We're dividing 78109072 by 104 
Our goal is to divide 78109072 by 104.

Going ahead to step 1:
The number 104 fits into 7 0 times, leaving 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 / 104

Step 2:
104 goes into 78 0 times with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 104

Let's proceed to step 3:
The number 104 fits into 781 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 728 from 781, we get 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 104

Advancing to step 4:
104 can be fit into 530 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 75.0
Subtracting 520 from 530 leaves us with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 104

Moving on to step 5:
When dividing 109 by 104, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 751.0
If we take 104 away from 109, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 104

On to step 6:
The number 104 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7510.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (7) from the dividend after 50, then repeat: 507 / 104

Going ahead to step 7:
The number 104 fits into 507 4 times, leaving a remainder of 91.
The next digit of our result is 4. 
Result so far: 75104.0
Subtracting 416 from 507 leaves us with 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 104

Step 8:
The number 104 fits into 912 8 times, leaving a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 751048.0
Deduct 832 from 912 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
104 goes into 800 7 times with a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 751048.7
Deduct 728 from 800 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
720 divided by 104 is 6 with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 751048.76
If we subtract 624 from 720, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 11:
104 goes into 960 9 times with a remainder of 24.
The next digit of our result is 9. 
Result so far: 751048.769
If we subtract 936 from 960, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
240 divided by 104 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 751048.7692
The remainder is 32 after subtracting 208 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 104 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 751048.76923
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
When dividing 80 by 104, we get 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 751048.76923
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
104 can be fit into 800 7 times, resulting in a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 751048.7692307
If we take 728 away from 800, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 16:
If we divide 720 by 104, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 751048.76923076
If we take 624 away from 720, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The final outcome is 751048.76923076, with a leftover of 9.6e-08.
