19908548 ÷ 520 
We want to divide 19908548 by 520.

Going ahead to step 1:
520 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 520

Step 2:
520 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 520

Let's proceed to step 3:
520 can be fit into 199 0 times, resulting in a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 199 to get 199.
Bring next digit (0) of the dividend behind the 199 and repeat the process: 1990 / 520

Advancing to step 4:
When dividing 1990 by 520, we get 3 with a remainder of 430.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1560 from 1990 to get 430.
Fetch the next digit (8) from the dividend, attach it to 430 and continue: 4308 / 520

Step 5:
The number 520 fits into 4308 8 times, leaving a remainder of 148.
The next digit of our result is 8. 
Result so far: 38.0
Subtracting 4160 from 4308 leaves us with 148.
Grab the next digit (5) from the dividend, add it to 148, then carry on: 1485 / 520

Going ahead to step 6:
520 can be fit into 1485 2 times, resulting in a remainder of 445.
Put 2 as the next digit of the answer. 
Result so far: 382.0
Subtracting 1040 from 1485 leaves us with 445.
Append the next digit (4) from the dividend to 445 and continue with: 4454 / 520

On to step 7:
If we divide 4454 by 520, we get 8 and a remainder of 294.
Record the quotient 8 as the next digit in the result. 
Result so far: 3828.0
If we subtract 4160 from 4454, we get 294.
Include the next digit (8) from the dividend after 294, then repeat: 2948 / 520

Going ahead to step 8:
If we divide 2948 by 520, we get 5 and a remainder of 348.
The number 5 becomes the next digit in our result. 
Result so far: 38285.0
If we subtract 2600 from 2948, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Advancing to step 9:
3480 divided by 520 is 6 with a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 38285.6
If we subtract 3120 from 3480, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 10:
The number 520 fits into 3600 6 times, leaving a remainder of 480.
Put 6 as the next digit of the answer. 
Result so far: 38285.66
If we take 3120 away from 3600, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

The quotient of the division is 38285.66, and the remainder is 0.48.
