We divide 451440 by 43
Let's see how many times 43 fits into 451440.

Moving on to step 1:
43 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 43

Step 2:
The number 43 fits into 45 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 43 from 45.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 43

Moving on to step 3:
43 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 21 to get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 43

Going ahead to step 4:
214 divided by 43 is 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtracting 172 from 214 leaves us with 42.
Grab the next digit (4) from the dividend, add it to 42, then carry on: 424 / 43

Advancing to step 5:
43 goes into 424 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 1049.0
Deduct 387 from 424 and we're left with 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 43

On to step 6:
When dividing 370 by 43, we get 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 10498.0
If we subtract 344 from 370, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
If we divide 260 by 43, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 10498.6
Subtracting 258 from 260 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
43 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10498.6
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
43 goes into 200 4 times with a remainder of 28.
The next digit of our result is 4. 
Result so far: 10498.604
The remainder is 28 after subtracting 172 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
If we divide 280 by 43, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 10498.6046
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 10498.60465
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 12:
If we divide 50 by 43, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 10498.604651
The remainder is 7 after subtracting 43 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 13:
43 can be fit into 70 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 10498.6046511
Deduct 43 from 70 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 10498.6046511, with a leftover of 2.7e-07.
