169509 ÷ 79 
We're looking to find how many times 79 goes into 169509.

On to step 1:
79 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 79

Advancing to step 2:
If we divide 16 by 79, we get 0 and a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 79

On to step 3:
If we divide 169 by 79, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 158 from 169 leaves us with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 79

Let's proceed to step 4:
79 can be fit into 115 1 times, resulting in a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 79 from 115 and we're left with 36.
Fetch the next digit (0) from the dividend, attach it to 36 and continue: 360 / 79

Moving on to step 5:
The number 79 fits into 360 4 times, leaving a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 214.0
Deduct 316 from 360 and we're left with 44.
Append the next digit (9) from the dividend to 44 and continue with: 449 / 79

On to step 6:
79 goes into 449 5 times with a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 2145.0
Deduct 395 from 449 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
540 divided by 79 is 6 with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 2145.6
Subtract 474 from 540 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
79 goes into 660 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 2145.68
If we take 632 away from 660, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
79 can be fit into 280 3 times, resulting in a remainder of 43.
The next digit of our result is 3. 
Result so far: 2145.683
Deduct 237 from 280 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 10:
79 can be fit into 430 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2145.6835
If we take 395 away from 430, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
350 divided by 79 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 2145.68354
The remainder is 34 after subtracting 316 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
79 goes into 340 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 2145.683544
Subtract 316 from 340 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 2145.683544 with a remainder of 2.4e-06.
