We're dividing 87754430 by 520 
Let's see how many times 520 fits into 87754430.

Advancing to step 1:
When dividing 8 by 520, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 520

On to step 2:
520 can be fit into 87 0 times, resulting in a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 520

Going ahead to step 3:
When dividing 877 by 520, we get 1 with a remainder of 357.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 357 after subtracting 520 from 877.
Grab the next digit (5) from the dividend, add it to 357, then carry on: 3575 / 520

Moving on to step 4:
If we divide 3575 by 520, we get 6 and a remainder of 455.
The next digit of our result is 6. 
Result so far: 16.0
Subtract 3120 from 3575 to get 455.
Fetch the next digit (4) from the dividend, attach it to 455 and continue: 4554 / 520

Moving on to step 5:
4554 divided by 520 is 8 with a remainder of 394.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
If we subtract 4160 from 4554, we get 394.
Grab the next digit (4) from the dividend, add it to 394, then carry on: 3944 / 520

Step 6:
520 goes into 3944 7 times with a remainder of 304.
The next digit of our result is 7. 
Result so far: 1687.0
Deduct 3640 from 3944 and we're left with 304.
Fetch the next digit (3) from the dividend, attach it to 304 and continue: 3043 / 520

On to step 7:
The number 520 fits into 3043 5 times, leaving a remainder of 443.
The next digit of our result is 5. 
Result so far: 16875.0
If we take 2600 away from 3043, we end up with 443.
Take the next digit (0) from the dividend and append it to 443, then repeat: 4430 / 520

Step 8:
520 goes into 4430 8 times with a remainder of 270.
Use 8 as the next digit of our solution. 
Result so far: 168758.0
The remainder is 270 after subtracting 4160 from 4430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 9:
When dividing 2700 by 520, we get 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 168758.5
Subtract 2600 from 2700 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
The number 520 fits into 1000 1 times, leaving a remainder of 480.
Record the quotient 1 as the next digit in the result. 
Result so far: 168758.51
If we subtract 520 from 1000, 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.

On to step 11:
4800 divided by 520 is 9 with a remainder of 120.
Record the quotient 9 as the next digit in the result. 
Result so far: 168758.519
If we subtract 4680 from 4800, 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.

Let's proceed to step 12:
The number 520 fits into 1200 2 times, leaving a remainder of 160.
The next digit of our result is 2. 
Result so far: 168758.5192
Deduct 1040 from 1200 and we're left 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.

Moving on to step 13:
520 goes into 1600 3 times with a remainder of 40.
The next digit of our result is 3. 
Result so far: 168758.51923
If we take 1560 away from 1600, we end up 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.

Let's proceed to step 14:
520 goes into 400 0 times with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 168758.51923
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.

On to step 15:
520 goes into 4000 7 times with a remainder of 360.
Write down 7 as next digit of the result. 
Result so far: 168758.5192307
Deduct 3640 from 4000 and we're left 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.

Going ahead to step 16:
520 can be fit into 3600 6 times, resulting in a remainder of 480.
The number 6 becomes the next digit in our result. 
Result so far: 168758.51923076
Subtracting 3120 from 3600 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The final outcome is 168758.51923076, with a leftover of 4.8e-07.
