388204 ÷ 42 
We're looking to find how many times 42 goes into 388204.

On to step 1:
42 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 42

Advancing to step 2:
If we divide 38 by 42, we get 0 and a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 42

Moving on to step 3:
388 divided by 42 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 378 from 388 and we're left with 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 42

Going ahead to step 4:
The number 42 fits into 102 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 92.0
If we take 84 away from 102, we end up with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 42

Going ahead to step 5:
180 divided by 42 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 924.0
Deduct 168 from 180 and we're left with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 42

Moving on to step 6:
124 divided by 42 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 9242.0
If we take 84 away from 124, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 9242.9
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
42 goes into 220 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9242.95
Subtracting 210 from 220 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
When dividing 100 by 42, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 9242.952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
160 divided by 42 is 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 9242.9523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
340 divided by 42 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 9242.95238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
42 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9242.95238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 13:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 9242.9523809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
42 goes into 220 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 9242.95238095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 9242.95238095 with a remainder of 1e-08.
