31319 divided by 51 
Let's see how many times 51 fits into 31319.

Let's proceed to step 1:
When dividing 3 by 51, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 51

Step 2:
51 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 51

Step 3:
51 goes into 313 6 times with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 306 away from 313, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 51

Going ahead to step 4:
If we divide 71 by 51, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
The remainder is 20 after subtracting 51 from 71.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 51

Step 5:
51 can be fit into 209 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 614.0
Deduct 204 from 209 and we're left 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.

Let's proceed to step 6:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 614.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
If we divide 500 by 51, we get 9 and a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 614.09
If we subtract 459 from 500, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 8:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 614.098
If we subtract 408 from 410, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 51 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 614.098
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
51 goes into 200 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 614.09803
Subtract 153 from 200 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
If we divide 470 by 51, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 614.098039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
51 can be fit into 110 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 614.0980392
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
If we divide 80 by 51, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 614.09803921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 614.09803921, with a leftover of 2.9e-08.
