We look at the division of 638472 by 1 
We want to figure out the number of times 638472 can be divided by 1.

Advancing to step 1:
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: 6.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 1

Going ahead to step 2:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 3 from 3, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

On to step 3:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 638.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Moving on to step 4:
If we divide 4 by 1, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 6384.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Step 5:
7 divided by 1 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 63847.0
Subtract 7 from 7 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Moving on to step 6:
2 divided by 1 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 638472.0
The remainder is 0 after subtracting 2 from 2.
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 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 638472.0
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:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 638472.0
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 quotient of the division is 638472.0, and the remainder is 0.0.
