We look at the division of 63795257 by 309 
Our goal is to divide 63795257 by 309.

Step 1:
309 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our 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 / 309

Advancing to step 2:
309 can be fit into 63 0 times, resulting in 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.
Append the next digit (7) from the dividend to 63 and continue with: 637 / 309

On to step 3:
637 divided by 309 is 2 with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 618 from 637 leaves us with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 309

Step 4:
199 divided by 309 is 0 with a remainder of 199.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 199 after subtracting 0 from 199.
Grab the next digit (5) from the dividend, add it to 199, then carry on: 1995 / 309

Advancing to step 5:
309 goes into 1995 6 times with a remainder of 141.
The next digit of our result is 6. 
Result so far: 206.0
Subtracting 1854 from 1995 leaves us with 141.
Grab the next digit (2) from the dividend, add it to 141, then carry on: 1412 / 309

Let's proceed to step 6:
When dividing 1412 by 309, we get 4 with a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 2064.0
If we subtract 1236 from 1412, we get 176.
Append the next digit (5) from the dividend to 176 and continue with: 1765 / 309

Step 7:
The number 309 fits into 1765 5 times, leaving a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 20645.0
If we subtract 1545 from 1765, we get 220.
Bring next digit (7) of the dividend behind the 220 and repeat the process: 2207 / 309

Step 8:
309 goes into 2207 7 times with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 206457.0
Subtracting 2163 from 2207 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
309 can be fit into 440 1 times, resulting in a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 206457.1
Subtract 309 from 440 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 10:
1310 divided by 309 is 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 206457.14
The remainder is 74 after subtracting 1236 from 1310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
740 divided by 309 is 2 with a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 206457.142
Deduct 618 from 740 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 12:
The number 309 fits into 1220 3 times, leaving a remainder of 293.
Use 3 as the next digit of our solution. 
Result so far: 206457.1423
Deduct 927 from 1220 and we're left with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 13:
2930 divided by 309 is 9 with a remainder of 149.
The number 9 becomes the next digit in our result. 
Result so far: 206457.14239
If we take 2781 away from 2930, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Moving on to step 14:
The number 309 fits into 1490 4 times, leaving a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 206457.142394
If we take 1236 away from 1490, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 15:
If we divide 2540 by 309, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 206457.1423948
If we take 2472 away from 2540, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 16:
When dividing 680 by 309, we get 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 206457.14239482
Deduct 618 from 680 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final outcome is 206457.14239482, with a leftover of 6.2e-08.
