We look at the division of 755 by 78 
We want to figure out the number of times 755 can be divided by 78.

Advancing to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 78

Moving on to step 2:
If we divide 75 by 78, we get 0 and a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (5) of the dividend behind the 75 and repeat the process: 755 / 78

Let's proceed to step 3:
If we divide 755 by 78, we get 9 and a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 702 from 755 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 4:
When dividing 530 by 78, we get 6 with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 9.6
Subtracting 468 from 530 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 5:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 9.67
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 6:
If we divide 740 by 78, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 9.679
Deduct 702 from 740 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
78 goes into 380 4 times with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 9.6794
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
When dividing 680 by 78, we get 8 with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 9.67948
Deduct 624 from 680 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 9.679487
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
If we divide 140 by 78, we get 1 and a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 9.6794871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
If we divide 620 by 78, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 9.67948717
Deduct 546 from 620 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 9.67948717 and a remainder of 7.4e-08.
