Let's divide 439651 by 19
We want to divide 439651 by 19.

Step 1:
When dividing 4 by 19, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 19

Advancing to step 2:
19 can be fit into 43 2 times, resulting in a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 5 after subtracting 38 from 43.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 19

Let's proceed to step 3:
59 divided by 19 is 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 57 away from 59, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 19

Going ahead to step 4:
19 goes into 26 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 231.0
The remainder is 7 after subtracting 19 from 26.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 19

Going ahead to step 5:
75 divided by 19 is 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 2313.0
If we subtract 57 from 75, we get 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 19

Moving on to step 6:
19 can be fit into 181 9 times, resulting in a remainder of 10.
The next digit of our result is 9. 
Result so far: 23139.0
Subtract 171 from 181 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
19 goes into 100 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 23139.5
Subtract 95 from 100 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 23139.52
If we subtract 38 from 50, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 19, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 23139.526
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
60 divided by 19 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 23139.5263
The remainder is 3 after subtracting 57 from 60.
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 11:
The number 19 fits into 30 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 23139.52631
If we take 19 away from 30, we end up 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.

On to step 12:
19 can be fit into 110 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 23139.526315
If we subtract 95 from 110, we 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.

Advancing to step 13:
If we divide 150 by 19, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 23139.5263157
If we subtract 133 from 150, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
When dividing 170 by 19, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 23139.52631578
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 23139.52631578, with a leftover of 1.8e-08.
