We look at the division of 149313 by 19 
Let's see how many times 19 fits into 149313.

Step 1:
If we divide 1 by 19, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 19

Going ahead to step 2:
If we divide 14 by 19, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 19

Advancing to step 3:
19 can be fit into 149 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 133 from 149 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 19

On to step 4:
163 divided by 19 is 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtract 152 from 163 to get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 19

On to step 5:
111 divided by 19 is 5 with a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 785.0
If we subtract 95 from 111, we get 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 19

Moving on to step 6:
The number 19 fits into 163 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 7858.0
Subtracting 152 from 163 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 7:
110 divided by 19 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 7858.5
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.

Let's proceed to step 8:
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: 7858.57
If we take 133 away from 150, we end up 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.

Let's proceed to step 9:
19 can be fit into 170 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 7858.578
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
19 goes into 180 9 times with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 7858.5789
The remainder is 9 after subtracting 171 from 180.
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 11:
90 divided by 19 is 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 7858.57894
The remainder is 14 after subtracting 76 from 90.
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 12:
When dividing 140 by 19, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7858.578947
If we subtract 133 from 140, we 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.

Going ahead to step 13:
19 goes into 70 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 7858.5789473
The remainder is 13 after subtracting 57 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
19 goes into 130 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 7858.57894736
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.

After the division, we end up with 7858.57894736 and a remainder of 1.6e-08.
