We divide 639141 by 1
Let's see how many times 1 fits into 639141.

On to step 1:
When dividing 6 by 1, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 6 from 6 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Moving on to step 2:
If we divide 3 by 1, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 3 from 3 to get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 1

Let's proceed to step 3:
1 can be fit into 9 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 639.0
The remainder is 0 after subtracting 9 from 9.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 4:
1 goes into 1 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 6391.0
Subtract 1 from 1 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 5:
1 goes into 4 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 63914.0
Subtract 4 from 4 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Advancing to step 6:
1 goes into 1 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 639141.0
If we take 1 away from 1, 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.

Advancing to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 639141.0
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.

On to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 639141.0
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.

In conclusion, the division gives 639141.0 with a balance of 0.0.
