We divide 99372759 by 388
The aim is to understand the frequency of 388 in 99372759.

Step 1:
If we divide 9 by 388, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 388

Going ahead to step 2:
If we divide 99 by 388, we get 0 and a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 388

On to step 3:
388 goes into 993 2 times with a remainder of 217.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 776 from 993 leaves us with 217.
Append the next digit (7) from the dividend to 217 and continue with: 2177 / 388

Moving on to step 4:
388 goes into 2177 5 times with a remainder of 237.
The next digit of our result is 5. 
Result so far: 25.0
Deduct 1940 from 2177 and we're left with 237.
Bring next digit (2) of the dividend behind the 237 and repeat the process: 2372 / 388

Let's proceed to step 5:
388 can be fit into 2372 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
Subtracting 2328 from 2372 leaves us with 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 388

Advancing to step 6:
447 divided by 388 is 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 2561.0
If we take 388 away from 447, we end up with 59.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 388

On to step 7:
If we divide 595 by 388, we get 1 and a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 25611.0
Subtracting 388 from 595 leaves us with 207.
Append the next digit (9) from the dividend to 207 and continue with: 2079 / 388

Advancing to step 8:
The number 388 fits into 2079 5 times, leaving a remainder of 139.
The next digit of our result is 5. 
Result so far: 256115.0
Deduct 1940 from 2079 and we're left with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 9:
If we divide 1390 by 388, we get 3 and a remainder of 226.
Record the quotient 3 as the next digit in the result. 
Result so far: 256115.3
If we subtract 1164 from 1390, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 10:
2260 divided by 388 is 5 with a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 256115.35
Subtract 1940 from 2260 to 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.

Let's proceed to step 11:
The number 388 fits into 3200 8 times, leaving a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 256115.358
Deduct 3104 from 3200 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
If we divide 960 by 388, we get 2 and a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 256115.3582
Subtract 776 from 960 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 13:
1840 divided by 388 is 4 with a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 256115.35824
Subtracting 1552 from 1840 leaves us 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.

Step 14:
If we divide 2880 by 388, we get 7 and a remainder of 164.
Write down 7 as next digit of the result. 
Result so far: 256115.358247
The remainder is 164 after subtracting 2716 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 15:
388 can be fit into 1640 4 times, resulting in a remainder of 88.
The next digit of our result is 4. 
Result so far: 256115.3582474
Subtracting 1552 from 1640 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 16:
If we divide 880 by 388, we get 2 and a remainder of 104.
The number 2 becomes the next digit in our result. 
Result so far: 256115.35824742
Deduct 776 from 880 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The final result is 256115.35824742 with a remainder of 1.04e-07.
