Let's divide 86782545 by 520
We're looking to find how many times 520 goes into 86782545.

Step 1:
The number 520 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 520

Step 2:
86 divided by 520 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 520

On to step 3:
The number 520 fits into 867 1 times, leaving a remainder of 347.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 520 from 867 and we're left with 347.
Bring next digit (8) of the dividend behind the 347 and repeat the process: 3478 / 520

Let's proceed to step 4:
520 goes into 3478 6 times with a remainder of 358.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 3120 from 3478 leaves us with 358.
Bring next digit (2) of the dividend behind the 358 and repeat the process: 3582 / 520

Advancing to step 5:
If we divide 3582 by 520, we get 6 and a remainder of 462.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
If we subtract 3120 from 3582, we get 462.
Fetch the next digit (5) from the dividend, attach it to 462 and continue: 4625 / 520

Going ahead to step 6:
520 goes into 4625 8 times with a remainder of 465.
The number 8 becomes the next digit in our result. 
Result so far: 1668.0
Subtract 4160 from 4625 to get 465.
Grab the next digit (4) from the dividend, add it to 465, then carry on: 4654 / 520

Advancing to step 7:
520 can be fit into 4654 8 times, resulting in a remainder of 494.
Write down 8 as next digit of the result. 
Result so far: 16688.0
If we subtract 4160 from 4654, we get 494.
Fetch the next digit (5) from the dividend, attach it to 494 and continue: 4945 / 520

Advancing to step 8:
When dividing 4945 by 520, we get 9 with a remainder of 265.
Use 9 as the next digit of our solution. 
Result so far: 166889.0
Subtract 4680 from 4945 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 9:
2650 divided by 520 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 166889.5
Subtracting 2600 from 2650 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 520, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 166889.5
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 11:
520 can be fit into 5000 9 times, resulting in a remainder of 320.
Put 9 as the next digit of the answer. 
Result so far: 166889.509
If we take 4680 away from 5000, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 12:
When dividing 3200 by 520, we get 6 with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 166889.5096
Subtracting 3120 from 3200 leaves us 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.

Step 13:
If we divide 800 by 520, we get 1 and a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 166889.50961
If we subtract 520 from 800, we 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.

Step 14:
When dividing 2800 by 520, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 166889.509615
If we take 2600 away from 2800, we end up 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.

Advancing to step 15:
520 can be fit into 2000 3 times, resulting in a remainder of 440.
Use 3 as the next digit of our solution. 
Result so far: 166889.5096153
Deduct 1560 from 2000 and we're left 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.

Let's proceed to step 16:
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: 166889.50961538
Deduct 4160 from 4400 and we're left 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.

The final outcome is 166889.50961538, with a leftover of 2.4e-07.
