28109297 ÷ 193 
We want to figure out the number of times 28109297 can be divided by 193.

Going ahead to step 1:
The number 193 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 193

Step 2:
28 divided by 193 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 193

On to step 3:
281 divided by 193 is 1 with a remainder of 88.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 193 from 281 leaves us with 88.
Append the next digit (0) from the dividend to 88 and continue with: 880 / 193

Going ahead to step 4:
The number 193 fits into 880 4 times, leaving a remainder of 108.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 772 from 880 and we're left with 108.
Fetch the next digit (9) from the dividend, attach it to 108 and continue: 1089 / 193

Step 5:
If we divide 1089 by 193, we get 5 and a remainder of 124.
The next digit of our result is 5. 
Result so far: 145.0
If we subtract 965 from 1089, we get 124.
Append the next digit (2) from the dividend to 124 and continue with: 1242 / 193

Moving on to step 6:
The number 193 fits into 1242 6 times, leaving a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 1456.0
Subtracting 1158 from 1242 leaves us with 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 193

On to step 7:
When dividing 849 by 193, we get 4 with a remainder of 77.
Record the quotient 4 as the next digit in the result. 
Result so far: 14564.0
Subtract 772 from 849 to get 77.
Append the next digit (7) from the dividend to 77 and continue with: 777 / 193

Step 8:
193 goes into 777 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 145644.0
Subtract 772 from 777 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
50 divided by 193 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 145644.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
If we divide 500 by 193, we get 2 and a remainder of 114.
Record the quotient 2 as the next digit in the result. 
Result so far: 145644.02
If we subtract 386 from 500, we get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 11:
193 can be fit into 1140 5 times, resulting in a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 145644.025
Subtracting 965 from 1140 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 12:
When dividing 1750 by 193, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 145644.0259
The remainder is 13 after subtracting 1737 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
193 goes into 130 0 times with a remainder of 130.
The next digit of our result is 0. 
Result so far: 145644.0259
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 14:
If we divide 1300 by 193, we get 6 and a remainder of 142.
Put 6 as the next digit of the answer. 
Result so far: 145644.025906
If we subtract 1158 from 1300, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 15:
When dividing 1420 by 193, we get 7 with a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 145644.0259067
The remainder is 69 after subtracting 1351 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 16:
The number 193 fits into 690 3 times, leaving a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 145644.02590673
Deduct 579 from 690 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

The final outcome is 145644.02590673, with a leftover of 1.11e-07.
