Let's divide 78109731 by 710
We want to divide 78109731 by 710.

Step 1:
The number 710 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 710

Advancing to step 2:
78 divided by 710 is 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 710

Moving on to step 3:
If we divide 781 by 710, we get 1 and a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 710 from 781 and we're left with 71.
Grab the next digit (0) from the dividend, add it to 71, then carry on: 710 / 710

Going ahead to step 4:
710 goes into 710 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 710 from 710, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 710

On to step 5:
9 divided by 710 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 110.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 710

Let's proceed to step 6:
When dividing 97 by 710, we get 0 with a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 1100.0
The remainder is 97 after subtracting 0 from 97.
Grab the next digit (3) from the dividend, add it to 97, then carry on: 973 / 710

Going ahead to step 7:
If we divide 973 by 710, we get 1 and a remainder of 263.
Put 1 as the next digit of the answer. 
Result so far: 11001.0
If we subtract 710 from 973, we get 263.
Grab the next digit (1) from the dividend, add it to 263, then carry on: 2631 / 710

On to step 8:
The number 710 fits into 2631 3 times, leaving a remainder of 501.
Use 3 as the next digit of our solution. 
Result so far: 110013.0
Deduct 2130 from 2631 and we're left with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Going ahead to step 9:
If we divide 5010 by 710, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 110013.7
Subtract 4970 from 5010 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
400 divided by 710 is 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 110013.7
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.

Step 11:
The number 710 fits into 4000 5 times, leaving a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 110013.705
If we take 3550 away from 4000, we end up 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.

Going ahead to step 12:
710 can be fit into 4500 6 times, resulting in a remainder of 240.
Record the quotient 6 as the next digit in the result. 
Result so far: 110013.7056
If we subtract 4260 from 4500, we 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 13:
710 can be fit into 2400 3 times, resulting in a remainder of 270.
Put 3 as the next digit of the answer. 
Result so far: 110013.70563
Subtracting 2130 from 2400 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 14:
If we divide 2700 by 710, we get 3 and a remainder of 570.
The number 3 becomes the next digit in our result. 
Result so far: 110013.705633
Subtracting 2130 from 2700 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

The final result is 110013.705633 with a remainder of 5.7e-05.
