We're dividing 456900 by 43 
Let's see how many times 43 fits into 456900.

Advancing to step 1:
When dividing 4 by 43, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 43

Step 2:
43 can be fit into 45 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 43 from 45 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 43

Moving on to step 3:
If we divide 26 by 43, we get 0 and a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 43

Step 4:
43 goes into 269 6 times with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 258 from 269 and we're left with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 43

On to step 5:
The number 43 fits into 110 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 1062.0
Subtracting 86 from 110 leaves us with 24.
Bring next digit (0) of the dividend behind the 24 and repeat the process: 240 / 43

On to step 6:
If we divide 240 by 43, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 10625.0
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
The number 43 fits into 250 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 10625.5
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
If we divide 350 by 43, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 10625.58
If we subtract 344 from 350, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
43 goes into 60 1 times with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 10625.581
If we take 43 away from 60, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
If we divide 170 by 43, we get 3 and a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 10625.5813
If we take 129 away from 170, we end up with 41.
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 11:
43 goes into 410 9 times with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 10625.58139
Deduct 387 from 410 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
230 divided by 43 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 10625.581395
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.

Moving on to step 13:
43 goes into 150 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 10625.5813953
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
43 can be fit into 210 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 10625.58139534
The remainder is 38 after subtracting 172 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 10625.58139534, with a leftover of 3.8e-08.
