Let's divide 12023643 by 388
We want to figure out the number of times 12023643 can be divided by 388.

Step 1:
When dividing 1 by 388, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 388

Advancing to step 2:
388 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 388

Let's proceed to step 3:
The number 388 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 120 leaves us with 120.
Bring next digit (2) of the dividend behind the 120 and repeat the process: 1202 / 388

Going ahead to step 4:
When dividing 1202 by 388, we get 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 1164 from 1202 leaves us with 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 388

Advancing to step 5:
The number 388 fits into 383 0 times, leaving a remainder of 383.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 383, we get 383.
Fetch the next digit (6) from the dividend, attach it to 383 and continue: 3836 / 388

Going ahead to step 6:
If we divide 3836 by 388, we get 9 and a remainder of 344.
The next digit of our result is 9. 
Result so far: 309.0
The remainder is 344 after subtracting 3492 from 3836.
Fetch the next digit (4) from the dividend, attach it to 344 and continue: 3444 / 388

Step 7:
The number 388 fits into 3444 8 times, leaving a remainder of 340.
The next digit of our result is 8. 
Result so far: 3098.0
If we subtract 3104 from 3444, we get 340.
Include the next digit (3) from the dividend after 340, then repeat: 3403 / 388

On to step 8:
388 goes into 3403 8 times with a remainder of 299.
Record the quotient 8 as the next digit in the result. 
Result so far: 30988.0
If we subtract 3104 from 3403, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 9:
388 goes into 2990 7 times with a remainder of 274.
Put 7 as the next digit of the answer. 
Result so far: 30988.7
Subtract 2716 from 2990 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 10:
2740 divided by 388 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 30988.77
Deduct 2716 from 2740 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 30988.77, with a leftover of 0.024.
