45979299 ÷ 520 
Our goal is to divide 45979299 by 520.

Let's proceed to step 1:
520 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 520

Moving on to step 2:
45 divided by 520 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 520

Going ahead to step 3:
If we divide 459 by 520, we get 0 and a remainder of 459.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 459 to get 459.
Append the next digit (7) from the dividend to 459 and continue with: 4597 / 520

Step 4:
520 goes into 4597 8 times with a remainder of 437.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 4160 away from 4597, we end up with 437.
Fetch the next digit (9) from the dividend, attach it to 437 and continue: 4379 / 520

On to step 5:
When dividing 4379 by 520, we get 8 with a remainder of 219.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtracting 4160 from 4379 leaves us with 219.
Bring next digit (2) of the dividend behind the 219 and repeat the process: 2192 / 520

Step 6:
If we divide 2192 by 520, we get 4 and a remainder of 112.
The number 4 becomes the next digit in our result. 
Result so far: 884.0
Deduct 2080 from 2192 and we're left with 112.
Include the next digit (9) from the dividend after 112, then repeat: 1129 / 520

Step 7:
The number 520 fits into 1129 2 times, leaving a remainder of 89.
Write down 2 as next digit of the result. 
Result so far: 8842.0
Subtract 1040 from 1129 to get 89.
Append the next digit (9) from the dividend to 89 and continue with: 899 / 520

On to step 8:
When dividing 899 by 520, we get 1 with a remainder of 379.
The next digit of our result is 1. 
Result so far: 88421.0
Subtracting 520 from 899 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Moving on to step 9:
The number 520 fits into 3790 7 times, leaving a remainder of 150.
The next digit of our result is 7. 
Result so far: 88421.7
The remainder is 150 after subtracting 3640 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 10:
520 goes into 1500 2 times with a remainder of 460.
Put 2 as the next digit of the answer. 
Result so far: 88421.72
If we subtract 1040 from 1500, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 11:
4600 divided by 520 is 8 with a remainder of 440.
Put 8 as the next digit of the answer. 
Result so far: 88421.728
If we subtract 4160 from 4600, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 12:
520 goes into 4400 8 times with a remainder of 240.
Write down 8 as next digit of the result. 
Result so far: 88421.7288
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 quotient of the division is 88421.7288, and the remainder is 0.0024.
