We're dividing 78447789 by 516 
Our goal is to divide 78447789 by 516.

Going ahead to step 1:
7 divided by 516 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 516

Step 2:
If we divide 78 by 516, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (4) of the dividend behind the 78 and repeat the process: 784 / 516

Advancing to step 3:
784 divided by 516 is 1 with a remainder of 268.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 516 from 784 and we're left with 268.
Grab the next digit (4) from the dividend, add it to 268, then carry on: 2684 / 516

Let's proceed to step 4:
The number 516 fits into 2684 5 times, leaving a remainder of 104.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 2580 away from 2684, we end up with 104.
Append the next digit (7) from the dividend to 104 and continue with: 1047 / 516

Let's proceed to step 5:
When dividing 1047 by 516, we get 2 with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
Subtracting 1032 from 1047 leaves us with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 516

Step 6:
157 divided by 516 is 0 with a remainder of 157.
Record the quotient 0 as the next digit in the result. 
Result so far: 1520.0
Subtract 0 from 157 to get 157.
Fetch the next digit (8) from the dividend, attach it to 157 and continue: 1578 / 516

Advancing to step 7:
If we divide 1578 by 516, we get 3 and a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 15203.0
Deduct 1548 from 1578 and we're left with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 516

Going ahead to step 8:
309 divided by 516 is 0 with a remainder of 309.
Use 0 as the next digit of our solution. 
Result so far: 152030.0
If we subtract 0 from 309, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 9:
If we divide 3090 by 516, we get 5 and a remainder of 510.
Write down 5 as next digit of the result. 
Result so far: 152030.5
The remainder is 510 after subtracting 2580 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 10:
If we divide 5100 by 516, we get 9 and a remainder of 456.
Put 9 as the next digit of the answer. 
Result so far: 152030.59
If we take 4644 away from 5100, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 11:
516 can be fit into 4560 8 times, resulting in a remainder of 432.
The next digit of our result is 8. 
Result so far: 152030.598
The remainder is 432 after subtracting 4128 from 4560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Going ahead to step 12:
516 can be fit into 4320 8 times, resulting in a remainder of 192.
The next digit of our result is 8. 
Result so far: 152030.5988
If we subtract 4128 from 4320, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Our division results in 152030.5988 with a remaining 0.00192.
