We're dividing 17790164 by 209 
We want to figure out the number of times 17790164 can be divided by 209.

Step 1:
209 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 209

Going ahead to step 2:
209 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 209

Going ahead to step 3:
If we divide 177 by 209, we get 0 and a remainder of 177.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 177, we get 177.
Fetch the next digit (9) from the dividend, attach it to 177 and continue: 1779 / 209

Going ahead to step 4:
209 can be fit into 1779 8 times, resulting in a remainder of 107.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 1672 from 1779 leaves us with 107.
Take the next digit (0) from the dividend and append it to 107, then repeat: 1070 / 209

On to step 5:
The number 209 fits into 1070 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 1045 from 1070 to get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 209

Moving on to step 6:
When dividing 251 by 209, we get 1 with a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 851.0
If we subtract 209 from 251, we get 42.
Fetch the next digit (6) from the dividend, attach it to 42 and continue: 426 / 209

Moving on to step 7:
The number 209 fits into 426 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 8512.0
Subtract 418 from 426 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 209

Moving on to step 8:
The number 209 fits into 84 0 times, leaving a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 85120.0
If we subtract 0 from 84, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 9:
209 can be fit into 840 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 85120.4
The remainder is 4 after subtracting 836 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 209, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 85120.4
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
If we divide 400 by 209, we get 1 and a remainder of 191.
Record the quotient 1 as the next digit in the result. 
Result so far: 85120.401
Subtracting 209 from 400 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 12:
209 goes into 1910 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 85120.4019
The remainder is 29 after subtracting 1881 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 13:
209 goes into 290 1 times with a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 85120.40191
The remainder is 81 after subtracting 209 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 14:
If we divide 810 by 209, we get 3 and a remainder of 183.
Write down 3 as next digit of the result. 
Result so far: 85120.401913
Subtract 627 from 810 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 15:
209 goes into 1830 8 times with a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 85120.4019138
Subtract 1672 from 1830 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 16:
209 goes into 1580 7 times with a remainder of 117.
Record the quotient 7 as the next digit in the result. 
Result so far: 85120.40191387
The remainder is 117 after subtracting 1463 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

The final result is 85120.40191387 with a remainder of 1.17e-07.
