We divide 641395 by 1
We want to figure out the number of times 641395 can be divided by 1.

Let's proceed to step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 2:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we subtract 4 from 4, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Advancing to step 3:
1 goes into 1 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 641.0
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 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 6413.0
Subtract 3 from 3 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

On to step 5:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 64139.0
If we subtract 9 from 9, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

On to step 6:
1 goes into 5 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 641395.0
Deduct 5 from 5 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 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 641395.0
Subtract 0 from 0 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.

Going ahead to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 641395.0
Subtract 0 from 0 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.

After the division, we end up with 641395.0 and a remainder of 0.0.
