43856867 ÷ 671 
Let's see how many times 671 fits into 43856867.

Step 1:
The number 671 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 671

Step 2:
671 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 671

Let's proceed to step 3:
438 divided by 671 is 0 with a remainder of 438.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 438, we get 438.
Take the next digit (5) from the dividend and append it to 438, then repeat: 4385 / 671

Let's proceed to step 4:
The number 671 fits into 4385 6 times, leaving a remainder of 359.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 4026 from 4385 to get 359.
Take the next digit (6) from the dividend and append it to 359, then repeat: 3596 / 671

Moving on to step 5:
The number 671 fits into 3596 5 times, leaving a remainder of 241.
Write down 5 as next digit of the result. 
Result so far: 65.0
The remainder is 241 after subtracting 3355 from 3596.
Include the next digit (8) from the dividend after 241, then repeat: 2418 / 671

Let's proceed to step 6:
671 can be fit into 2418 3 times, resulting in a remainder of 405.
Write down 3 as next digit of the result. 
Result so far: 653.0
If we take 2013 away from 2418, we end up with 405.
Append the next digit (6) from the dividend to 405 and continue with: 4056 / 671

Advancing to step 7:
671 can be fit into 4056 6 times, resulting in a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 6536.0
The remainder is 30 after subtracting 4026 from 4056.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 671

Moving on to step 8:
The number 671 fits into 307 0 times, leaving a remainder of 307.
Use 0 as the next digit of our solution. 
Result so far: 65360.0
The remainder is 307 after subtracting 0 from 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

On to step 9:
671 can be fit into 3070 4 times, resulting in a remainder of 386.
The number 4 becomes the next digit in our result. 
Result so far: 65360.4
Subtract 2684 from 3070 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

On to step 10:
671 goes into 3860 5 times with a remainder of 505.
The next digit of our result is 5. 
Result so far: 65360.45
Subtracting 3355 from 3860 leaves us with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Step 11:
If we divide 5050 by 671, we get 7 and a remainder of 353.
Use 7 as the next digit of our solution. 
Result so far: 65360.457
If we take 4697 away from 5050, we end up with 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 12:
671 can be fit into 3530 5 times, resulting in a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 65360.4575
Subtract 3355 from 3530 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 13:
671 goes into 1750 2 times with a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 65360.45752
If we take 1342 away from 1750, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 14:
If we divide 4080 by 671, we get 6 and a remainder of 54.
The next digit of our result is 6. 
Result so far: 65360.457526
If we take 4026 away from 4080, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 15:
If we divide 540 by 671, we get 0 and a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 65360.457526
Subtracting 0 from 540 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 16:
671 goes into 5400 8 times with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 65360.45752608
Subtracting 5368 from 5400 leaves us 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.

The final result is 65360.45752608 with a remainder of 3.2e-08.
