We divide 103990 by 19
Let's see how many times 19 fits into 103990.

Moving on to step 1:
If we divide 1 by 19, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 19

Step 2:
The number 19 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 19

Advancing to step 3:
19 goes into 103 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 95 from 103 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 19

Moving on to step 4:
19 goes into 89 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 54.0
The remainder is 13 after subtracting 76 from 89.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 19

Advancing to step 5:
19 goes into 139 7 times with a remainder of 6.
The next digit of our result is 7. 
Result so far: 547.0
Deduct 133 from 139 and we're left with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 19

Advancing to step 6:
When dividing 60 by 19, we get 3 with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 5473.0
Subtract 57 from 60 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 19, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 5473.1
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.

Step 8:
110 divided by 19 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 5473.15
Subtract 95 from 110 to 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.

Step 9:
When dividing 150 by 19, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 5473.157
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.

Step 10:
The number 19 fits into 170 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 5473.1578
Subtracting 152 from 170 leaves us with 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 11:
When dividing 180 by 19, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 5473.15789
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.

On to step 12:
19 goes into 90 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 5473.157894
Subtracting 76 from 90 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
140 divided by 19 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 5473.1578947
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.

Step 14:
If we divide 70 by 19, we get 3 and a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 5473.15789473
If we subtract 57 from 70, we 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.

After the division, we end up with 5473.15789473 and a remainder of 1.3e-08.
