We divide 399454 by 43
We want to figure out the number of times 399454 can be divided by 43.

Going ahead to step 1:
43 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 43

Step 2:
43 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 43

Advancing to step 3:
If we divide 399 by 43, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 387 from 399 leaves us with 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 43

Step 4:
43 can be fit into 124 2 times, resulting in a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 92.0
The remainder is 38 after subtracting 86 from 124.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 43

Step 5:
The number 43 fits into 385 8 times, leaving a remainder of 41.
Write down 8 as next digit of the result. 
Result so far: 928.0
Deduct 344 from 385 and we're left with 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 43

On to step 6:
414 divided by 43 is 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 9289.0
If we subtract 387 from 414, we 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.

On to step 7:
43 can be fit into 270 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 9289.6
Subtract 258 from 270 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 43, we get 2 and a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 9289.62
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
When dividing 340 by 43, we get 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 9289.627
The remainder is 39 after subtracting 301 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 10:
390 divided by 43 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9289.6279
The remainder is 3 after subtracting 387 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
If we divide 30 by 43, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9289.6279
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
43 can be fit into 300 6 times, resulting in a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 9289.627906
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 13:
420 divided by 43 is 9 with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 9289.6279069
Subtract 387 from 420 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 14:
If we divide 330 by 43, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 9289.62790697
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 9289.62790697, with a leftover of 2.9e-08.
