489907 divided by 43 
We want to figure out the number of times 489907 can be divided by 43.

Step 1:
43 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 43

Advancing to step 2:
43 goes into 48 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 43 from 48 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 43

Moving on to step 3:
The number 43 fits into 59 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 43 from 59 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 43

Let's proceed to step 4:
When dividing 169 by 43, we get 3 with a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
The remainder is 40 after subtracting 129 from 169.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 43

On to step 5:
If we divide 400 by 43, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 1139.0
Subtracting 387 from 400 leaves us with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 43

Going ahead to step 6:
The number 43 fits into 137 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 11393.0
If we take 129 away from 137, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
The number 43 fits into 80 1 times, leaving a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 11393.1
If we subtract 43 from 80, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
43 can be fit into 370 8 times, resulting in a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 11393.18
Subtracting 344 from 370 leaves us with 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 9:
When dividing 260 by 43, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 11393.186
If we take 258 away from 260, we end up 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.

On to step 10:
43 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11393.186
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
When dividing 200 by 43, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 11393.18604
If we take 172 away from 200, we end up 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 12:
When dividing 280 by 43, we get 6 with a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 11393.186046
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.

On to step 13:
43 can be fit into 220 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11393.1860465
If we take 215 away from 220, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
43 goes into 50 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 11393.18604651
Subtracting 43 from 50 leaves us 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.

The final outcome is 11393.18604651, with a leftover of 7e-09.
