We divide 78142620 by 520
We want to figure out the number of times 78142620 can be divided by 520.

Let's proceed to step 1:
When dividing 7 by 520, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 520

Advancing to step 2:
520 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
The remainder is 78 after subtracting 0 from 78.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 520

Advancing to step 3:
520 can be fit into 781 1 times, resulting in a remainder of 261.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 520 from 781 to get 261.
Append the next digit (4) from the dividend to 261 and continue with: 2614 / 520

Going ahead to step 4:
The number 520 fits into 2614 5 times, leaving a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2600 from 2614 to get 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 520

Let's proceed to step 5:
If we divide 142 by 520, we get 0 and a remainder of 142.
Put 0 as the next digit of the answer. 
Result so far: 150.0
If we take 0 away from 142, we end up with 142.
Fetch the next digit (6) from the dividend, attach it to 142 and continue: 1426 / 520

Moving on to step 6:
520 can be fit into 1426 2 times, resulting in a remainder of 386.
Record the quotient 2 as the next digit in the result. 
Result so far: 1502.0
Subtracting 1040 from 1426 leaves us with 386.
Include the next digit (2) from the dividend after 386, then repeat: 3862 / 520

Going ahead to step 7:
If we divide 3862 by 520, we get 7 and a remainder of 222.
Write down 7 as next digit of the result. 
Result so far: 15027.0
Subtracting 3640 from 3862 leaves us with 222.
Bring next digit (0) of the dividend behind the 222 and repeat the process: 2220 / 520

Let's proceed to step 8:
When dividing 2220 by 520, we get 4 with a remainder of 140.
The number 4 becomes the next digit in our result. 
Result so far: 150274.0
The remainder is 140 after subtracting 2080 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 9:
520 goes into 1400 2 times with a remainder of 360.
Write down 2 as next digit of the result. 
Result so far: 150274.2
Subtracting 1040 from 1400 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 10:
When dividing 3600 by 520, we get 6 with a remainder of 480.
The next digit of our result is 6. 
Result so far: 150274.26
The remainder is 480 after subtracting 3120 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 11:
4800 divided by 520 is 9 with a remainder of 120.
Put 9 as the next digit of the answer. 
Result so far: 150274.269
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.

Advancing to step 12:
If we divide 1200 by 520, we get 2 and a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 150274.2692
The remainder is 160 after subtracting 1040 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
520 can be fit into 1600 3 times, resulting in a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 150274.26923
Subtracting 1560 from 1600 leaves us 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.

Moving on to step 14:
When dividing 400 by 520, we get 0 with a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 150274.26923
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 15:
520 goes into 4000 7 times with a remainder of 360.
Use 7 as the next digit of our solution. 
Result so far: 150274.2692307
The remainder is 360 after subtracting 3640 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 16:
When dividing 3600 by 520, we get 6 with a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 150274.26923076
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.

In conclusion, the division gives 150274.26923076 with a balance of 4.8e-07.
