78685172 divided by 702 
Our goal is to divide 78685172 by 702.

Step 1:
The number 702 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.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 702

Advancing to step 2:
The number 702 fits into 78 0 times, leaving a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Append the next digit (6) from the dividend to 78 and continue with: 786 / 702

Going ahead to step 3:
When dividing 786 by 702, we get 1 with a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 84 after subtracting 702 from 786.
Bring next digit (8) of the dividend behind the 84 and repeat the process: 848 / 702

Going ahead to step 4:
848 divided by 702 is 1 with a remainder of 146.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 702 away from 848, we end up with 146.
Bring next digit (5) of the dividend behind the 146 and repeat the process: 1465 / 702

On to step 5:
When dividing 1465 by 702, we get 2 with a remainder of 61.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
If we subtract 1404 from 1465, we get 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 702

Moving on to step 6:
611 divided by 702 is 0 with a remainder of 611.
The number 0 becomes the next digit in our result. 
Result so far: 1120.0
Subtract 0 from 611 to get 611.
Append the next digit (7) from the dividend to 611 and continue with: 6117 / 702

Let's proceed to step 7:
If we divide 6117 by 702, we get 8 and a remainder of 501.
The next digit of our result is 8. 
Result so far: 11208.0
If we take 5616 away from 6117, we end up with 501.
Fetch the next digit (2) from the dividend, attach it to 501 and continue: 5012 / 702

On to step 8:
702 goes into 5012 7 times with a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 112087.0
Deduct 4914 from 5012 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 9:
If we divide 980 by 702, we get 1 and a remainder of 278.
The number 1 becomes the next digit in our result. 
Result so far: 112087.1
Subtracting 702 from 980 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 10:
702 goes into 2780 3 times with a remainder of 674.
Use 3 as the next digit of our solution. 
Result so far: 112087.13
Deduct 2106 from 2780 and we're left with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Going ahead to step 11:
If we divide 6740 by 702, we get 9 and a remainder of 422.
Put 9 as the next digit of the answer. 
Result so far: 112087.139
Deduct 6318 from 6740 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Moving on to step 12:
4220 divided by 702 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 112087.1396
If we subtract 4212 from 4220, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
80 divided by 702 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 112087.1396
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
702 goes into 800 1 times with a remainder of 98.
The number 1 becomes the next digit in our result. 
Result so far: 112087.139601
Subtract 702 from 800 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 15:
When dividing 980 by 702, we get 1 with a remainder of 278.
The number 1 becomes the next digit in our result. 
Result so far: 112087.1396011
Subtracting 702 from 980 leaves us with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

In conclusion, the division gives 112087.1396011 with a balance of 2.78e-06.
