We're dividing 71369599 by 1 
We're looking to find how many times 1 goes into 71369599.

Moving on to step 1:
7 divided by 1 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 7 from 7 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 2:
When dividing 1 by 1, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 71.0
The remainder is 0 after subtracting 1 from 1.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Let's proceed to step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 713.0
Subtract 3 from 3 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Step 4:
1 goes into 6 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 7136.0
Subtract 6 from 6 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Step 5:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 71369.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

On to step 6:
1 goes into 5 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 713695.0
Deduct 5 from 5 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Going ahead to step 7:
9 divided by 1 is 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 7136959.0
Subtract 9 from 9 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

Let's proceed to step 8:
The number 1 fits into 9 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 71369599.0
If we subtract 9 from 9, we 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.

Let's proceed to step 9:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 71369599.0
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.

Step 10:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 71369599.0
If we take 0 away from 0, we end up 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.

Our division results in 71369599.0 with a remaining 0.0.
