We look at the division of 16921519 by 209 
We're looking to find how many times 209 goes into 16921519.

Step 1:
If we divide 1 by 209, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 209

On to step 2:
16 divided by 209 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 209

On to step 3:
If we divide 169 by 209, we get 0 and a remainder of 169.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 169 to get 169.
Fetch the next digit (2) from the dividend, attach it to 169 and continue: 1692 / 209

Let's proceed to step 4:
The number 209 fits into 1692 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 1672 from 1692 to get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 209

On to step 5:
201 divided by 209 is 0 with a remainder of 201.
Write down 0 as next digit of the result. 
Result so far: 80.0
The remainder is 201 after subtracting 0 from 201.
Bring next digit (5) of the dividend behind the 201 and repeat the process: 2015 / 209

Moving on to step 6:
209 can be fit into 2015 9 times, resulting in a remainder of 134.
Write down 9 as next digit of the result. 
Result so far: 809.0
If we subtract 1881 from 2015, we get 134.
Fetch the next digit (1) from the dividend, attach it to 134 and continue: 1341 / 209

Advancing to step 7:
209 goes into 1341 6 times with a remainder of 87.
Use 6 as the next digit of our solution. 
Result so far: 8096.0
The remainder is 87 after subtracting 1254 from 1341.
Append the next digit (9) from the dividend to 87 and continue with: 879 / 209

Step 8:
The number 209 fits into 879 4 times, leaving a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 80964.0
Deduct 836 from 879 and we're left 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.

Advancing to step 9:
If we divide 430 by 209, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 80964.2
Subtracting 418 from 430 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
209 goes into 120 0 times with a remainder of 120.
The next digit of our result is 0. 
Result so far: 80964.2
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
209 can be fit into 1200 5 times, resulting in a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 80964.205
Subtracting 1045 from 1200 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Step 12:
1550 divided by 209 is 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 80964.2057
Subtracting 1463 from 1550 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 13:
When dividing 870 by 209, we get 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 80964.20574
The remainder is 34 after subtracting 836 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
The number 209 fits into 340 1 times, leaving a remainder of 131.
The number 1 becomes the next digit in our result. 
Result so far: 80964.205741
If we subtract 209 from 340, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 15:
If we divide 1310 by 209, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 80964.2057416
If we take 1254 away from 1310, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 16:
When dividing 560 by 209, we get 2 with a remainder of 142.
Write down 2 as next digit of the result. 
Result so far: 80964.20574162
The remainder is 142 after subtracting 418 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 80964.20574162 with a remaining 1.42e-07.
