We look at the division of 420787 by 10 
Let's see how many times 10 fits into 420787.

On to step 1:
10 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 10

Going ahead to step 2:
When dividing 42 by 10, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 40 from 42 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 10

Moving on to step 3:
10 can be fit into 20 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtracting 20 from 20 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 10

Moving on to step 4:
10 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 420.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 10

Moving on to step 5:
10 goes into 78 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 4207.0
The remainder is 8 after subtracting 70 from 78.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 10

Moving on to step 6:
87 divided by 10 is 8 with a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 42078.0
Deduct 80 from 87 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
70 divided by 10 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 42078.7
Subtract 70 from 70 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.

Moving on to step 8:
10 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42078.7
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.

Let's proceed to step 9:
10 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42078.7
Deduct 0 from 0 and we're left 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.

The quotient of the division is 42078.7, and the remainder is 0.0.
