169432 ÷ 43 
We want to divide 169432 by 43.

On to step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 43

Going ahead to step 2:
16 divided by 43 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 43

On to step 3:
169 divided by 43 is 3 with a remainder of 40.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 129 from 169 leaves us with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 43

Let's proceed to step 4:
43 goes into 404 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 39.0
Subtract 387 from 404 to get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 43

Advancing to step 5:
43 can be fit into 173 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 394.0
If we take 172 away from 173, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 43

On to step 6:
The number 43 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 3940.0
Subtract 0 from 12 to 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.

Going ahead to step 7:
43 can be fit into 120 2 times, resulting in a remainder of 34.
The next digit of our result is 2. 
Result so far: 3940.2
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
43 goes into 340 7 times with a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 3940.27
Subtract 301 from 340 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
43 can be fit into 390 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3940.279
Deduct 387 from 390 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
30 divided by 43 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3940.279
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
When dividing 300 by 43, we get 6 with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 3940.27906
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
If we divide 420 by 43, we get 9 and a remainder of 33.
The next digit of our result is 9. 
Result so far: 3940.279069
If we take 387 away from 420, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 13:
The number 43 fits into 330 7 times, leaving a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 3940.2790697
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 14:
The number 43 fits into 290 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 3940.27906976
If we take 258 away from 290, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 3940.27906976 and a remainder of 3.2e-08.
