830370 ÷ 40 
We want to figure out the number of times 830370 can be divided by 40.

Moving on to step 1:
The number 40 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 40

Moving on to step 2:
40 can be fit into 83 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 80 from 83, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 40

Step 3:
If we divide 30 by 40, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 30, we end up with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 40

Step 4:
303 divided by 40 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 207.0
Subtract 280 from 303 to get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 40

Going ahead to step 5:
40 can be fit into 237 5 times, resulting in a remainder of 37.
The next digit of our result is 5. 
Result so far: 2075.0
If we subtract 200 from 237, we get 37.
Bring next digit (0) of the dividend behind the 37 and repeat the process: 370 / 40

Going ahead to step 6:
When dividing 370 by 40, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 20759.0
If we subtract 360 from 370, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 40 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 20759.2
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20759.25
If we subtract 200 from 200, 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.

Step 9:
40 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20759.25
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.

Step 10:
40 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20759.25
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.

In conclusion, the division gives 20759.25 with a balance of 0.0.
