We divide 642363 by 19
We want to figure out the number of times 642363 can be divided by 19.

Advancing to step 1:
19 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 19

Going ahead to step 2:
If we divide 64 by 19, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 57 from 64 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 19

Let's proceed to step 3:
72 divided by 19 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 57 from 72, we get 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 19

Advancing to step 4:
The number 19 fits into 153 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 338.0
The remainder is 1 after subtracting 152 from 153.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 19

Going ahead to step 5:
16 divided by 19 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 3380.0
Subtract 0 from 16 to get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 19

Going ahead to step 6:
The number 19 fits into 163 8 times, leaving a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 33808.0
The remainder is 11 after subtracting 152 from 163.
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 7:
19 goes into 110 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 33808.5
The remainder is 15 after subtracting 95 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
When dividing 150 by 19, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 33808.57
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.

Advancing to step 9:
The number 19 fits into 170 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 33808.578
If we subtract 152 from 170, we 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.

Advancing to step 10:
When dividing 180 by 19, we get 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 33808.5789
Subtract 171 from 180 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
90 divided by 19 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 33808.57894
If we subtract 76 from 90, we get 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 12:
If we divide 140 by 19, we get 7 and a remainder of 7.
The next digit of our result is 7. 
Result so far: 33808.578947
Subtract 133 from 140 to 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.

Let's proceed to step 13:
The number 19 fits into 70 3 times, leaving a remainder of 13.
The next digit of our result is 3. 
Result so far: 33808.5789473
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.

Moving on to step 14:
The number 19 fits into 130 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 33808.57894736
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 33808.57894736, and the remainder is 1.6e-08.
