8780817 divided by 715 
Our goal is to divide 8780817 by 715.

Advancing to step 1:
If we divide 8 by 715, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 715

Moving on to step 2:
715 goes into 87 0 times with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (8) from the dividend, add it to 87, then carry on: 878 / 715

Moving on to step 3:
The number 715 fits into 878 1 times, leaving a remainder of 163.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 715 from 878 and we're left with 163.
Append the next digit (0) from the dividend to 163 and continue with: 1630 / 715

On to step 4:
When dividing 1630 by 715, we get 2 with a remainder of 200.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 1430 from 1630, we get 200.
Take the next digit (8) from the dividend and append it to 200, then repeat: 2008 / 715

Going ahead to step 5:
715 goes into 2008 2 times with a remainder of 578.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 1430 from 2008, we get 578.
Grab the next digit (1) from the dividend, add it to 578, then carry on: 5781 / 715

Step 6:
When dividing 5781 by 715, we get 8 with a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 1228.0
If we subtract 5720 from 5781, we get 61.
Include the next digit (7) from the dividend after 61, then repeat: 617 / 715

Going ahead to step 7:
715 goes into 617 0 times with a remainder of 617.
The number 0 becomes the next digit in our result. 
Result so far: 12280.0
Subtract 0 from 617 to get 617.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6170, and continue the process.

Step 8:
The number 715 fits into 6170 8 times, leaving a remainder of 450.
Put 8 as the next digit of the answer. 
Result so far: 12280.8
Deduct 5720 from 6170 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 9:
715 can be fit into 4500 6 times, resulting in a remainder of 210.
The number 6 becomes the next digit in our result. 
Result so far: 12280.86
If we subtract 4290 from 4500, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
715 can be fit into 2100 2 times, resulting in a remainder of 670.
Put 2 as the next digit of the answer. 
Result so far: 12280.862
Subtract 1430 from 2100 to get 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Step 11:
715 goes into 6700 9 times with a remainder of 265.
The next digit of our result is 9. 
Result so far: 12280.8629
Subtract 6435 from 6700 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 12:
When dividing 2650 by 715, we get 3 with a remainder of 505.
Write down 3 as next digit of the result. 
Result so far: 12280.86293
Subtracting 2145 from 2650 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Let's proceed to step 13:
5050 divided by 715 is 7 with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 12280.862937
If we subtract 5005 from 5050, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
715 goes into 450 0 times with a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 12280.862937
Subtract 0 from 450 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Advancing to step 15:
715 goes into 4500 6 times with a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 12280.86293706
If we subtract 4290 from 4500, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final result is 12280.86293706 with a remainder of 2.1e-07.
