We divide 15122020 by 497
We want to figure out the number of times 15122020 can be divided by 497.

Step 1:
When dividing 1 by 497, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 497

Advancing to step 2:
15 divided by 497 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 497

On to step 3:
If we divide 151 by 497, we get 0 and a remainder of 151.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 151 after subtracting 0 from 151.
Include the next digit (2) from the dividend after 151, then repeat: 1512 / 497

Let's proceed to step 4:
When dividing 1512 by 497, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1491 from 1512, we get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 497

On to step 5:
497 goes into 212 0 times with a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtract 0 from 212 to get 212.
Include the next digit (0) from the dividend after 212, then repeat: 2120 / 497

Going ahead to step 6:
2120 divided by 497 is 4 with a remainder of 132.
The next digit of our result is 4. 
Result so far: 304.0
If we subtract 1988 from 2120, we get 132.
Fetch the next digit (2) from the dividend, attach it to 132 and continue: 1322 / 497

Going ahead to step 7:
When dividing 1322 by 497, we get 2 with a remainder of 328.
Put 2 as the next digit of the answer. 
Result so far: 3042.0
If we subtract 994 from 1322, we get 328.
Bring next digit (0) of the dividend behind the 328 and repeat the process: 3280 / 497

Moving on to step 8:
497 goes into 3280 6 times with a remainder of 298.
The number 6 becomes the next digit in our result. 
Result so far: 30426.0
Deduct 2982 from 3280 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 9:
The number 497 fits into 2980 5 times, leaving a remainder of 495.
Write down 5 as next digit of the result. 
Result so far: 30426.5
If we subtract 2485 from 2980, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Going ahead to step 10:
The number 497 fits into 4950 9 times, leaving a remainder of 477.
Use 9 as the next digit of our solution. 
Result so far: 30426.59
Subtracting 4473 from 4950 leaves us with 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Advancing to step 11:
4770 divided by 497 is 9 with a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 30426.599
If we subtract 4473 from 4770, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

In conclusion, the division gives 30426.599 with a balance of 0.0297.
