We're dividing 643727 by 43 
We're looking to find how many times 43 goes into 643727.

Advancing to step 1:
When dividing 6 by 43, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 43

Going ahead to step 2:
When dividing 64 by 43, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 43 from 64 leaves us with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 43

Advancing to step 3:
43 goes into 213 4 times with a remainder of 41.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtracting 172 from 213 leaves us with 41.
Bring next digit (7) of the dividend behind the 41 and repeat the process: 417 / 43

Step 4:
The number 43 fits into 417 9 times, leaving a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 149.0
If we subtract 387 from 417, we get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 43

Advancing to step 5:
43 can be fit into 302 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1497.0
Deduct 301 from 302 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 43

Let's proceed to step 6:
When dividing 17 by 43, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 14970.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
43 can be fit into 170 3 times, resulting in a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 14970.3
The remainder is 41 after subtracting 129 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
The number 43 fits into 410 9 times, leaving a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 14970.39
Subtract 387 from 410 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
43 goes into 230 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 14970.395
Subtracting 215 from 230 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
When dividing 150 by 43, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 14970.3953
Subtracting 129 from 150 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
43 goes into 210 4 times with a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 14970.39534
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
43 goes into 380 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 14970.395348
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
43 goes into 360 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 14970.3953488
If we take 344 away from 360, we end up 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.

Our division results in 14970.3953488 with a remaining 1.6e-07.
