593421 ÷ 3 
We want to figure out the number of times 593421 can be divided by 3.

Moving on to step 1:
If we divide 5 by 3, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 3 from 5, we get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 3

Step 2:
When dividing 29 by 3, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtract 27 from 29 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 3

Let's proceed to step 3:
The number 3 fits into 23 7 times, leaving a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 197.0
If we take 21 away from 23, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 3

Moving on to step 4:
The number 3 fits into 24 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1978.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

Going ahead to step 5:
2 divided by 3 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 19780.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 3

Advancing to step 6:
3 goes into 21 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 197807.0
If we subtract 21 from 21, 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.

Step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 197807.0
Deduct 0 from 0 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:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 197807.0
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 outcome is 197807.0, with a leftover of 0.0.
