43219 divided by 40 
Our goal is to divide 43219 by 40.

On to step 1:
When dividing 4 by 40, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 40

On to step 2:
40 goes into 43 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 3 after subtracting 40 from 43.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 40

On to step 3:
When dividing 32 by 40, we get 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 32 to get 32.
Fetch the next digit (1) from the dividend, attach it to 32 and continue: 321 / 40

Let's proceed to step 4:
The number 40 fits into 321 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we take 320 away from 321, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 40

On to step 5:
If we divide 19 by 40, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 1080.0
Subtracting 0 from 19 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 6:
The number 40 fits into 190 4 times, leaving a remainder of 30.
Write down 4 as next digit of the result. 
Result so far: 1080.4
If we take 160 away from 190, we end up 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.

Going ahead to step 7:
40 can be fit into 300 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 1080.47
Subtracting 280 from 300 leaves us with 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 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 1080.475
Subtract 200 from 200 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.

Advancing to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1080.475
If we subtract 0 from 0, we 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.

Advancing to step 10:
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: 1080.475
Deduct 0 from 0 and we're left 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.

After the division, we end up with 1080.475 and a remainder of 0.0.
