Append the next digit (2) from the dividend to 4 and continue with: 42 / 388

On to step 2:
42 divided by 388 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 388

Moving on to step 3:
If we divide 425 by 388, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 388 from 425 leaves us with 37.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 388

Step 4:
If we divide 377 by 388, we get 0 and a remainder of 377.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 377 after subtracting 0 from 377.
Take the next digit (9) from the dividend and append it to 377, then repeat: 3779 / 388

Going ahead to step 5:
3779 divided by 388 is 9 with a remainder of 287.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Deduct 3492 from 3779 and we're left with 287.
Include the next digit (0) from the dividend after 287, then repeat: 2870 / 388

Going ahead to step 6:
2870 divided by 388 is 7 with a remainder of 154.
Write down 7 as next digit of the result. 
Result so far: 1097.0
If we subtract 2716 from 2870, we get 154.
Include the next digit (1) from the dividend after 154, then repeat: 1541 / 388

On to step 7:
The number 388 fits into 1541 3 times, leaving a remainder of 377.
Put 3 as the next digit of the answer. 
Result so far: 10973.0
If we take 1164 away from 1541, we end up with 377.
Append the next digit (4) from the dividend to 377 and continue with: 3774 / 388

Let's proceed to step 8:
The number 388 fits into 3774 9 times, leaving a remainder of 282.
The number 9 becomes the next digit in our result. 
Result so far: 109739.0
Deduct 3492 from 3774 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 9:
388 goes into 2820 7 times with a remainder of 104.
The next digit of our result is 7. 
Result so far: 109739.7
Subtract 2716 from 2820 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
When dividing 1040 by 388, we get 2 with a remainder of 264.
The number 2 becomes the next digit in our result. 
Result so far: 109739.72
The remainder is 264 after subtracting 776 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 11:
If we divide 2640 by 388, we get 6 and a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 109739.726
Subtract 2328 from 2640 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 12:
3120 divided by 388 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 109739.7268
Deduct 3104 from 3120 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
388 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 109739.7268
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 14:
388 goes into 1600 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 109739.726804
Deduct 1552 from 1600 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 15:
The number 388 fits into 480 1 times, leaving a remainder of 92.
Use 1 as the next digit of our solution. 
Result so far: 109739.7268041
Deduct 388 from 480 and we're left 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.

On to step 16:
The number 388 fits into 920 2 times, leaving a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 109739.72680412
Deduct 776 from 920 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 109739.72680412, with a leftover of 1.44e-07.
