16572974 ÷ 579 
We want to figure out the number of times 16572974 can be divided by 579.

On to step 1:
1 divided by 579 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 579

Step 2:
If we divide 16 by 579, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 579

Let's proceed to step 3:
579 can be fit into 165 0 times, resulting in a remainder of 165.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 165, we get 165.
Take the next digit (7) from the dividend and append it to 165, then repeat: 1657 / 579

Advancing to step 4:
The number 579 fits into 1657 2 times, leaving a remainder of 499.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1158 from 1657, we get 499.
Include the next digit (2) from the dividend after 499, then repeat: 4992 / 579

Let's proceed to step 5:
579 goes into 4992 8 times with a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 360 after subtracting 4632 from 4992.
Append the next digit (9) from the dividend to 360 and continue with: 3609 / 579

Going ahead to step 6:
If we divide 3609 by 579, we get 6 and a remainder of 135.
Record the quotient 6 as the next digit in the result. 
Result so far: 286.0
Subtracting 3474 from 3609 leaves us with 135.
Include the next digit (7) from the dividend after 135, then repeat: 1357 / 579

Going ahead to step 7:
If we divide 1357 by 579, we get 2 and a remainder of 199.
Record the quotient 2 as the next digit in the result. 
Result so far: 2862.0
The remainder is 199 after subtracting 1158 from 1357.
Grab the next digit (4) from the dividend, add it to 199, then carry on: 1994 / 579

On to step 8:
If we divide 1994 by 579, we get 3 and a remainder of 257.
Write down 3 as next digit of the result. 
Result so far: 28623.0
If we subtract 1737 from 1994, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 9:
The number 579 fits into 2570 4 times, leaving a remainder of 254.
The next digit of our result is 4. 
Result so far: 28623.4
If we take 2316 away from 2570, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 10:
When dividing 2540 by 579, we get 4 with a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 28623.44
Subtract 2316 from 2540 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 28623.44 with a remainder of 0.224.
