We look at the division of 641899 by 5 
We're looking to find how many times 5 goes into 641899.

Let's proceed to step 1:
If we divide 6 by 5, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 5 away from 6, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 5

Moving on to step 2:
5 can be fit into 14 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 10 from 14 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 5

Let's proceed to step 3:
When dividing 41 by 5, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 128.0
The remainder is 1 after subtracting 40 from 41.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 5

On to step 4:
When dividing 18 by 5, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1283.0
Subtracting 15 from 18 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 5

On to step 5:
If we divide 39 by 5, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 12837.0
Subtract 35 from 39 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 5

Advancing to step 6:
If we divide 49 by 5, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 128379.0
If we subtract 45 from 49, 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.

On to step 7:
If we divide 40 by 5, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 128379.8
The remainder is 0 after subtracting 40 from 40.
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:
0 divided by 5 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 128379.8
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.

Moving on to step 9:
0 divided by 5 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 128379.8
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.

In conclusion, the division gives 128379.8 with a balance of 0.0.
