3987305 divided by 19 
We're looking to find how many times 19 goes into 3987305.

Advancing to step 1:
19 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 19

Moving on to step 2:
The number 19 fits into 39 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 38 from 39 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 19

Advancing to step 3:
19 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 18, we get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 19

Let's proceed to step 4:
The number 19 fits into 187 9 times, leaving a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
Subtracting 171 from 187 leaves us with 16.
Append the next digit (3) from the dividend to 16 and continue with: 163 / 19

Step 5:
19 goes into 163 8 times with a remainder of 11.
The next digit of our result is 8. 
Result so far: 2098.0
If we subtract 152 from 163, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 19

Going ahead to step 6:
110 divided by 19 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 20985.0
If we subtract 95 from 110, we get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 19

Advancing to step 7:
The number 19 fits into 155 8 times, leaving a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 209858.0
Deduct 152 from 155 and we're left 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.

Step 8:
30 divided by 19 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 209858.1
Subtracting 19 from 30 leaves us 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.

Going ahead to step 9:
19 goes into 110 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 209858.15
Subtracting 95 from 110 leaves us 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.

On to step 10:
19 can be fit into 150 7 times, resulting in a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 209858.157
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.

On to step 11:
170 divided by 19 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 209858.1578
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.

On to step 12:
19 can be fit into 180 9 times, resulting in a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 209858.15789
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 13:
19 can be fit into 90 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 209858.157894
Subtract 76 from 90 to 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.

Going ahead to step 14:
When dividing 140 by 19, we get 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 209858.1578947
The remainder is 7 after subtracting 133 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 15:
19 can be fit into 70 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 209858.15789473
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 209858.15789473 with a balance of 1.3e-08.
