We look at the division of 877420 by 1 
Our goal is to divide 877420 by 1.

Let's proceed to step 1:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 8 from 8 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Step 2:
1 goes into 7 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 7 from 7 leaves us with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

Step 3:
1 goes into 7 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 877.0
Deduct 7 from 7 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 4:
If we divide 4 by 1, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 8774.0
Subtract 4 from 4 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Advancing to step 5:
When dividing 2 by 1, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 87742.0
The remainder is 0 after subtracting 2 from 2.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Advancing to step 6:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 877420.0
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.

Let's proceed to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 877420.0
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.

Moving on to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 877420.0
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.

The quotient of the division is 877420.0, and the remainder is 0.0.
