We divide 421493 by 5
We're looking to find how many times 5 goes into 421493.

Let's proceed to step 1:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 5

Step 2:
The number 5 fits into 42 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 40 from 42 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 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: 84.0
Subtracting 20 from 21 leaves us with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 5

Moving on to step 4:
5 can be fit into 14 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 842.0
Deduct 10 from 14 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 5

Step 5:
49 divided by 5 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 8429.0
Subtracting 45 from 49 leaves us with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 5

On to step 6:
If we divide 43 by 5, we get 8 and a remainder of 3.
The next digit of our result is 8. 
Result so far: 84298.0
If we take 40 away from 43, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 5, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 84298.6
Deduct 30 from 30 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.

Going ahead to step 8:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 84298.6
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.

Advancing to step 9:
0 divided by 5 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 84298.6
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 quotient of the division is 84298.6, and the remainder is 0.0.
