17357047 ÷ 520 
Our goal is to divide 17357047 by 520.

Moving on to step 1:
1 divided by 520 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 520

Going ahead to step 2:
The number 520 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 520

On to step 3:
520 goes into 173 0 times with a remainder of 173.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 173 leaves us with 173.
Bring next digit (5) of the dividend behind the 173 and repeat the process: 1735 / 520

Advancing to step 4:
When dividing 1735 by 520, we get 3 with a remainder of 175.
The next digit of our result is 3. 
Result so far: 3.0
If we take 1560 away from 1735, we end up with 175.
Append the next digit (7) from the dividend to 175 and continue with: 1757 / 520

Moving on to step 5:
If we divide 1757 by 520, we get 3 and a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Deduct 1560 from 1757 and we're left with 197.
Grab the next digit (0) from the dividend, add it to 197, then carry on: 1970 / 520

Let's proceed to step 6:
The number 520 fits into 1970 3 times, leaving a remainder of 410.
Write down 3 as next digit of the result. 
Result so far: 333.0
Deduct 1560 from 1970 and we're left with 410.
Append the next digit (4) from the dividend to 410 and continue with: 4104 / 520

Step 7:
520 goes into 4104 7 times with a remainder of 464.
Record the quotient 7 as the next digit in the result. 
Result so far: 3337.0
The remainder is 464 after subtracting 3640 from 4104.
Fetch the next digit (7) from the dividend, attach it to 464 and continue: 4647 / 520

Going ahead to step 8:
520 goes into 4647 8 times with a remainder of 487.
Record the quotient 8 as the next digit in the result. 
Result so far: 33378.0
Subtracting 4160 from 4647 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Let's proceed to step 9:
If we divide 4870 by 520, we get 9 and a remainder of 190.
The next digit of our result is 9. 
Result so far: 33378.9
Subtracting 4680 from 4870 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 10:
520 can be fit into 1900 3 times, resulting in a remainder of 340.
Record the quotient 3 as the next digit in the result. 
Result so far: 33378.93
If we subtract 1560 from 1900, 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.

Advancing to step 11:
520 can be fit into 3400 6 times, resulting in a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 33378.936
Deduct 3120 from 3400 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.

Let's proceed 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: 33378.9365
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.
Put 3 as the next digit of the answer. 
Result so far: 33378.93653
If we subtract 1560 from 2000, 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.

Advancing to step 14:
When dividing 4400 by 520, we get 8 with a remainder of 240.
Record the quotient 8 as the next digit in the result. 
Result so far: 33378.936538
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.

Step 15:
The number 520 fits into 2400 4 times, leaving a remainder of 320.
Record the quotient 4 as the next digit in the result. 
Result so far: 33378.9365384
Deduct 2080 from 2400 and we're left 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.

Step 16:
3200 divided by 520 is 6 with a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 33378.93653846
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.

After the division, we end up with 33378.93653846 and a remainder of 8e-08.
