Let's divide 430864 by 40
We want to figure out the number of times 430864 can be divided by 40.

Moving on to step 1:
4 divided by 40 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 40

Moving on to step 2:
If we divide 43 by 40, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 40 from 43 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 40

Moving on to step 3:
40 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (8) from the dividend, add it to 30, then carry on: 308 / 40

Step 4:
The number 40 fits into 308 7 times, leaving a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Deduct 280 from 308 and we're left with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 40

On to step 5:
When dividing 286 by 40, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 1077.0
Subtract 280 from 286 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 40

Going ahead to step 6:
40 can be fit into 64 1 times, resulting in a remainder of 24.
The next digit of our result is 1. 
Result so far: 10771.0
If we subtract 40 from 64, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
240 divided by 40 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 10771.6
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10771.6
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.

Advancing to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10771.6
The remainder is 0 after subtracting 0 from 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 10771.6 with a remaining 0.0.
