We're dividing 77225589 by 5 
Let's see how many times 5 fits into 77225589.

Step 1:
The number 5 fits into 7 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 5 from 7 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 5

On to step 2:
The number 5 fits into 27 5 times, leaving a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 25 from 27 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 5

Moving on to step 3:
If we divide 22 by 5, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
If we take 20 away from 22, we end up with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 5

On to step 4:
5 goes into 22 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1544.0
Subtracting 20 from 22 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 5

Let's proceed to step 5:
When dividing 25 by 5, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15445.0
The remainder is 0 after subtracting 25 from 25.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 5

Moving on to step 6:
5 can be fit into 5 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 154451.0
The remainder is 0 after subtracting 5 from 5.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 5

On to step 7:
If we divide 8 by 5, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1544511.0
Subtracting 5 from 8 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 5

On to step 8:
39 divided by 5 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 15445117.0
If we subtract 35 from 39, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
5 can be fit into 40 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 15445117.8
Deduct 40 from 40 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 10:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15445117.8
If we subtract 0 from 0, 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.

On to step 11:
0 divided by 5 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15445117.8
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 final outcome is 15445117.8, with a leftover of 0.0.
