We're dividing 63788139 by 19 
We want to figure out the number of times 63788139 can be divided by 19.

On to step 1:
When dividing 6 by 19, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 19

Step 2:
If we divide 63 by 19, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 57 from 63 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 19

Going ahead to step 3:
The number 19 fits into 67 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtracting 57 from 67 leaves us with 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 19

Going ahead to step 4:
When dividing 108 by 19, we get 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 335.0
If we subtract 95 from 108, we get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 19

Advancing to step 5:
19 can be fit into 138 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 3357.0
Deduct 133 from 138 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 19

Advancing to step 6:
51 divided by 19 is 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 33572.0
Subtract 38 from 51 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 19

Advancing to step 7:
The number 19 fits into 133 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 335727.0
If we take 133 away from 133, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 19

Step 8:
19 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 3357270.0
Subtract 0 from 9 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.

Let's proceed to step 9:
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: 3357270.4
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.

Advancing to step 10:
19 goes into 140 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 3357270.47
Deduct 133 from 140 and we're left with 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 11:
The number 19 fits into 70 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3357270.473
Deduct 57 from 70 and we're left 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 12:
19 can be fit into 130 6 times, resulting in a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 3357270.4736
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.

Step 13:
19 can be fit into 160 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 3357270.47368
Subtracting 152 from 160 leaves us 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.

Going ahead to step 14:
If we divide 80 by 19, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 3357270.473684
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 15:
The number 19 fits into 40 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 3357270.4736842
Subtracting 38 from 40 leaves us 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 16:
When dividing 20 by 19, we get 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 3357270.47368421
If we subtract 19 from 20, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 3357270.47368421 with a remainder of 1e-09.
