43814274 ÷ 643 
Let's see how many times 643 fits into 43814274.

Step 1:
643 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 643

Step 2:
43 divided by 643 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 643

Moving on to step 3:
438 divided by 643 is 0 with a remainder of 438.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 438 to get 438.
Append the next digit (1) from the dividend to 438 and continue with: 4381 / 643

Going ahead to step 4:
If we divide 4381 by 643, we get 6 and a remainder of 523.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 523 after subtracting 3858 from 4381.
Fetch the next digit (4) from the dividend, attach it to 523 and continue: 5234 / 643

Going ahead to step 5:
If we divide 5234 by 643, we get 8 and a remainder of 90.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 5144 from 5234 and we're left with 90.
Grab the next digit (2) from the dividend, add it to 90, then carry on: 902 / 643

Going ahead to step 6:
643 goes into 902 1 times with a remainder of 259.
Use 1 as the next digit of our solution. 
Result so far: 681.0
Subtracting 643 from 902 leaves us with 259.
Include the next digit (7) from the dividend after 259, then repeat: 2597 / 643

On to step 7:
643 goes into 2597 4 times with a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 6814.0
Deduct 2572 from 2597 and we're left with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 643

Step 8:
The number 643 fits into 254 0 times, leaving a remainder of 254.
Use 0 as the next digit of our solution. 
Result so far: 68140.0
The remainder is 254 after subtracting 0 from 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 9:
643 goes into 2540 3 times with a remainder of 611.
The number 3 becomes the next digit in our result. 
Result so far: 68140.3
The remainder is 611 after subtracting 1929 from 2540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

On to step 10:
The number 643 fits into 6110 9 times, leaving a remainder of 323.
Use 9 as the next digit of our solution. 
Result so far: 68140.39
If we subtract 5787 from 6110, we get 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Step 11:
When dividing 3230 by 643, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 68140.395
If we take 3215 away from 3230, we end up 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.

Let's proceed to step 12:
When dividing 150 by 643, we get 0 with a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 68140.395
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 13:
If we divide 1500 by 643, we get 2 and a remainder of 214.
Put 2 as the next digit of the answer. 
Result so far: 68140.39502
Deduct 1286 from 1500 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 14:
When dividing 2140 by 643, we get 3 with a remainder of 211.
Put 3 as the next digit of the answer. 
Result so far: 68140.395023
Subtracting 1929 from 2140 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Moving on to step 15:
When dividing 2110 by 643, we get 3 with a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 68140.3950233
The remainder is 181 after subtracting 1929 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

The quotient of the division is 68140.3950233, and the remainder is 1.81e-06.
