Let's divide 722129 by 5
We want to figure out the number of times 722129 can be divided by 5.

Step 1:
5 goes into 7 1 times with 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 (2) from the dividend, attach it to 2 and continue: 22 / 5

Let's proceed to step 2:
When dividing 22 by 5, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 20 from 22 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 5

Advancing to step 3:
If we divide 22 by 5, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 2 after subtracting 20 from 22.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 5

Let's proceed to step 4:
The number 5 fits into 21 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 1444.0
Deduct 20 from 21 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 5

Let's proceed to step 5:
5 can be fit into 12 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 14442.0
Deduct 10 from 12 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 5

Step 6:
When dividing 29 by 5, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 144425.0
Subtracting 25 from 29 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 5 fits into 40 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 144425.8
Subtract 40 from 40 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.

Step 8:
5 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 144425.8
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 9:
5 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 144425.8
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.

The final result is 144425.8 with a remainder of 0.0.
