We look at the division of 16197790 by 255 
We want to figure out the number of times 16197790 can be divided by 255.

Step 1:
255 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 255

Step 2:
The number 255 fits into 16 0 times, leaving 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.
Grab the next digit (1) from the dividend, add it to 16, then carry on: 161 / 255

Going ahead to step 3:
255 goes into 161 0 times with a remainder of 161.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 161 to get 161.
Append the next digit (9) from the dividend to 161 and continue with: 1619 / 255

Moving on to step 4:
The number 255 fits into 1619 6 times, leaving a remainder of 89.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 1530 from 1619 leaves us with 89.
Bring next digit (7) of the dividend behind the 89 and repeat the process: 897 / 255

Let's proceed to step 5:
255 can be fit into 897 3 times, resulting in a remainder of 132.
The next digit of our result is 3. 
Result so far: 63.0
Deduct 765 from 897 and we're left with 132.
Fetch the next digit (7) from the dividend, attach it to 132 and continue: 1327 / 255

Step 6:
The number 255 fits into 1327 5 times, leaving a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 635.0
If we take 1275 away from 1327, we end up with 52.
Include the next digit (9) from the dividend after 52, then repeat: 529 / 255

Step 7:
529 divided by 255 is 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 6352.0
If we subtract 510 from 529, we get 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 255

Let's proceed to step 8:
The number 255 fits into 190 0 times, leaving a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 63520.0
Subtracting 0 from 190 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 9:
255 can be fit into 1900 7 times, resulting in a remainder of 115.
The next digit of our result is 7. 
Result so far: 63520.7
If we take 1785 away from 1900, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 10:
If we divide 1150 by 255, we get 4 and a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 63520.74
Subtracting 1020 from 1150 leaves us with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
255 can be fit into 1300 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 63520.745
The remainder is 25 after subtracting 1275 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
If we divide 250 by 255, we get 0 and a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 63520.745
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 13:
255 goes into 2500 9 times with a remainder of 205.
Use 9 as the next digit of our solution. 
Result so far: 63520.74509
If we subtract 2295 from 2500, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 14:
255 can be fit into 2050 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 63520.745098
Subtracting 2040 from 2050 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 15:
The number 255 fits into 100 0 times, leaving a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 63520.745098
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 16:
255 can be fit into 1000 3 times, resulting in a remainder of 235.
Write down 3 as next digit of the result. 
Result so far: 63520.74509803
Deduct 765 from 1000 and we're left with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final result is 63520.74509803 with a remainder of 2.35e-07.
