Let's divide 38966334 by 321
Let's see how many times 321 fits into 38966334.

Let's proceed to step 1:
321 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 321

Step 2:
When dividing 38 by 321, we get 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 321

Let's proceed to step 3:
321 goes into 389 1 times with a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 321 away from 389, we end up with 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 321

Going ahead to step 4:
686 divided by 321 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 642 from 686 and we're left with 44.
Append the next digit (6) from the dividend to 44 and continue with: 446 / 321

Let's proceed to step 5:
321 can be fit into 446 1 times, resulting in a remainder of 125.
Use 1 as the next digit of our solution. 
Result so far: 121.0
If we subtract 321 from 446, we get 125.
Include the next digit (3) from the dividend after 125, then repeat: 1253 / 321

Advancing to step 6:
321 can be fit into 1253 3 times, resulting in a remainder of 290.
Record the quotient 3 as the next digit in the result. 
Result so far: 1213.0
Deduct 963 from 1253 and we're left with 290.
Take the next digit (3) from the dividend and append it to 290, then repeat: 2903 / 321

Advancing to step 7:
The number 321 fits into 2903 9 times, leaving a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 12139.0
Subtract 2889 from 2903 to get 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 321

Going ahead to step 8:
If we divide 144 by 321, we get 0 and a remainder of 144.
Put 0 as the next digit of the answer. 
Result so far: 121390.0
If we subtract 0 from 144, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 9:
321 can be fit into 1440 4 times, resulting in a remainder of 156.
The number 4 becomes the next digit in our result. 
Result so far: 121390.4
Subtract 1284 from 1440 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 10:
321 can be fit into 1560 4 times, resulting in a remainder of 276.
Put 4 as the next digit of the answer. 
Result so far: 121390.44
Subtracting 1284 from 1560 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final outcome is 121390.44, with a leftover of 0.276.
