Let's divide 64314255 by 312
Our goal is to divide 64314255 by 312.

Advancing to step 1:
312 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 (4) from the dividend to 6 and continue with: 64 / 312

Let's proceed to step 2:
If we divide 64 by 312, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 312

Step 3:
312 can be fit into 643 2 times, resulting in a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 19 after subtracting 624 from 643.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 312

Advancing to step 4:
When dividing 191 by 312, we get 0 with a remainder of 191.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 191, we get 191.
Grab the next digit (4) from the dividend, add it to 191, then carry on: 1914 / 312

Moving on to step 5:
If we divide 1914 by 312, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 206.0
Subtract 1872 from 1914 to get 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 312

Step 6:
312 can be fit into 422 1 times, resulting in a remainder of 110.
The next digit of our result is 1. 
Result so far: 2061.0
Subtracting 312 from 422 leaves us with 110.
Append the next digit (5) from the dividend to 110 and continue with: 1105 / 312

Step 7:
If we divide 1105 by 312, we get 3 and a remainder of 169.
Use 3 as the next digit of our solution. 
Result so far: 20613.0
Deduct 936 from 1105 and we're left with 169.
Include the next digit (5) from the dividend after 169, then repeat: 1695 / 312

Step 8:
The number 312 fits into 1695 5 times, leaving a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 206135.0
The remainder is 135 after subtracting 1560 from 1695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 9:
312 can be fit into 1350 4 times, resulting in a remainder of 102.
The number 4 becomes the next digit in our result. 
Result so far: 206135.4
Subtract 1248 from 1350 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 10:
1020 divided by 312 is 3 with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 206135.43
The remainder is 84 after subtracting 936 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 11:
If we divide 840 by 312, we get 2 and a remainder of 216.
Use 2 as the next digit of our solution. 
Result so far: 206135.432
Subtract 624 from 840 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Moving on to step 12:
312 goes into 2160 6 times with a remainder of 288.
The number 6 becomes the next digit in our result. 
Result so far: 206135.4326
If we subtract 1872 from 2160, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 13:
If we divide 2880 by 312, we get 9 and a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 206135.43269
If we take 2808 away from 2880, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
When dividing 720 by 312, we get 2 with a remainder of 96.
Write down 2 as next digit of the result. 
Result so far: 206135.432692
If we take 624 away from 720, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 15:
312 goes into 960 3 times with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 206135.4326923
If we subtract 936 from 960, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 16:
240 divided by 312 is 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 206135.4326923
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The quotient of the division is 206135.4326923, and the remainder is 2.4e-07.
