The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 704

Advancing to step 3:
When dividing 198 by 704, we get 0 with a remainder of 198.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 198 after subtracting 0 from 198.
Take the next digit (9) from the dividend and append it to 198, then repeat: 1989 / 704

On to step 4:
704 goes into 1989 2 times with a remainder of 581.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 581 after subtracting 1408 from 1989.
Fetch the next digit (9) from the dividend, attach it to 581 and continue: 5819 / 704

Advancing to step 5:
When dividing 5819 by 704, we get 8 with a remainder of 187.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 5632 from 5819 and we're left with 187.
Fetch the next digit (0) from the dividend, attach it to 187 and continue: 1870 / 704

Let's proceed to step 6:
704 can be fit into 1870 2 times, resulting in a remainder of 462.
Write down 2 as next digit of the result. 
Result so far: 282.0
Subtract 1408 from 1870 to get 462.
Append the next digit (9) from the dividend to 462 and continue with: 4629 / 704

Advancing to step 7:
4629 divided by 704 is 6 with a remainder of 405.
Write down 6 as next digit of the result. 
Result so far: 2826.0
Subtracting 4224 from 4629 leaves us with 405.
Include the next digit (0) from the dividend after 405, then repeat: 4050 / 704

Moving on to step 8:
When dividing 4050 by 704, we get 5 with a remainder of 530.
Write down 5 as next digit of the result. 
Result so far: 28265.0
If we subtract 3520 from 4050, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 9:
The number 704 fits into 5300 7 times, leaving a remainder of 372.
Put 7 as the next digit of the answer. 
Result so far: 28265.7
Subtracting 4928 from 5300 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 10:
704 goes into 3720 5 times with a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 28265.75
Subtracting 3520 from 3720 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
If we divide 2000 by 704, we get 2 and a remainder of 592.
The next digit of our result is 2. 
Result so far: 28265.752
If we take 1408 away from 2000, we end up with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 12:
If we divide 5920 by 704, we get 8 and a remainder of 288.
Use 8 as the next digit of our solution. 
Result so far: 28265.7528
Deduct 5632 from 5920 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Going ahead to step 13:
If we divide 2880 by 704, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 28265.75284
Deduct 2816 from 2880 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
640 divided by 704 is 0 with a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 28265.75284
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 15:
The number 704 fits into 6400 9 times, leaving a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 28265.7528409
The remainder is 64 after subtracting 6336 from 6400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 16:
704 can be fit into 640 0 times, resulting in a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 28265.7528409
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 28265.7528409 with a remaining 6.4e-07.
