We're dividing 43675660 by 520 
We want to figure out the number of times 43675660 can be divided by 520.

Advancing to step 1:
If we divide 4 by 520, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 520

Step 2:
520 goes into 43 0 times with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 520

Moving on to step 3:
520 can be fit into 436 0 times, resulting in a remainder of 436.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 436 after subtracting 0 from 436.
Include the next digit (7) from the dividend after 436, then repeat: 4367 / 520

Advancing to step 4:
The number 520 fits into 4367 8 times, leaving a remainder of 207.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 4160 from 4367 to get 207.
Take the next digit (5) from the dividend and append it to 207, then repeat: 2075 / 520

Step 5:
520 goes into 2075 3 times with a remainder of 515.
The next digit of our result is 3. 
Result so far: 83.0
If we subtract 1560 from 2075, we get 515.
Take the next digit (6) from the dividend and append it to 515, then repeat: 5156 / 520

Going ahead to step 6:
The number 520 fits into 5156 9 times, leaving a remainder of 476.
The number 9 becomes the next digit in our result. 
Result so far: 839.0
Subtracting 4680 from 5156 leaves us with 476.
Bring next digit (6) of the dividend behind the 476 and repeat the process: 4766 / 520

Moving on to step 7:
520 can be fit into 4766 9 times, resulting in a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 8399.0
If we subtract 4680 from 4766, we get 86.
Grab the next digit (0) from the dividend, add it to 86, then carry on: 860 / 520

Going ahead to step 8:
520 can be fit into 860 1 times, resulting in a remainder of 340.
The next digit of our result is 1. 
Result so far: 83991.0
Subtract 520 from 860 to 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.

Advancing to step 9:
3400 divided by 520 is 6 with a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 83991.6
Subtract 3120 from 3400 to 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.

On to step 10:
When dividing 2800 by 520, we get 5 with a remainder of 200.
Write down 5 as next digit of the result. 
Result so far: 83991.65
The remainder is 200 after subtracting 2600 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 11:
If we divide 2000 by 520, we get 3 and a remainder of 440.
Write down 3 as next digit of the result. 
Result so far: 83991.653
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.

Going ahead to step 12:
If we divide 4400 by 520, we get 8 and a remainder of 240.
Use 8 as the next digit of our solution. 
Result so far: 83991.6538
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.

Let's proceed to step 13:
2400 divided by 520 is 4 with a remainder of 320.
Write down 4 as next digit of the result. 
Result so far: 83991.65384
Subtracting 2080 from 2400 leaves us 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 14:
520 goes into 3200 6 times with a remainder of 80.
Write down 6 as next digit of the result. 
Result so far: 83991.653846
Subtract 3120 from 3200 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
800 divided by 520 is 1 with a remainder of 280.
Put 1 as the next digit of the answer. 
Result so far: 83991.6538461
The remainder is 280 after subtracting 520 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 16:
The number 520 fits into 2800 5 times, leaving a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 83991.65384615
Subtracting 2600 from 2800 leaves us 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.

The quotient of the division is 83991.65384615, and the remainder is 2e-07.
