Let's divide 43475105 by 520
Our goal is to divide 43475105 by 520.

Advancing to step 1:
520 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 520

Moving on to step 2:
When dividing 43 by 520, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (4) from the dividend, add it to 43, then carry on: 434 / 520

Going ahead to step 3:
434 divided by 520 is 0 with a remainder of 434.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 434, we end up with 434.
Take the next digit (7) from the dividend and append it to 434, then repeat: 4347 / 520

Going ahead to step 4:
The number 520 fits into 4347 8 times, leaving a remainder of 187.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 4160 from 4347 to get 187.
Fetch the next digit (5) from the dividend, attach it to 187 and continue: 1875 / 520

Let's proceed to step 5:
520 goes into 1875 3 times with a remainder of 315.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we take 1560 away from 1875, we end up with 315.
Grab the next digit (1) from the dividend, add it to 315, then carry on: 3151 / 520

Advancing to step 6:
When dividing 3151 by 520, we get 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 836.0
The remainder is 31 after subtracting 3120 from 3151.
Bring next digit (0) of the dividend behind the 31 and repeat the process: 310 / 520

Moving on to step 7:
When dividing 310 by 520, we get 0 with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 8360.0
The remainder is 310 after subtracting 0 from 310.
Include the next digit (5) from the dividend after 310, then repeat: 3105 / 520

Step 8:
3105 divided by 520 is 5 with a remainder of 505.
Use 5 as the next digit of our solution. 
Result so far: 83605.0
If we subtract 2600 from 3105, we get 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 9:
520 can be fit into 5050 9 times, resulting in a remainder of 370.
Record the quotient 9 as the next digit in the result. 
Result so far: 83605.9
Subtract 4680 from 5050 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 10:
When dividing 3700 by 520, we get 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 83605.97
Subtracting 3640 from 3700 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
If we divide 600 by 520, we get 1 and a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 83605.971
If we take 520 away from 600, 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.

Step 12:
If we divide 800 by 520, we get 1 and a remainder of 280.
The next digit of our result is 1. 
Result so far: 83605.9711
Deduct 520 from 800 and we're left 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.

After the division, we end up with 83605.9711 and a remainder of 0.0028.
