391764 divided by 42 
We want to divide 391764 by 42.

Moving on to step 1:
3 divided by 42 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 42

Step 2:
The number 42 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 42

On to step 3:
42 goes into 391 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 378 from 391 leaves us with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 42

Advancing to step 4:
42 can be fit into 137 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 93.0
Subtract 126 from 137 to get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 42

Step 5:
When dividing 116 by 42, we get 2 with a remainder of 32.
The next digit of our result is 2. 
Result so far: 932.0
Subtract 84 from 116 to get 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 42

Let's proceed to step 6:
324 divided by 42 is 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 9327.0
Deduct 294 from 324 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
When dividing 300 by 42, we get 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 9327.7
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 9327.71
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
42 goes into 180 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 9327.714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
120 divided by 42 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 9327.7142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 9327.71428
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
When dividing 240 by 42, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9327.714285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
If we divide 300 by 42, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 9327.7142857
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
42 can be fit into 60 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 9327.71428571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 9327.71428571, with a leftover of 1.8e-08.
