Let's divide 42397782 by 487
We want to figure out the number of times 42397782 can be divided by 487.

On to step 1:
The number 487 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 487

Advancing to step 2:
The number 487 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 487

Going ahead to step 3:
487 can be fit into 423 0 times, resulting in a remainder of 423.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 423 leaves us with 423.
Grab the next digit (9) from the dividend, add it to 423, then carry on: 4239 / 487

Step 4:
The number 487 fits into 4239 8 times, leaving a remainder of 343.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 343 after subtracting 3896 from 4239.
Append the next digit (7) from the dividend to 343 and continue with: 3437 / 487

Going ahead to step 5:
The number 487 fits into 3437 7 times, leaving a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 3409 from 3437, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 487

Step 6:
487 can be fit into 287 0 times, resulting in a remainder of 287.
Use 0 as the next digit of our solution. 
Result so far: 870.0
The remainder is 287 after subtracting 0 from 287.
Append the next digit (8) from the dividend to 287 and continue with: 2878 / 487

Let's proceed to step 7:
487 goes into 2878 5 times with a remainder of 443.
Use 5 as the next digit of our solution. 
Result so far: 8705.0
Subtracting 2435 from 2878 leaves us with 443.
Append the next digit (2) from the dividend to 443 and continue with: 4432 / 487

Going ahead to step 8:
When dividing 4432 by 487, we get 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 87059.0
Deduct 4383 from 4432 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
The number 487 fits into 490 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 87059.1
Deduct 487 from 490 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 10:
The number 487 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 87059.1
If we subtract 0 from 30, we get 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 11:
If we divide 300 by 487, we get 0 and a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 87059.1
Subtracting 0 from 300 leaves us with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 87059.1 and a remainder of 0.03.
