We're dividing 78517726 by 680 
We want to figure out the number of times 78517726 can be divided by 680.

Going ahead to step 1:
The number 680 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.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 680

Let's proceed to step 2:
When dividing 78 by 680, we get 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 680

Moving on to step 3:
If we divide 785 by 680, we get 1 and a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 680 from 785 and we're left with 105.
Include the next digit (1) from the dividend after 105, then repeat: 1051 / 680

Going ahead to step 4:
When dividing 1051 by 680, we get 1 with a remainder of 371.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 680 away from 1051, we end up with 371.
Take the next digit (7) from the dividend and append it to 371, then repeat: 3717 / 680

Let's proceed to step 5:
3717 divided by 680 is 5 with a remainder of 317.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Deduct 3400 from 3717 and we're left with 317.
Take the next digit (7) from the dividend and append it to 317, then repeat: 3177 / 680

Advancing to step 6:
The number 680 fits into 3177 4 times, leaving a remainder of 457.
Write down 4 as next digit of the result. 
Result so far: 1154.0
Subtracting 2720 from 3177 leaves us with 457.
Take the next digit (2) from the dividend and append it to 457, then repeat: 4572 / 680

On to step 7:
680 goes into 4572 6 times with a remainder of 492.
Use 6 as the next digit of our solution. 
Result so far: 11546.0
Subtract 4080 from 4572 to get 492.
Append the next digit (6) from the dividend to 492 and continue with: 4926 / 680

On to step 8:
680 can be fit into 4926 7 times, resulting in a remainder of 166.
Write down 7 as next digit of the result. 
Result so far: 115467.0
Deduct 4760 from 4926 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 9:
680 goes into 1660 2 times with a remainder of 300.
The next digit of our result is 2. 
Result so far: 115467.2
Deduct 1360 from 1660 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 10:
When dividing 3000 by 680, we get 4 with a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 115467.24
Subtracting 2720 from 3000 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 11:
If we divide 2800 by 680, we get 4 and a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 115467.244
The remainder is 80 after subtracting 2720 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 115467.244 with a remaining 0.008.
