Let's divide 621718 by 1
We want to divide 621718 by 1.

Step 1:
If we divide 6 by 1, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 6 from 6 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Let's proceed to step 2:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we take 2 away from 2, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Advancing to step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 621.0
If we take 1 away from 1, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

On to step 4:
When dividing 7 by 1, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 6217.0
If we subtract 7 from 7, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Moving on to step 5:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 62171.0
Subtracting 1 from 1 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

Step 6:
If we divide 8 by 1, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 621718.0
Subtracting 8 from 8 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.

Advancing 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: 621718.0
Subtract 0 from 0 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.

Step 8:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 621718.0
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.

The final result is 621718.0 with a remainder of 0.0.
