636377 ÷ 1 
We want to divide 636377 by 1.

On to step 1:
The number 1 fits into 6 6 times, leaving 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.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Going ahead to step 2:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtracting 3 from 3 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Step 3:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 636.0
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Moving on to step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 6363.0
If we subtract 3 from 3, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 5:
If we divide 7 by 1, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 63637.0
The remainder is 0 after subtracting 7 from 7.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Going ahead to step 6:
1 goes into 7 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 636377.0
Subtract 7 from 7 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 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 636377.0
The remainder is 0 after subtracting 0 from 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:
When dividing 0 by 1, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 636377.0
The remainder is 0 after subtracting 0 from 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 636377.0, with a leftover of 0.0.
