53501.08
Deduct 5824 from 5900 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
The number 728 fits into 760 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 53501.081
If we take 728 away from 760, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
728 goes into 320 0 times with a remainder of 320.
Use 0 as the next digit of our solution. 
Result so far: 53501.081
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 13:
When dividing 3200 by 728, we get 4 with a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 53501.08104
If we take 2912 away from 3200, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 14:
If we divide 2880 by 728, we get 3 and a remainder of 696.
Write down 3 as next digit of the result. 
Result so far: 53501.081043
Subtracting 2184 from 2880 leaves us with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Moving on to step 15:
The number 728 fits into 6960 9 times, leaving a remainder of 408.
Write down 9 as next digit of the result. 
Result so far: 53501.0810439
If we subtract 6552 from 6960, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 16:
When dividing 4080 by 728, we get 5 with a remainder of 440.
Use 5 as the next digit of our solution. 
Result so far: 53501.08104395
If we subtract 3640 from 4080, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

In conclusion, the division gives 53501.08104395 with a balance of 4.4e-07.
