405804 ÷ 43 
Let's see how many times 43 fits into 405804.

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.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 43

Moving on to step 2:
When dividing 40 by 43, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 43

Going ahead to step 3:
When dividing 405 by 43, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 387 from 405, we get 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 43

Moving on to step 4:
If we divide 188 by 43, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 94.0
Subtract 172 from 188 to get 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 43

Step 5:
If we divide 160 by 43, we get 3 and a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 943.0
Subtract 129 from 160 to get 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 43

Advancing to step 6:
When dividing 314 by 43, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 9437.0
If we take 301 away from 314, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
130 divided by 43 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 9437.3
Subtract 129 from 130 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
The number 43 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 9437.3
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 9437.302
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
The number 43 fits into 140 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 9437.3023
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 11:
When dividing 110 by 43, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9437.30232
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
If we divide 240 by 43, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 9437.302325
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 13:
43 can be fit into 250 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 9437.3023255
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.

In conclusion, the division gives 9437.3023255 with a balance of 3.5e-07.
