12366011 ÷ 388 
The aim is to understand the frequency of 388 in 12366011.

On to step 1:
388 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 388

Advancing to step 2:
If we divide 12 by 388, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 388

On to step 3:
388 goes into 123 0 times with a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 123 after subtracting 0 from 123.
Include the next digit (6) from the dividend after 123, then repeat: 1236 / 388

Moving on to step 4:
When dividing 1236 by 388, we get 3 with a remainder of 72.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 1164 from 1236 and we're left with 72.
Include the next digit (6) from the dividend after 72, then repeat: 726 / 388

Step 5:
If we divide 726 by 388, we get 1 and a remainder of 338.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 388 away from 726, we end up with 338.
Bring next digit (0) of the dividend behind the 338 and repeat the process: 3380 / 388

Going ahead to step 6:
If we divide 3380 by 388, we get 8 and a remainder of 276.
Record the quotient 8 as the next digit in the result. 
Result so far: 318.0
If we subtract 3104 from 3380, we get 276.
Include the next digit (1) from the dividend after 276, then repeat: 2761 / 388

Moving on to step 7:
The number 388 fits into 2761 7 times, leaving a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 3187.0
Deduct 2716 from 2761 and we're left with 45.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 388

On to step 8:
If we divide 451 by 388, we get 1 and a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 31871.0
Deduct 388 from 451 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
630 divided by 388 is 1 with a remainder of 242.
The number 1 becomes the next digit in our result. 
Result so far: 31871.1
Deduct 388 from 630 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 10:
When dividing 2420 by 388, we get 6 with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 31871.16
Subtracting 2328 from 2420 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 11:
920 divided by 388 is 2 with a remainder of 144.
The next digit of our result is 2. 
Result so far: 31871.162
If we subtract 776 from 920, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 12:
1440 divided by 388 is 3 with a remainder of 276.
Record the quotient 3 as the next digit in the result. 
Result so far: 31871.1623
The remainder is 276 after subtracting 1164 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 13:
The number 388 fits into 2760 7 times, leaving a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 31871.16237
If we take 2716 away from 2760, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
When dividing 440 by 388, we get 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 31871.162371
Subtracting 388 from 440 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 15:
388 goes into 520 1 times with a remainder of 132.
Write down 1 as next digit of the result. 
Result so far: 31871.1623711
Deduct 388 from 520 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

In conclusion, the division gives 31871.1623711 with a balance of 1.32e-06.
