We look at the division of 662643 by 1 
We want to divide 662643 by 1.

Step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Moving on to step 2:
6 divided by 1 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 66.0
Subtract 6 from 6 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

On to step 3:
1 goes into 2 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 662.0
Subtracting 2 from 2 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Moving on to step 4:
If we divide 6 by 1, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6626.0
Subtract 6 from 6 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Advancing to step 5:
1 goes into 4 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 66264.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

On to step 6:
If we divide 3 by 1, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 662643.0
If we take 3 away from 3, 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.

Let's proceed 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: 662643.0
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.

Moving on to step 8:
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: 662643.0
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.

In conclusion, the division gives 662643.0 with a balance of 0.0.
