We look at the division of 6391293 by 305 
Let's see how many times 305 fits into 6391293.

Advancing to step 1:
305 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 305

Let's proceed to step 2:
If we divide 63 by 305, we get 0 and a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 305

Step 3:
305 can be fit into 639 2 times, resulting in a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 610 away from 639, we end up with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 305

Let's proceed to step 4:
305 can be fit into 291 0 times, resulting in a remainder of 291.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 291 leaves us with 291.
Take the next digit (2) from the dividend and append it to 291, then repeat: 2912 / 305

Moving on to step 5:
When dividing 2912 by 305, we get 9 with a remainder of 167.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
Subtracting 2745 from 2912 leaves us with 167.
Take the next digit (9) from the dividend and append it to 167, then repeat: 1679 / 305

Advancing to step 6:
305 can be fit into 1679 5 times, resulting in a remainder of 154.
The next digit of our result is 5. 
Result so far: 2095.0
If we take 1525 away from 1679, we end up with 154.
Append the next digit (3) from the dividend to 154 and continue with: 1543 / 305

Step 7:
305 can be fit into 1543 5 times, resulting in a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 20955.0
Deduct 1525 from 1543 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 8:
305 goes into 180 0 times with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 20955.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 9:
1800 divided by 305 is 5 with a remainder of 275.
The next digit of our result is 5. 
Result so far: 20955.05
Deduct 1525 from 1800 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Let's proceed to step 10:
305 can be fit into 2750 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 20955.059
Subtracting 2745 from 2750 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
If we divide 50 by 305, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 20955.059
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
When dividing 500 by 305, we get 1 with a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 20955.05901
If we subtract 305 from 500, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 13:
305 can be fit into 1950 6 times, resulting in a remainder of 120.
Write down 6 as next digit of the result. 
Result so far: 20955.059016
Subtract 1830 from 1950 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 14:
305 can be fit into 1200 3 times, resulting in a remainder of 285.
Use 3 as the next digit of our solution. 
Result so far: 20955.0590163
The remainder is 285 after subtracting 915 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 15:
305 goes into 2850 9 times with a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 20955.05901639
If we take 2745 away from 2850, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Our division results in 20955.05901639 with a remaining 1.05e-07.
