The number 404 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 404

Advancing to step 2:
404 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (5) from the dividend, add it to 42, then carry on: 425 / 404

On to step 3:
The number 404 fits into 425 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 404 away from 425, we end up with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 404

Going ahead to step 4:
If we divide 219 by 404, we get 0 and a remainder of 219.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 219 after subtracting 0 from 219.
Fetch the next digit (9) from the dividend, attach it to 219 and continue: 2199 / 404

Going ahead to step 5:
2199 divided by 404 is 5 with a remainder of 179.
The next digit of our result is 5. 
Result so far: 105.0
Subtracting 2020 from 2199 leaves us with 179.
Append the next digit (7) from the dividend to 179 and continue with: 1797 / 404

Going ahead to step 6:
1797 divided by 404 is 4 with a remainder of 181.
Record the quotient 4 as the next digit in the result. 
Result so far: 1054.0
Subtracting 1616 from 1797 leaves us with 181.
Take the next digit (0) from the dividend and append it to 181, then repeat: 1810 / 404

Step 7:
When dividing 1810 by 404, we get 4 with a remainder of 194.
Record the quotient 4 as the next digit in the result. 
Result so far: 10544.0
If we take 1616 away from 1810, we end up with 194.
Grab the next digit (8) from the dividend, add it to 194, then carry on: 1948 / 404

On to step 8:
When dividing 1948 by 404, we get 4 with a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 105444.0
Deduct 1616 from 1948 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Advancing to step 9:
If we divide 3320 by 404, we get 8 and a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 105444.8
Subtract 3232 from 3320 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 10:
The number 404 fits into 880 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 105444.82
Subtracting 808 from 880 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 11:
404 can be fit into 720 1 times, resulting in a remainder of 316.
The next digit of our result is 1. 
Result so far: 105444.821
If we take 404 away from 720, we end up with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Moving on to step 12:
3160 divided by 404 is 7 with a remainder of 332.
The next digit of our result is 7. 
Result so far: 105444.8217
If we take 2828 away from 3160, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 13:
404 goes into 3320 8 times with a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 105444.82178
The remainder is 88 after subtracting 3232 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
If we divide 880 by 404, we get 2 and a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 105444.821782
Subtracting 808 from 880 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 15:
The number 404 fits into 720 1 times, leaving a remainder of 316.
Put 1 as the next digit of the answer. 
Result so far: 105444.8217821
Deduct 404 from 720 and we're left with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 16:
404 goes into 3160 7 times with a remainder of 332.
Use 7 as the next digit of our solution. 
Result so far: 105444.82178217
If we take 2828 away from 3160, we end up with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

After the division, we end up with 105444.82178217 and a remainder of 3.32e-07.
