398920 ÷ 19 
Let's see how many times 19 fits into 398920.

Going ahead to step 1:
19 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 19

Going ahead to step 2:
The number 19 fits into 39 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 38 from 39 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 19

Going ahead to step 3:
The number 19 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 18 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 19

Let's proceed to step 4:
19 can be fit into 189 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 209.0
Subtracting 171 from 189 leaves us with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 19

Moving on to step 5:
The number 19 fits into 182 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 2099.0
Deduct 171 from 182 and we're left with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 19

On to step 6:
If we divide 110 by 19, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 20995.0
Subtract 95 from 110 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
If we divide 150 by 19, we get 7 and a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 20995.7
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.

Going ahead to step 8:
When dividing 170 by 19, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 20995.78
Deduct 152 from 170 and we're left 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.

Step 9:
If we divide 180 by 19, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 20995.789
If we take 171 away from 180, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
19 can be fit into 90 4 times, resulting in a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 20995.7894
Deduct 76 from 90 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
The number 19 fits into 140 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 20995.78947
If we subtract 133 from 140, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
70 divided by 19 is 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 20995.789473
Subtracting 57 from 70 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
19 can be fit into 130 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 20995.7894736
The remainder is 16 after subtracting 114 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
160 divided by 19 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 20995.78947368
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 20995.78947368 with a remainder of 8e-09.
