64312 divided by 51 
We want to figure out the number of times 64312 can be divided by 51.

Let's proceed to step 1:
51 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 51

Step 2:
The number 51 fits into 64 1 times, leaving a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 13 after subtracting 51 from 64.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 51

Step 3:
When dividing 133 by 51, we get 2 with a remainder of 31.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 102 from 133 and we're left with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 51

Step 4:
If we divide 311 by 51, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtracting 306 from 311 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 51

Moving on to step 5:
51 can be fit into 52 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1261.0
If we subtract 51 from 52, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
If we divide 10 by 51, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1261.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
100 divided by 51 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1261.01
If we take 51 away from 100, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
If we divide 490 by 51, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 1261.019
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
51 goes into 310 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 1261.0196
Subtracting 306 from 310 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 1261.0196
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
51 goes into 400 7 times with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 1261.019607
Subtract 357 from 400 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 12:
51 can be fit into 430 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1261.0196078
Deduct 408 from 430 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1261.01960784
Subtracting 204 from 220 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 1261.01960784, and the remainder is 1.6e-08.
