We look at the division of 874543 by 43 
We're looking to find how many times 43 goes into 874543.

Advancing to step 1:
8 divided by 43 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 43

On to step 2:
If we divide 87 by 43, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 86 from 87 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 43

Going ahead to step 3:
14 divided by 43 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 14 and we're left with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 43

Moving on to step 4:
The number 43 fits into 145 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 203.0
If we take 129 away from 145, we end up with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 43

Going ahead to step 5:
The number 43 fits into 164 3 times, leaving a remainder of 35.
The number 3 becomes the next digit in our result. 
Result so far: 2033.0
The remainder is 35 after subtracting 129 from 164.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 43

Let's proceed to step 6:
The number 43 fits into 353 8 times, leaving a remainder of 9.
Put 8 as the next digit of the answer. 
Result so far: 20338.0
If we take 344 away from 353, 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 7:
43 goes into 90 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 20338.2
Deduct 86 from 90 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 43, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 20338.2
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.

Advancing to step 9:
43 goes into 400 9 times with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 20338.209
If we subtract 387 from 400, we 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.

Step 10:
The number 43 fits into 130 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 20338.2093
Subtracting 129 from 130 leaves us 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.

On to step 11:
The number 43 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20338.2093
Subtracting 0 from 10 leaves us 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.

Let's proceed to step 12:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 20338.209302
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
When dividing 140 by 43, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 20338.2093023
Deduct 129 from 140 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
43 can be fit into 110 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 20338.20930232
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 20338.20930232 and a remainder of 2.4e-08.
