We look at the division of 78803836 by 520 
We're looking to find how many times 520 goes into 78803836.

Advancing to step 1:
520 goes into 7 0 times with 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 (8) of the dividend behind the 7 and repeat the process: 78 / 520

Moving on to step 2:
520 can be fit into 78 0 times, resulting in a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 520

Advancing to step 3:
If we divide 788 by 520, we get 1 and a remainder of 268.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 520 from 788 to get 268.
Append the next digit (0) from the dividend to 268 and continue with: 2680 / 520

Moving on to step 4:
520 goes into 2680 5 times with a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we take 2600 away from 2680, we end up with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 520

Step 5:
The number 520 fits into 803 1 times, leaving a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 151.0
Subtracting 520 from 803 leaves us with 283.
Fetch the next digit (8) from the dividend, attach it to 283 and continue: 2838 / 520

Advancing to step 6:
When dividing 2838 by 520, we get 5 with a remainder of 238.
The number 5 becomes the next digit in our result. 
Result so far: 1515.0
If we take 2600 away from 2838, we end up with 238.
Append the next digit (3) from the dividend to 238 and continue with: 2383 / 520

Let's proceed to step 7:
2383 divided by 520 is 4 with a remainder of 303.
Put 4 as the next digit of the answer. 
Result so far: 15154.0
If we subtract 2080 from 2383, we get 303.
Take the next digit (6) from the dividend and append it to 303, then repeat: 3036 / 520

On to step 8:
If we divide 3036 by 520, we get 5 and a remainder of 436.
Record the quotient 5 as the next digit in the result. 
Result so far: 151545.0
Subtract 2600 from 3036 to get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 9:
520 can be fit into 4360 8 times, resulting in a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 151545.8
If we subtract 4160 from 4360, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 10:
If we divide 2000 by 520, we get 3 and a remainder of 440.
Record the quotient 3 as the next digit in the result. 
Result so far: 151545.83
The remainder is 440 after subtracting 1560 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
520 goes into 4400 8 times with a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 151545.838
Subtracting 4160 from 4400 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
2400 divided by 520 is 4 with a remainder of 320.
Use 4 as the next digit of our solution. 
Result so far: 151545.8384
Subtract 2080 from 2400 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 13:
520 goes into 3200 6 times with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 151545.83846
Deduct 3120 from 3200 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.

On to step 14:
800 divided by 520 is 1 with a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 151545.838461
Subtract 520 from 800 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 15:
When dividing 2800 by 520, we get 5 with a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 151545.8384615
Deduct 2600 from 2800 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 16:
2000 divided by 520 is 3 with a remainder of 440.
Use 3 as the next digit of our solution. 
Result so far: 151545.83846153
Subtracting 1560 from 2000 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final result is 151545.83846153 with a remainder of 4.4e-07.
