We're dividing 78502109 by 716 
We want to divide 78502109 by 716.

Going ahead to step 1:
The number 716 fits into 7 0 times, leaving 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.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 716

Let's proceed to step 2:
78 divided by 716 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 716

Let's proceed to step 3:
The number 716 fits into 785 1 times, leaving a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 716 from 785 to get 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 716

Going ahead to step 4:
716 goes into 690 0 times with a remainder of 690.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 690 to get 690.
Take the next digit (2) from the dividend and append it to 690, then repeat: 6902 / 716

On to step 5:
6902 divided by 716 is 9 with a remainder of 458.
Write down 9 as next digit of the result. 
Result so far: 109.0
Deduct 6444 from 6902 and we're left with 458.
Fetch the next digit (1) from the dividend, attach it to 458 and continue: 4581 / 716

Going ahead to step 6:
716 can be fit into 4581 6 times, resulting in a remainder of 285.
Record the quotient 6 as the next digit in the result. 
Result so far: 1096.0
If we take 4296 away from 4581, we end up with 285.
Take the next digit (0) from the dividend and append it to 285, then repeat: 2850 / 716

Let's proceed to step 7:
The number 716 fits into 2850 3 times, leaving a remainder of 702.
The next digit of our result is 3. 
Result so far: 10963.0
If we take 2148 away from 2850, we end up with 702.
Fetch the next digit (9) from the dividend, attach it to 702 and continue: 7029 / 716

Moving on to step 8:
When dividing 7029 by 716, we get 9 with a remainder of 585.
The next digit of our result is 9. 
Result so far: 109639.0
Subtract 6444 from 7029 to get 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Advancing to step 9:
5850 divided by 716 is 8 with a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 109639.8
Deduct 5728 from 5850 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 10:
The number 716 fits into 1220 1 times, leaving a remainder of 504.
The next digit of our result is 1. 
Result so far: 109639.81
Deduct 716 from 1220 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 11:
If we divide 5040 by 716, we get 7 and a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 109639.817
Subtracting 5012 from 5040 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
716 goes into 280 0 times with a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 109639.817
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
If we divide 2800 by 716, we get 3 and a remainder of 652.
The number 3 becomes the next digit in our result. 
Result so far: 109639.81703
If we subtract 2148 from 2800, we get 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Going ahead to step 14:
When dividing 6520 by 716, we get 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 109639.817039
Subtract 6444 from 6520 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
When dividing 760 by 716, we get 1 with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 109639.8170391
If we take 716 away from 760, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 16:
716 goes into 440 0 times with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 109639.8170391
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final result is 109639.8170391 with a remainder of 4.4e-07.
