Let's divide 514279 by 12
We're looking to find how many times 12 goes into 514279.

On to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 12

Advancing to step 2:
If we divide 51 by 12, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 48 away from 51, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 12

Going ahead to step 3:
When dividing 34 by 12, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
The remainder is 10 after subtracting 24 from 34.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Going ahead to step 4:
12 can be fit into 102 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 428.0
Deduct 96 from 102 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 12

Advancing to step 5:
12 goes into 67 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 4285.0
Subtract 60 from 67 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Step 6:
When dividing 79 by 12, we get 6 with a remainder of 7.
Use 6 as the next digit of our solution. 
Result so far: 42856.0
If we take 72 away from 79, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
12 can be fit into 70 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 42856.5
Subtract 60 from 70 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 42856.58
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 42856.583
Deduct 36 from 40 and we're left 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.

Step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 42856.5833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 42856.5833 and a remainder of 4e-05.
