We're dividing 80378580 by 710 
We want to divide 80378580 by 710.

On to step 1:
When dividing 8 by 710, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 710

Moving on to step 2:
If we divide 80 by 710, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (3) from the dividend and append it to 80, then repeat: 803 / 710

Let's proceed to step 3:
If we divide 803 by 710, we get 1 and a remainder of 93.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 710 away from 803, we end up with 93.
Take the next digit (7) from the dividend and append it to 93, then repeat: 937 / 710

Moving on to step 4:
The number 710 fits into 937 1 times, leaving a remainder of 227.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 710 away from 937, we end up with 227.
Take the next digit (8) from the dividend and append it to 227, then repeat: 2278 / 710

Moving on to step 5:
710 can be fit into 2278 3 times, resulting in a remainder of 148.
Write down 3 as next digit of the result. 
Result so far: 113.0
Deduct 2130 from 2278 and we're left with 148.
Append the next digit (5) from the dividend to 148 and continue with: 1485 / 710

Going ahead to step 6:
1485 divided by 710 is 2 with a remainder of 65.
The next digit of our result is 2. 
Result so far: 1132.0
Subtracting 1420 from 1485 leaves us with 65.
Bring next digit (8) of the dividend behind the 65 and repeat the process: 658 / 710

Moving on to step 7:
658 divided by 710 is 0 with a remainder of 658.
Use 0 as the next digit of our solution. 
Result so far: 11320.0
The remainder is 658 after subtracting 0 from 658.
Take the next digit (0) from the dividend and append it to 658, then repeat: 6580 / 710

Moving on to step 8:
When dividing 6580 by 710, we get 9 with a remainder of 190.
The number 9 becomes the next digit in our result. 
Result so far: 113209.0
The remainder is 190 after subtracting 6390 from 6580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
When dividing 1900 by 710, we get 2 with a remainder of 480.
Use 2 as the next digit of our solution. 
Result so far: 113209.2
Deduct 1420 from 1900 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 10:
The number 710 fits into 4800 6 times, leaving a remainder of 540.
The next digit of our result is 6. 
Result so far: 113209.26
The remainder is 540 after subtracting 4260 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 11:
If we divide 5400 by 710, we get 7 and a remainder of 430.
Put 7 as the next digit of the answer. 
Result so far: 113209.267
Deduct 4970 from 5400 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 12:
The number 710 fits into 4300 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 113209.2676
Subtracting 4260 from 4300 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
400 divided by 710 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 113209.2676
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 14:
If we divide 4000 by 710, we get 5 and a remainder of 450.
The number 5 becomes the next digit in our result. 
Result so far: 113209.267605
The remainder is 450 after subtracting 3550 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 15:
If we divide 4500 by 710, we get 6 and a remainder of 240.
The number 6 becomes the next digit in our result. 
Result so far: 113209.2676056
Subtract 4260 from 4500 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 16:
If we divide 2400 by 710, we get 3 and a remainder of 270.
Record the quotient 3 as the next digit in the result. 
Result so far: 113209.26760563
If we subtract 2130 from 2400, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

The quotient of the division is 113209.26760563, and the remainder is 2.7e-07.
