665203 ÷ 43 
We want to figure out the number of times 665203 can be divided by 43.

Moving on to step 1:
When dividing 6 by 43, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 43

Let's proceed to step 2:
66 divided by 43 is 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 43 from 66 leaves us with 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 43

On to step 3:
The number 43 fits into 235 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 215 from 235 to get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 43

Step 4:
The number 43 fits into 202 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 154.0
The remainder is 30 after subtracting 172 from 202.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 43

Step 5:
The number 43 fits into 300 6 times, leaving a remainder of 42.
Use 6 as the next digit of our solution. 
Result so far: 1546.0
Subtract 258 from 300 to get 42.
Fetch the next digit (3) from the dividend, attach it to 42 and continue: 423 / 43

Moving on to step 6:
43 can be fit into 423 9 times, resulting in a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 15469.0
The remainder is 36 after subtracting 387 from 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 15469.8
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
160 divided by 43 is 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 15469.83
Subtract 129 from 160 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
When dividing 310 by 43, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 15469.837
If we take 301 away from 310, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
When dividing 90 by 43, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 15469.8372
If we subtract 86 from 90, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 15469.8372
Subtracting 0 from 40 leaves us 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.

Let's proceed to step 12:
43 goes into 400 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 15469.837209
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
130 divided by 43 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 15469.8372093
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
43 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15469.8372093
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 15469.8372093 and a remainder of 1e-08.
