We're dividing 19924465 by 520 
We want to figure out the number of times 19924465 can be divided by 520.

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
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 520

On to step 2:
520 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 520

Moving on to step 3:
199 divided by 520 is 0 with a remainder of 199.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 199, we get 199.
Bring next digit (2) of the dividend behind the 199 and repeat the process: 1992 / 520

Going ahead to step 4:
520 goes into 1992 3 times with a remainder of 432.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1560 away from 1992, we end up with 432.
Grab the next digit (4) from the dividend, add it to 432, then carry on: 4324 / 520

Step 5:
If we divide 4324 by 520, we get 8 and a remainder of 164.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 164 after subtracting 4160 from 4324.
Append the next digit (4) from the dividend to 164 and continue with: 1644 / 520

Let's proceed to step 6:
520 goes into 1644 3 times with a remainder of 84.
Record the quotient 3 as the next digit in the result. 
Result so far: 383.0
Subtracting 1560 from 1644 leaves us with 84.
Fetch the next digit (6) from the dividend, attach it to 84 and continue: 846 / 520

On to step 7:
If we divide 846 by 520, we get 1 and a remainder of 326.
Record the quotient 1 as the next digit in the result. 
Result so far: 3831.0
Subtracting 520 from 846 leaves us with 326.
Take the next digit (5) from the dividend and append it to 326, then repeat: 3265 / 520

Going ahead to step 8:
If we divide 3265 by 520, we get 6 and a remainder of 145.
The next digit of our result is 6. 
Result so far: 38316.0
If we subtract 3120 from 3265, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 9:
1450 divided by 520 is 2 with a remainder of 410.
Use 2 as the next digit of our solution. 
Result so far: 38316.2
Subtracting 1040 from 1450 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 10:
When dividing 4100 by 520, we get 7 with a remainder of 460.
Write down 7 as next digit of the result. 
Result so far: 38316.27
If we subtract 3640 from 4100, 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.

Step 11:
520 goes into 4600 8 times with a remainder of 440.
The next digit of our result is 8. 
Result so far: 38316.278
Deduct 4160 from 4600 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.

Advancing to step 12:
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: 38316.2788
The remainder is 240 after subtracting 4160 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 38316.2788 with a remainder of 0.0024.
