621661 ÷ 19 
We want to divide 621661 by 19.

Going ahead to step 1:
If we divide 6 by 19, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 19

Advancing to step 2:
19 can be fit into 62 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 57 from 62 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 19

Moving on to step 3:
19 can be fit into 51 2 times, resulting in a remainder of 13.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 38 from 51 and we're left with 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 19

Step 4:
19 goes into 136 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 327.0
Subtract 133 from 136 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 19

Advancing to step 5:
When dividing 36 by 19, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 3271.0
If we subtract 19 from 36, we get 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 19

Let's proceed to step 6:
When dividing 171 by 19, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 32719.0
Subtracting 171 from 171 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:
19 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 32719.0
If we take 0 away from 0, 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.

Moving on to step 8:
19 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 32719.0
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.

Our division results in 32719.0 with a remaining 0.0.
