We look at the division of 997870 by 1 
We're looking to find how many times 1 goes into 997870.

Let's proceed to step 1:
If we divide 9 by 1, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 9 from 9 to get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Advancing to step 2:
When dividing 9 by 1, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 99.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Moving on to step 3:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 997.0
The remainder is 0 after subtracting 7 from 7.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 4:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 9978.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Moving on to step 5:
7 divided by 1 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 99787.0
Deduct 7 from 7 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Moving on to step 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 997870.0
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.

Moving on to step 7:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 997870.0
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.

Going ahead to step 8:
1 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 997870.0
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.

After the division, we end up with 997870.0 and a remainder of 0.0.
