3917438 ÷ 326 
Let's see how many times 326 fits into 3917438.

Step 1:
326 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 326

Step 2:
326 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 326

Let's proceed to step 3:
The number 326 fits into 391 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 326 away from 391, we end up with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 326

Moving on to step 4:
326 goes into 657 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 652 from 657 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 326

Moving on to step 5:
The number 326 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtract 0 from 54 to get 54.
Bring next digit (3) of the dividend behind the 54 and repeat the process: 543 / 326

Going ahead to step 6:
326 goes into 543 1 times with a remainder of 217.
Use 1 as the next digit of our solution. 
Result so far: 1201.0
The remainder is 217 after subtracting 326 from 543.
Include the next digit (8) from the dividend after 217, then repeat: 2178 / 326

Going ahead to step 7:
If we divide 2178 by 326, we get 6 and a remainder of 222.
The number 6 becomes the next digit in our result. 
Result so far: 12016.0
Deduct 1956 from 2178 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Advancing to step 8:
2220 divided by 326 is 6 with a remainder of 264.
Record the quotient 6 as the next digit in the result. 
Result so far: 12016.6
The remainder is 264 after subtracting 1956 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 9:
When dividing 2640 by 326, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 12016.68
Subtracting 2608 from 2640 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
If we divide 320 by 326, we get 0 and a remainder of 320.
Write down 0 as next digit of the result. 
Result so far: 12016.68
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 11:
The number 326 fits into 3200 9 times, leaving a remainder of 266.
The number 9 becomes the next digit in our result. 
Result so far: 12016.6809
If we subtract 2934 from 3200, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 12:
326 goes into 2660 8 times with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 12016.68098
The remainder is 52 after subtracting 2608 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
If we divide 520 by 326, we get 1 and a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 12016.680981
Subtracting 326 from 520 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 14:
1940 divided by 326 is 5 with a remainder of 310.
The next digit of our result is 5. 
Result so far: 12016.6809815
Subtract 1630 from 1940 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 15:
The number 326 fits into 3100 9 times, leaving a remainder of 166.
Put 9 as the next digit of the answer. 
Result so far: 12016.68098159
Deduct 2934 from 3100 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

The final result is 12016.68098159 with a remainder of 1.66e-07.
