999378 ÷ 43 
We're looking to find how many times 43 goes into 999378.

Advancing to step 1:
43 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 43

Step 2:
The number 43 fits into 99 2 times, leaving a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 86 away from 99, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 43

Going ahead to step 3:
If we divide 139 by 43, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 10 after subtracting 129 from 139.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 43

Let's proceed to step 4:
43 goes into 103 2 times with a remainder of 17.
The next digit of our result is 2. 
Result so far: 232.0
If we subtract 86 from 103, we get 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 43

Let's proceed to step 5:
When dividing 177 by 43, we get 4 with a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 2324.0
Subtract 172 from 177 to get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 43

Let's proceed to step 6:
When dividing 58 by 43, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 23241.0
If we subtract 43 from 58, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
43 can be fit into 150 3 times, resulting in a remainder of 21.
The next digit of our result is 3. 
Result so far: 23241.3
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
When dividing 210 by 43, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 23241.34
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
380 divided by 43 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 23241.348
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 10:
43 goes into 360 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 23241.3488
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 23241.3488, with a leftover of 0.00016.
