We're dividing 762109 by 78 
We want to figure out the number of times 762109 can be divided by 78.

Let's proceed to step 1:
78 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
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 78

Moving on to step 2:
78 goes into 76 0 times with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Take the next digit (2) from the dividend and append it to 76, then repeat: 762 / 78

Going ahead to step 3:
When dividing 762 by 78, we get 9 with a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 60 after subtracting 702 from 762.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 78

Moving on to step 4:
The number 78 fits into 601 7 times, leaving a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we take 546 away from 601, we end up with 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 78

On to step 5:
When dividing 550 by 78, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 977.0
The remainder is 4 after subtracting 546 from 550.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 78

Moving on to step 6:
49 divided by 78 is 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 9770.0
Subtracting 0 from 49 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
The number 78 fits into 490 6 times, leaving a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 9770.6
Deduct 468 from 490 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 9770.62
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
The number 78 fits into 640 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 9770.628
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
When dividing 160 by 78, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 9770.6282
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
If we divide 40 by 78, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9770.6282
Deduct 0 from 40 and we're left 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.

Advancing to step 12:
The number 78 fits into 400 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 9770.628205
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
78 goes into 100 1 times with a remainder of 22.
The next digit of our result is 1. 
Result so far: 9770.6282051
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
78 goes into 220 2 times with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 9770.62820512
The remainder is 64 after subtracting 156 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 9770.62820512, and the remainder is 6.4e-08.
