We look at the division of 6390317 by 431 
We want to figure out the number of times 6390317 can be divided by 431.

On to step 1:
6 divided by 431 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 431

Going ahead to step 2:
431 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 431

Let's proceed to step 3:
431 can be fit into 639 1 times, resulting in a remainder of 208.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 431 from 639, we get 208.
Include the next digit (0) from the dividend after 208, then repeat: 2080 / 431

Moving on to step 4:
When dividing 2080 by 431, we get 4 with a remainder of 356.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 1724 from 2080 and we're left with 356.
Take the next digit (3) from the dividend and append it to 356, then repeat: 3563 / 431

Let's proceed to step 5:
The number 431 fits into 3563 8 times, leaving a remainder of 115.
Use 8 as the next digit of our solution. 
Result so far: 148.0
If we take 3448 away from 3563, we end up with 115.
Take the next digit (1) from the dividend and append it to 115, then repeat: 1151 / 431

Going ahead to step 6:
The number 431 fits into 1151 2 times, leaving a remainder of 289.
Put 2 as the next digit of the answer. 
Result so far: 1482.0
If we take 862 away from 1151, we end up with 289.
Include the next digit (7) from the dividend after 289, then repeat: 2897 / 431

Step 7:
2897 divided by 431 is 6 with a remainder of 311.
Write down 6 as next digit of the result. 
Result so far: 14826.0
Subtract 2586 from 2897 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 8:
431 goes into 3110 7 times with a remainder of 93.
The next digit of our result is 7. 
Result so far: 14826.7
Deduct 3017 from 3110 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 9:
431 can be fit into 930 2 times, resulting in a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 14826.72
If we subtract 862 from 930, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
When dividing 680 by 431, we get 1 with a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 14826.721
Subtracting 431 from 680 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 11:
431 can be fit into 2490 5 times, resulting in a remainder of 335.
Put 5 as the next digit of the answer. 
Result so far: 14826.7215
Subtracting 2155 from 2490 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

On to step 12:
When dividing 3350 by 431, we get 7 with a remainder of 333.
The next digit of our result is 7. 
Result so far: 14826.72157
Deduct 3017 from 3350 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Advancing to step 13:
When dividing 3330 by 431, we get 7 with a remainder of 313.
Record the quotient 7 as the next digit in the result. 
Result so far: 14826.721577
Deduct 3017 from 3330 and we're left with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Our division results in 14826.721577 with a remaining 3.13e-05.
