We look at the division of 18971059 by 1 
Let's see how many times 1 fits into 18971059.

Let's proceed to step 1:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 1 from 1, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Let's proceed to step 2:
1 goes into 8 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 8 from 8 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Going ahead to step 3:
1 can be fit into 9 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 189.0
Deduct 9 from 9 and we're left with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Moving on to step 4:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 1897.0
Deduct 7 from 7 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Going ahead to step 5:
1 goes into 1 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 18971.0
Deduct 1 from 1 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Let's proceed to step 6:
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: 189710.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

On to step 7:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1897105.0
If we take 5 away from 5, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 1

Advancing to step 8:
9 divided by 1 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 18971059.0
Deduct 9 from 9 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.

Advancing to step 9:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18971059.0
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.

Step 10:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18971059.0
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.

The final result is 18971059.0 with a remainder of 0.0.
