We're dividing 393370 by 42 
Our goal is to divide 393370 by 42.

Advancing to step 1:
If we divide 3 by 42, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 42

Step 2:
42 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 42

Advancing to step 3:
42 goes into 393 9 times with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 378 from 393, we get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 42

Let's proceed to step 4:
42 goes into 153 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 93.0
If we subtract 126 from 153, we get 27.
Take the next digit (7) from the dividend and append it to 27, then repeat: 277 / 42

On to step 5:
When dividing 277 by 42, we get 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 936.0
Deduct 252 from 277 and we're left with 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 42

Going ahead to step 6:
The number 42 fits into 250 5 times, leaving a remainder of 40.
The next digit of our result is 5. 
Result so far: 9365.0
If we subtract 210 from 250, we 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.

On to step 7:
42 can be fit into 400 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 9365.9
Subtract 378 from 400 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
When dividing 220 by 42, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9365.95
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 9365.952
If we take 84 away from 100, we end up 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.

On to step 10:
160 divided by 42 is 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 9365.9523
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 9365.95238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
42 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9365.95238
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.

Step 13:
When dividing 400 by 42, we get 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9365.9523809
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.

Advancing to step 14:
If we divide 220 by 42, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 9365.95238095
The remainder is 10 after subtracting 210 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 9365.95238095 and a remainder of 1e-08.
