169809 divided by 43 
We want to figure out the number of times 169809 can be divided by 43.

Advancing to step 1:
43 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 43

Advancing to step 2:
43 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 43

Advancing to step 3:
43 goes into 169 3 times with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 40 after subtracting 129 from 169.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 43

Moving on to step 4:
The number 43 fits into 408 9 times, leaving a remainder of 21.
The next digit of our result is 9. 
Result so far: 39.0
Deduct 387 from 408 and we're left with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 43

Step 5:
When dividing 210 by 43, we get 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 394.0
If we take 172 away from 210, we end up with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 43

Step 6:
If we divide 389 by 43, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 3949.0
If we subtract 387 from 389, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
If we divide 20 by 43, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3949.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
If we divide 200 by 43, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 3949.04
Deduct 172 from 200 and we're left 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.

Step 9:
43 goes into 280 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 3949.046
If we subtract 258 from 280, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
The number 43 fits into 220 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3949.0465
Subtract 215 from 220 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 11:
When dividing 50 by 43, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 3949.04651
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 12:
When dividing 70 by 43, we get 1 with a remainder of 27.
Record the quotient 1 as the next digit in the result. 
Result so far: 3949.046511
If we subtract 43 from 70, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 3949.046511 with a remaining 2.7e-06.
