We look at the division of 18431731 by 404 
We want to divide 18431731 by 404.

On to step 1:
404 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 404

Advancing to step 2:
18 divided by 404 is 0 with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 404

Going ahead to step 3:
404 can be fit into 184 0 times, resulting in a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 184, we end up with 184.
Grab the next digit (3) from the dividend, add it to 184, then carry on: 1843 / 404

On to step 4:
When dividing 1843 by 404, we get 4 with a remainder of 227.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 1616 from 1843 and we're left with 227.
Fetch the next digit (1) from the dividend, attach it to 227 and continue: 2271 / 404

Let's proceed to step 5:
404 goes into 2271 5 times with a remainder of 251.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 251 after subtracting 2020 from 2271.
Fetch the next digit (7) from the dividend, attach it to 251 and continue: 2517 / 404

Going ahead to step 6:
The number 404 fits into 2517 6 times, leaving a remainder of 93.
The next digit of our result is 6. 
Result so far: 456.0
The remainder is 93 after subtracting 2424 from 2517.
Include the next digit (3) from the dividend after 93, then repeat: 933 / 404

Step 7:
404 can be fit into 933 2 times, resulting in a remainder of 125.
The number 2 becomes the next digit in our result. 
Result so far: 4562.0
Deduct 808 from 933 and we're left with 125.
Include the next digit (1) from the dividend after 125, then repeat: 1251 / 404

Moving on to step 8:
The number 404 fits into 1251 3 times, leaving a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 45623.0
Subtracting 1212 from 1251 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
The number 404 fits into 390 0 times, leaving a remainder of 390.
Put 0 as the next digit of the answer. 
Result so far: 45623.0
Subtract 0 from 390 to get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 10:
If we divide 3900 by 404, we get 9 and a remainder of 264.
The next digit of our result is 9. 
Result so far: 45623.09
The remainder is 264 after subtracting 3636 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 11:
When dividing 2640 by 404, we get 6 with a remainder of 216.
Write down 6 as next digit of the result. 
Result so far: 45623.096
If we take 2424 away from 2640, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 12:
404 can be fit into 2160 5 times, resulting in a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 45623.0965
Subtract 2020 from 2160 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 13:
When dividing 1400 by 404, we get 3 with a remainder of 188.
Put 3 as the next digit of the answer. 
Result so far: 45623.09653
The remainder is 188 after subtracting 1212 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

On to step 14:
404 goes into 1880 4 times with a remainder of 264.
Put 4 as the next digit of the answer. 
Result so far: 45623.096534
If we subtract 1616 from 1880, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 15:
404 goes into 2640 6 times with a remainder of 216.
The number 6 becomes the next digit in our result. 
Result so far: 45623.0965346
Subtract 2424 from 2640 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Advancing to step 16:
404 can be fit into 2160 5 times, resulting in a remainder of 140.
The next digit of our result is 5. 
Result so far: 45623.09653465
Subtract 2020 from 2160 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final outcome is 45623.09653465, with a leftover of 1.4e-07.
