We look at the division of 78068194 by 520 
Our goal is to divide 78068194 by 520.

Let's proceed to step 1:
520 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 520

Advancing to step 2:
When dividing 78 by 520, we get 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 520

On to step 3:
The number 520 fits into 780 1 times, leaving a remainder of 260.
The next digit of our result is 1. 
Result so far: 1.0
If we take 520 away from 780, we end up with 260.
Bring next digit (6) of the dividend behind the 260 and repeat the process: 2606 / 520

On to step 4:
2606 divided by 520 is 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 2600 away from 2606, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 520

Going ahead to step 5:
68 divided by 520 is 0 with a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 150.0
Deduct 0 from 68 and we're left with 68.
Take the next digit (1) from the dividend and append it to 68, then repeat: 681 / 520

Advancing to step 6:
520 can be fit into 681 1 times, resulting in a remainder of 161.
The next digit of our result is 1. 
Result so far: 1501.0
If we take 520 away from 681, we end up with 161.
Fetch the next digit (9) from the dividend, attach it to 161 and continue: 1619 / 520

Advancing to step 7:
520 goes into 1619 3 times with a remainder of 59.
The next digit of our result is 3. 
Result so far: 15013.0
Deduct 1560 from 1619 and we're left with 59.
Append the next digit (4) from the dividend to 59 and continue with: 594 / 520

Going ahead to step 8:
594 divided by 520 is 1 with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 150131.0
The remainder is 74 after subtracting 520 from 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
520 can be fit into 740 1 times, resulting in a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 150131.1
If we take 520 away from 740, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 10:
The number 520 fits into 2200 4 times, leaving a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 150131.14
If we subtract 2080 from 2200, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
1200 divided by 520 is 2 with a remainder of 160.
The number 2 becomes the next digit in our result. 
Result so far: 150131.142
Subtracting 1040 from 1200 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
1600 divided by 520 is 3 with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 150131.1423
Subtract 1560 from 1600 to get 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 13:
The number 520 fits into 400 0 times, leaving a remainder of 400.
The next digit of our result is 0. 
Result so far: 150131.1423
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 14:
520 can be fit into 4000 7 times, resulting in a remainder of 360.
Put 7 as the next digit of the answer. 
Result so far: 150131.142307
Subtract 3640 from 4000 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Moving on to step 15:
If we divide 3600 by 520, we get 6 and a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 150131.1423076
If we subtract 3120 from 3600, we get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 16:
4800 divided by 520 is 9 with a remainder of 120.
The next digit of our result is 9. 
Result so far: 150131.14230769
The remainder is 120 after subtracting 4680 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Our division results in 150131.14230769 with a remaining 1.2e-07.
