621948 divided by 1 
Our goal is to divide 621948 by 1.

Advancing to 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
Subtract 6 from 6 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Advancing to step 2:
2 divided by 1 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 62.0
The remainder is 0 after subtracting 2 from 2.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Going ahead to step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 621.0
If we subtract 1 from 1, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 1

Step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 6219.0
Deduct 9 from 9 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Advancing to step 5:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 62194.0
If we subtract 4 from 4, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Step 6:
8 divided by 1 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 621948.0
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.

Moving on to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 621948.0
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.

Let's proceed to step 8:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 621948.0
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.

After the division, we end up with 621948.0 and a remainder of 0.0.
