We're dividing 78415637 by 115 
Our goal is to divide 78415637 by 115.

Step 1:
115 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 115

Let's proceed to step 2:
115 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 115

Step 3:
784 divided by 115 is 6 with a remainder of 94.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 690 from 784 leaves us with 94.
Take the next digit (1) from the dividend and append it to 94, then repeat: 941 / 115

Step 4:
115 can be fit into 941 8 times, resulting in a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtracting 920 from 941 leaves us with 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 115

Moving on to step 5:
The number 115 fits into 215 1 times, leaving a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 681.0
If we subtract 115 from 215, we get 100.
Append the next digit (6) from the dividend to 100 and continue with: 1006 / 115

Let's proceed to step 6:
115 goes into 1006 8 times with a remainder of 86.
The next digit of our result is 8. 
Result so far: 6818.0
If we subtract 920 from 1006, we get 86.
Grab the next digit (3) from the dividend, add it to 86, then carry on: 863 / 115

Advancing to step 7:
115 can be fit into 863 7 times, resulting in a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 68187.0
Subtracting 805 from 863 leaves us with 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 115

Advancing to step 8:
If we divide 587 by 115, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 681875.0
Subtract 575 from 587 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
When dividing 120 by 115, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 681875.1
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
When dividing 50 by 115, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 681875.1
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
500 divided by 115 is 4 with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 681875.104
Subtracting 460 from 500 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.

Moving on to step 12:
If we divide 400 by 115, we get 3 and a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 681875.1043
If we take 345 away from 400, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
115 can be fit into 550 4 times, resulting in a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 681875.10434
Subtract 460 from 550 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
115 can be fit into 900 7 times, resulting in a remainder of 95.
Write down 7 as next digit of the result. 
Result so far: 681875.104347
The remainder is 95 after subtracting 805 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 15:
115 can be fit into 950 8 times, resulting in a remainder of 30.
The next digit of our result is 8. 
Result so far: 681875.1043478
If we subtract 920 from 950, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 16:
If we divide 300 by 115, we get 2 and a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 681875.10434782
If we take 230 away from 300, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 681875.10434782 and a remainder of 7e-08.
