420233 ÷ 40 
We want to figure out the number of times 420233 can be divided by 40.

Step 1:
The number 40 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 40

Moving on to step 2:
When dividing 42 by 40, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 40 from 42 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 40

Moving on to step 3:
The number 40 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 20 to get 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 40

Advancing to step 4:
40 can be fit into 202 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 105.0
The remainder is 2 after subtracting 200 from 202.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 40

Moving on to step 5:
40 goes into 23 0 times with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 1050.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 40

Advancing to step 6:
40 can be fit into 233 5 times, resulting in a remainder of 33.
Use 5 as the next digit of our solution. 
Result so far: 10505.0
If we subtract 200 from 233, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
330 divided by 40 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 10505.8
Subtract 320 from 330 to 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.

Step 8:
100 divided by 40 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 10505.82
Deduct 80 from 100 and we're left 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.

Moving on to step 9:
200 divided by 40 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10505.825
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.

Moving on to step 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10505.825
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 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10505.825
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.

After the division, we end up with 10505.825 and a remainder of 0.0.
