Let's divide 63943106 by 309
We're looking to find how many times 309 goes into 63943106.

Let's proceed to step 1:
If we divide 6 by 309, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 309

Moving on to step 2:
When dividing 63 by 309, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 309

Going ahead to step 3:
309 goes into 639 2 times with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 618 away from 639, we end up with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 309

On to step 4:
309 goes into 214 0 times with a remainder of 214.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 214, we get 214.
Fetch the next digit (3) from the dividend, attach it to 214 and continue: 2143 / 309

Advancing to step 5:
If we divide 2143 by 309, we get 6 and a remainder of 289.
Put 6 as the next digit of the answer. 
Result so far: 206.0
If we subtract 1854 from 2143, we get 289.
Grab the next digit (1) from the dividend, add it to 289, then carry on: 2891 / 309

On to step 6:
If we divide 2891 by 309, we get 9 and a remainder of 110.
The number 9 becomes the next digit in our result. 
Result so far: 2069.0
Deduct 2781 from 2891 and we're left with 110.
Include the next digit (0) from the dividend after 110, then repeat: 1100 / 309

Advancing to step 7:
If we divide 1100 by 309, we get 3 and a remainder of 173.
Put 3 as the next digit of the answer. 
Result so far: 20693.0
Subtract 927 from 1100 to get 173.
Fetch the next digit (6) from the dividend, attach it to 173 and continue: 1736 / 309

Step 8:
309 can be fit into 1736 5 times, resulting in a remainder of 191.
Record the quotient 5 as the next digit in the result. 
Result so far: 206935.0
Subtracting 1545 from 1736 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

On to step 9:
1910 divided by 309 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 206935.6
Subtracting 1854 from 1910 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
The number 309 fits into 560 1 times, leaving a remainder of 251.
The next digit of our result is 1. 
Result so far: 206935.61
The remainder is 251 after subtracting 309 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 11:
The number 309 fits into 2510 8 times, leaving a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 206935.618
If we subtract 2472 from 2510, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 12:
The number 309 fits into 380 1 times, leaving a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 206935.6181
The remainder is 71 after subtracting 309 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 13:
The number 309 fits into 710 2 times, leaving a remainder of 92.
The next digit of our result is 2. 
Result so far: 206935.61812
Subtracting 618 from 710 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 14:
920 divided by 309 is 2 with a remainder of 302.
Use 2 as the next digit of our solution. 
Result so far: 206935.618122
If we take 618 away from 920, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

The quotient of the division is 206935.618122, and the remainder is 3.02e-05.
