We divide 415451 by 43
We want to divide 415451 by 43.

On to step 1:
43 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
If we take 0 away from 4, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 43

Moving on to step 2:
43 can be fit into 41 0 times, resulting in a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 43

Going ahead to step 3:
If we divide 415 by 43, we get 9 and a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 387 from 415 leaves us with 28.
Include the next digit (4) from the dividend after 28, then repeat: 284 / 43

Going ahead to step 4:
If we divide 284 by 43, we get 6 and a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 26 after subtracting 258 from 284.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 43

Advancing to step 5:
43 goes into 265 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 966.0
If we take 258 away from 265, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 43

Going ahead to step 6:
43 can be fit into 71 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 9661.0
Deduct 43 from 71 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
The number 43 fits into 280 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 9661.6
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 43 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 9661.65
The remainder is 5 after subtracting 215 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
50 divided by 43 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 9661.651
Deduct 43 from 50 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
The number 43 fits into 70 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 9661.6511
Subtract 43 from 70 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 9661.6511 and a remainder of 0.00027.
