6 divided by 404 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 404

Moving on to step 2:
69 divided by 404 is 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Fetch the next digit (1) from the dividend, attach it to 69 and continue: 691 / 404

Going ahead to step 3:
691 divided by 404 is 1 with a remainder of 287.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 404 from 691 leaves us with 287.

Let's proceed to step 4:
2876 divided by 404 is 7 with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 2828 from 2876 and we're left with 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 404

Moving on to step 5:
488 divided by 404 is 1 with a remainder of 84.
The next digit of our result is 1. 
Result so far: 171.0
If we subtract 404 from 488, we get 84.
Fetch the next digit (8) from the dividend, attach it to 84 and continue: 848 / 404

Let's proceed to step 6:
When dividing 848 by 404, we get 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1712.0
The remainder is 40 after subtracting 808 from 848.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 404

Going ahead to step 7:
When dividing 409 by 404, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 17121.0
Subtracting 404 from 409 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 404

Moving on to step 8:
When dividing 52 by 404, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 171210.0
If we take 0 away from 52, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
404 can be fit into 520 1 times, resulting in a remainder of 116.
Put 1 as the next digit of the answer. 
Result so far: 171210.1
The remainder is 116 after subtracting 404 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
The number 404 fits into 1160 2 times, leaving a remainder of 352.
The next digit of our result is 2. 
Result so far: 171210.12
Deduct 808 from 1160 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 11:
If we divide 3520 by 404, we get 8 and a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 171210.128
Deduct 3232 from 3520 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 12:
404 goes into 2880 7 times with a remainder of 52.
The number 7 becomes the next digit in our result. 
Result so far: 171210.1287
If we subtract 2828 from 2880, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
If we divide 520 by 404, we get 1 and a remainder of 116.
The next digit of our result is 1. 
Result so far: 171210.12871
If we subtract 404 from 520, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Advancing to step 14:
404 goes into 1160 2 times with a remainder of 352.
Use 2 as the next digit of our solution. 
Result so far: 171210.128712
Deduct 808 from 1160 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 15:
404 can be fit into 3520 8 times, resulting in a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 171210.1287128
If we take 3232 away from 3520, we end up 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.

Let's proceed to step 16:
2880 divided by 404 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 171210.12871287
If we subtract 2828 from 2880, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 171210.12871287 with a remainder of 5.2e-08.
