6340588 ÷ 404 
We want to figure out the number of times 6340588 can be divided by 404.

On to step 1:
404 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 404

Step 2:
404 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Include the next digit (4) from the dividend after 63, then repeat: 634 / 404

Going ahead to step 3:
If we divide 634 by 404, we get 1 and a remainder of 230.
The next digit of our result is 1. 
Result so far: 1.0
If we take 404 away from 634, we end up with 230.
Bring next digit (0) of the dividend behind the 230 and repeat the process: 2300 / 404

Let's proceed to step 4:
The number 404 fits into 2300 5 times, leaving a remainder of 280.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 280 after subtracting 2020 from 2300.
Fetch the next digit (5) from the dividend, attach it to 280 and continue: 2805 / 404

Going ahead to step 5:
2805 divided by 404 is 6 with a remainder of 381.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
Subtracting 2424 from 2805 leaves us with 381.
Take the next digit (8) from the dividend and append it to 381, then repeat: 3818 / 404

On to step 6:
The number 404 fits into 3818 9 times, leaving a remainder of 182.
The number 9 becomes the next digit in our result. 
Result so far: 1569.0
Deduct 3636 from 3818 and we're left with 182.
Include the next digit (8) from the dividend after 182, then repeat: 1828 / 404

Step 7:
1828 divided by 404 is 4 with a remainder of 212.
The number 4 becomes the next digit in our result. 
Result so far: 15694.0
The remainder is 212 after subtracting 1616 from 1828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 8:
If we divide 2120 by 404, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 15694.5
Deduct 2020 from 2120 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 9:
If we divide 1000 by 404, we get 2 and a remainder of 192.
The next digit of our result is 2. 
Result so far: 15694.52
Subtracting 808 from 1000 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 10:
When dividing 1920 by 404, we get 4 with a remainder of 304.
Use 4 as the next digit of our solution. 
Result so far: 15694.524
Subtract 1616 from 1920 to get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 11:
If we divide 3040 by 404, we get 7 and a remainder of 212.
Put 7 as the next digit of the answer. 
Result so far: 15694.5247
Subtract 2828 from 3040 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

On to step 12:
If we divide 2120 by 404, we get 5 and a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 15694.52475
The remainder is 100 after subtracting 2020 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
1000 divided by 404 is 2 with a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 15694.524752
The remainder is 192 after subtracting 808 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
When dividing 1920 by 404, we get 4 with a remainder of 304.
Record the quotient 4 as the next digit in the result. 
Result so far: 15694.5247524
The remainder is 304 after subtracting 1616 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 15:
3040 divided by 404 is 7 with a remainder of 212.
Use 7 as the next digit of our solution. 
Result so far: 15694.52475247
The remainder is 212 after subtracting 2828 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final outcome is 15694.52475247, with a leftover of 2.12e-07.
