We look at the division of 45266877 by 520 
Our goal is to divide 45266877 by 520.

On to step 1:
If we divide 4 by 520, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 520

Step 2:
520 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Include the next digit (2) from the dividend after 45, then repeat: 452 / 520

Step 3:
452 divided by 520 is 0 with a remainder of 452.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 452 to get 452.
Include the next digit (6) from the dividend after 452, then repeat: 4526 / 520

Moving on to step 4:
520 goes into 4526 8 times with a remainder of 366.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 4160 from 4526 and we're left with 366.
Include the next digit (6) from the dividend after 366, then repeat: 3666 / 520

Advancing to step 5:
The number 520 fits into 3666 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 3640 from 3666 leaves us with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 520

Step 6:
When dividing 268 by 520, we get 0 with a remainder of 268.
Write down 0 as next digit of the result. 
Result so far: 870.0
Subtracting 0 from 268 leaves us with 268.
Fetch the next digit (7) from the dividend, attach it to 268 and continue: 2687 / 520

Going ahead to step 7:
The number 520 fits into 2687 5 times, leaving a remainder of 87.
Put 5 as the next digit of the answer. 
Result so far: 8705.0
Deduct 2600 from 2687 and we're left with 87.
Append the next digit (7) from the dividend to 87 and continue with: 877 / 520

Advancing to step 8:
520 can be fit into 877 1 times, resulting in a remainder of 357.
The number 1 becomes the next digit in our result. 
Result so far: 87051.0
If we take 520 away from 877, we end up with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 9:
The number 520 fits into 3570 6 times, leaving a remainder of 450.
The next digit of our result is 6. 
Result so far: 87051.6
The remainder is 450 after subtracting 3120 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 10:
The number 520 fits into 4500 8 times, leaving a remainder of 340.
Write down 8 as next digit of the result. 
Result so far: 87051.68
If we subtract 4160 from 4500, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 11:
When dividing 3400 by 520, we get 6 with a remainder of 280.
The number 6 becomes the next digit in our result. 
Result so far: 87051.686
Subtracting 3120 from 3400 leaves us with 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 12:
520 goes into 2800 5 times with a remainder of 200.
The next digit of our result is 5. 
Result so far: 87051.6865
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.

On to step 13:
The number 520 fits into 2000 3 times, leaving a remainder of 440.
The number 3 becomes the next digit in our result. 
Result so far: 87051.68653
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.

Let's proceed to step 14:
520 can be fit into 4400 8 times, resulting in a remainder of 240.
Put 8 as the next digit of the answer. 
Result so far: 87051.686538
If we subtract 4160 from 4400, we get 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 15:
2400 divided by 520 is 4 with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 87051.6865384
If we take 2080 away from 2400, 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.

Moving on to step 16:
The number 520 fits into 3200 6 times, leaving a remainder of 80.
Record the quotient 6 as the next digit in the result. 
Result so far: 87051.68653846
If we take 3120 away from 3200, we end up 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.

The final outcome is 87051.68653846, with a leftover of 8e-08.
