339421 divided by 19 
We want to figure out the number of times 339421 can be divided by 19.

Let's proceed to step 1:
19 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
The remainder is 3 after subtracting 0 from 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 19

On to step 2:
If we divide 33 by 19, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 19 from 33 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 19

Let's proceed to step 3:
The number 19 fits into 149 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 133 away from 149, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 19

On to step 4:
19 goes into 164 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 178.0
If we subtract 152 from 164, we get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 19

Step 5:
19 can be fit into 122 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1786.0
Deduct 114 from 122 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 19

Advancing to step 6:
19 goes into 81 4 times with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 17864.0
The remainder is 5 after subtracting 76 from 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 19 fits into 50 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 17864.2
The remainder is 12 after subtracting 38 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
The number 19 fits into 120 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 17864.26
The remainder is 6 after subtracting 114 from 120.
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 9:
60 divided by 19 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 17864.263
If we take 57 away from 60, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
If we divide 30 by 19, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 17864.2631
Deduct 19 from 30 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 11:
The number 19 fits into 110 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 17864.26315
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
150 divided by 19 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 17864.263157
Deduct 133 from 150 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
If we divide 170 by 19, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 17864.2631578
If we take 152 away from 170, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
When dividing 180 by 19, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 17864.26315789
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 17864.26315789 with a remaining 9e-09.
