642278 divided by 19 
We want to figure out the number of times 642278 can be divided by 19.

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
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 19

Let's proceed to step 2:
64 divided by 19 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 57 from 64 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 19

Advancing to step 3:
When dividing 72 by 19, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 57 away from 72, we end up with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 19

Step 4:
152 divided by 19 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 338.0
Subtracting 152 from 152 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 19

Advancing to step 5:
If we divide 7 by 19, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 3380.0
Subtract 0 from 7 to get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 19

Step 6:
When dividing 78 by 19, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 33804.0
If we take 76 away from 78, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
19 goes into 20 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 33804.1
Deduct 19 from 20 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
19 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 33804.1
If we subtract 0 from 10, we 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 9:
19 can be fit into 100 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33804.105
Deduct 95 from 100 and we're left with 5.
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 10:
19 goes into 50 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 33804.1052
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.

On to step 11:
19 goes into 120 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 33804.10526
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 12:
60 divided by 19 is 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 33804.105263
Subtracting 57 from 60 leaves us 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 13:
19 goes into 30 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 33804.1052631
If we subtract 19 from 30, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
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: 33804.10526315
Deduct 95 from 110 and we're left 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.

After the division, we end up with 33804.10526315 and a remainder of 1.5e-08.
