Let's divide 428801 by 40
We want to figure out the number of times 428801 can be divided by 40.

Step 1:
4 divided by 40 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 40

Step 2:
40 goes into 42 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 40 from 42 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 40

Advancing to step 3:
The number 40 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 40

Moving on to step 4:
The number 40 fits into 288 7 times, leaving a remainder of 8.
The next digit of our result is 7. 
Result so far: 107.0
If we subtract 280 from 288, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 40

Step 5:
When dividing 80 by 40, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1072.0
The remainder is 0 after subtracting 80 from 80.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 40

Moving on to step 6:
When dividing 1 by 40, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 10720.0
The remainder is 1 after subtracting 0 from 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 40 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 10720.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 40 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 10720.02
If we take 80 away from 100, we end up 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.
Put 5 as the next digit of the answer. 
Result so far: 10720.025
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.

On to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10720.025
If we take 0 away from 0, we end up 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 11:
0 divided by 40 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10720.025
If we take 0 away from 0, we end up 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 10720.025 and a remainder of 0.0.
