Let's divide 63646 by 1
Our goal is to divide 63646 by 1.

Step 1:
1 goes into 6 6 times with 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 (3) of the dividend behind the 0 and repeat the process: 3 / 1

Going ahead to step 2:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Deduct 3 from 3 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Let's proceed to step 3:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 636.0
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 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 6364.0
Subtract 4 from 4 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 1

Step 5:
1 goes into 6 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 63646.0
Subtract 6 from 6 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 6:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 63646.0
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.

Step 7:
0 divided by 1 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 63646.0
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.

The final outcome is 63646.0, with a leftover of 0.0.
