We're dividing 38473578 by 393 
The aim is to understand the frequency of 393 in 38473578.

On to step 1:
3 divided by 393 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 393

On to step 2:
38 divided by 393 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 393

Moving on to step 3:
When dividing 384 by 393, we get 0 with a remainder of 384.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 384, we get 384.
Append the next digit (7) from the dividend to 384 and continue with: 3847 / 393

Let's proceed to step 4:
393 goes into 3847 9 times with a remainder of 310.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 3537 from 3847 and we're left with 310.
Bring next digit (3) of the dividend behind the 310 and repeat the process: 3103 / 393

Step 5:
393 goes into 3103 7 times with a remainder of 352.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we take 2751 away from 3103, we end up with 352.
Bring next digit (5) of the dividend behind the 352 and repeat the process: 3525 / 393

Step 6:
If we divide 3525 by 393, we get 8 and a remainder of 381.
The number 8 becomes the next digit in our result. 
Result so far: 978.0
Subtracting 3144 from 3525 leaves us with 381.
Fetch the next digit (7) from the dividend, attach it to 381 and continue: 3817 / 393

Moving on to step 7:
393 goes into 3817 9 times with a remainder of 280.
Record the quotient 9 as the next digit in the result. 
Result so far: 9789.0
Subtracting 3537 from 3817 leaves us with 280.
Bring next digit (8) of the dividend behind the 280 and repeat the process: 2808 / 393

Step 8:
393 goes into 2808 7 times with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 97897.0
If we take 2751 away from 2808, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 9:
570 divided by 393 is 1 with a remainder of 177.
Record the quotient 1 as the next digit in the result. 
Result so far: 97897.1
If we take 393 away from 570, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Moving on to step 10:
The number 393 fits into 1770 4 times, leaving a remainder of 198.
Put 4 as the next digit of the answer. 
Result so far: 97897.14
If we take 1572 away from 1770, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 11:
If we divide 1980 by 393, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 97897.145
The remainder is 15 after subtracting 1965 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
If we divide 150 by 393, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 97897.145
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
393 goes into 1500 3 times with a remainder of 321.
The number 3 becomes the next digit in our result. 
Result so far: 97897.14503
Subtracting 1179 from 1500 leaves us with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 14:
393 can be fit into 3210 8 times, resulting in a remainder of 66.
The next digit of our result is 8. 
Result so far: 97897.145038
Subtracting 3144 from 3210 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 15:
660 divided by 393 is 1 with a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 97897.1450381
The remainder is 267 after subtracting 393 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Step 16:
393 can be fit into 2670 6 times, resulting in a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 97897.14503816
Subtracting 2358 from 2670 leaves us with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

In conclusion, the division gives 97897.14503816 with a balance of 3.12e-07.
