19 divided by 39 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 11240.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 39

On to step 7:
190 divided by 39 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 112404.0
If we take 156 away from 190, we end up with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 39

Moving on to step 8:
The number 39 fits into 349 8 times, leaving a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 1124048.0
Subtracting 312 from 349 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
The number 39 fits into 370 9 times, leaving a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 1124048.9
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 10:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 1124048.94
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
39 goes into 340 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 1124048.948
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 1124048.9487
Deduct 273 from 280 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.

Moving on to step 13:
39 can be fit into 70 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1124048.94871
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 14:
When dividing 310 by 39, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 1124048.948717
If we take 273 away from 310, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 15:
39 can be fit into 370 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 1124048.9487179
Subtract 351 from 370 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 16:
If we divide 190 by 39, we get 4 and a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 1124048.94871794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.
