43150 divided by 40 
We're looking to find how many times 40 goes into 43150.

On to step 1:
40 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 40

On to step 2:
40 can be fit into 43 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 40 from 43 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 40

Advancing to step 3:
40 can be fit into 31 0 times, resulting in a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 31 after subtracting 0 from 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 40

Advancing to step 4:
40 goes into 315 7 times with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtracting 280 from 315 leaves us with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 40

On to step 5:
40 goes into 350 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 1078.0
The remainder is 30 after subtracting 320 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 6:
When dividing 300 by 40, we get 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 1078.7
Subtract 280 from 300 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1078.75
Subtracting 200 from 200 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1078.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1078.75
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1078.75 with a remaining 0.0.
