Let's divide 84142709 by 516
We want to divide 84142709 by 516.

Going ahead to step 1:
516 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 516

Advancing to step 2:
When dividing 84 by 516, we get 0 with a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Bring next digit (1) of the dividend behind the 84 and repeat the process: 841 / 516

On to step 3:
841 divided by 516 is 1 with a remainder of 325.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 325 after subtracting 516 from 841.
Include the next digit (4) from the dividend after 325, then repeat: 3254 / 516

Step 4:
3254 divided by 516 is 6 with a remainder of 158.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 3096 from 3254 to get 158.
Grab the next digit (2) from the dividend, add it to 158, then carry on: 1582 / 516

Advancing to step 5:
If we divide 1582 by 516, we get 3 and a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
The remainder is 34 after subtracting 1548 from 1582.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 516

On to step 6:
516 goes into 347 0 times with a remainder of 347.
The number 0 becomes the next digit in our result. 
Result so far: 1630.0
Subtracting 0 from 347 leaves us with 347.
Include the next digit (0) from the dividend after 347, then repeat: 3470 / 516

Moving on to step 7:
The number 516 fits into 3470 6 times, leaving a remainder of 374.
Record the quotient 6 as the next digit in the result. 
Result so far: 16306.0
Deduct 3096 from 3470 and we're left with 374.
Grab the next digit (9) from the dividend, add it to 374, then carry on: 3749 / 516

Step 8:
516 can be fit into 3749 7 times, resulting in a remainder of 137.
The next digit of our result is 7. 
Result so far: 163067.0
Subtract 3612 from 3749 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 9:
If we divide 1370 by 516, we get 2 and a remainder of 338.
Use 2 as the next digit of our solution. 
Result so far: 163067.2
Deduct 1032 from 1370 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 10:
516 can be fit into 3380 6 times, resulting in a remainder of 284.
Use 6 as the next digit of our solution. 
Result so far: 163067.26
Subtract 3096 from 3380 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 11:
516 can be fit into 2840 5 times, resulting in a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 163067.265
If we take 2580 away from 2840, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 12:
516 can be fit into 2600 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 163067.2655
The remainder is 20 after subtracting 2580 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 163067.2655 with a remainder of 0.0002.
