637694 ÷ 1 
Our goal is to divide 637694 by 1.

Let's proceed 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
Subtracting 6 from 6 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Going ahead to step 2:
If we divide 3 by 1, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 63.0
The remainder is 0 after subtracting 3 from 3.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Step 3:
1 goes into 7 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 637.0
Subtracting 7 from 7 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Moving on to step 4:
If we divide 6 by 1, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6376.0
If we take 6 away from 6, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 1

On to step 5:
9 divided by 1 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 63769.0
If we subtract 9 from 9, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Let's proceed to step 6:
1 goes into 4 4 times with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 637694.0
If we take 4 away from 4, 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.

On to step 7:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 637694.0
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.

Going ahead 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: 637694.0
If we subtract 0 from 0, we 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 637694.0 with a balance of 0.0.
