621966 divided by 5 
We want to figure out the number of times 621966 can be divided by 5.

Advancing to step 1:
6 divided by 5 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 5 from 6, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 5

Advancing to step 2:
When dividing 12 by 5, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 10 from 12 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 5

Going ahead to step 3:
If we divide 21 by 5, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 20 from 21 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 5

Moving on to step 4:
5 can be fit into 19 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 1243.0
If we take 15 away from 19, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 5

Advancing to step 5:
5 can be fit into 46 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 12439.0
Subtract 45 from 46 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 5

Going ahead to step 6:
If we divide 16 by 5, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 124393.0
Subtracting 15 from 16 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 5 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 124393.2
Deduct 10 from 10 and we're left 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.

Step 8:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 124393.2
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.

Going ahead to step 9:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 124393.2
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 124393.2 with a remaining 0.0.
