We look at the division of 19172319 by 209 
We want to figure out the number of times 19172319 can be divided by 209.

Moving on to step 1:
When dividing 1 by 209, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 209

On to step 2:
209 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 209

On to step 3:
If we divide 191 by 209, we get 0 and a remainder of 191.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 191 leaves us with 191.
Include the next digit (7) from the dividend after 191, then repeat: 1917 / 209

Going ahead to step 4:
209 can be fit into 1917 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 1881 from 1917 and we're left with 36.
Append the next digit (2) from the dividend to 36 and continue with: 362 / 209

Advancing to step 5:
209 can be fit into 362 1 times, resulting in a remainder of 153.
Write down 1 as next digit of the result. 
Result so far: 91.0
The remainder is 153 after subtracting 209 from 362.
Fetch the next digit (3) from the dividend, attach it to 153 and continue: 1533 / 209

On to step 6:
When dividing 1533 by 209, we get 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 917.0
Subtract 1463 from 1533 to get 70.
Include the next digit (1) from the dividend after 70, then repeat: 701 / 209

Moving on to step 7:
When dividing 701 by 209, we get 3 with a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 9173.0
Subtracting 627 from 701 leaves us with 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 209

Step 8:
209 can be fit into 749 3 times, resulting in a remainder of 122.
Record the quotient 3 as the next digit in the result. 
Result so far: 91733.0
Subtracting 627 from 749 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 9:
The number 209 fits into 1220 5 times, leaving a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 91733.5
The remainder is 175 after subtracting 1045 from 1220.
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 10:
1750 divided by 209 is 8 with a remainder of 78.
The number 8 becomes the next digit in our result. 
Result so far: 91733.58
Subtract 1672 from 1750 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
If we divide 780 by 209, we get 3 and a remainder of 153.
The next digit of our result is 3. 
Result so far: 91733.583
If we subtract 627 from 780, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 12:
209 goes into 1530 7 times with a remainder of 67.
The next digit of our result is 7. 
Result so far: 91733.5837
If we take 1463 away from 1530, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 13:
If we divide 670 by 209, we get 3 and a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 91733.58373
Subtracting 627 from 670 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 14:
209 can be fit into 430 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 91733.583732
If we subtract 418 from 430, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
209 can be fit into 120 0 times, resulting in a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 91733.583732
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 16:
When dividing 1200 by 209, we get 5 with a remainder of 155.
The next digit of our result is 5. 
Result so far: 91733.58373205
Subtract 1045 from 1200 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Our division results in 91733.58373205 with a remaining 1.55e-07.
