Let's divide 119421 by 3
We're looking to find how many times 3 goes into 119421.

Advancing to step 1:
3 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 3

Step 2:
11 divided by 3 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 9 away from 11, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Going ahead to step 3:
If we divide 29 by 3, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 39.0
If we subtract 27 from 29, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

Advancing to step 4:
24 divided by 3 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 398.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

Going ahead to step 5:
3 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 3980.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Moving on to step 6:
3 can be fit into 21 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 39807.0
Subtracting 21 from 21 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
3 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39807.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 3 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39807.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 39807.0 with a remaining 0.0.
