Let's divide 501209 by 84
We want to figure out the number of times 501209 can be divided by 84.

Going ahead to step 1:
When dividing 5 by 84, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 84

Going ahead to step 2:
When dividing 50 by 84, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 84

Going ahead to step 3:
84 goes into 501 5 times with a remainder of 81.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 420 from 501, we get 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 84

Let's proceed to step 4:
When dividing 812 by 84, we get 9 with a remainder of 56.
Put 9 as the next digit of the answer. 
Result so far: 59.0
If we subtract 756 from 812, we get 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 84

Advancing to step 5:
84 can be fit into 560 6 times, resulting in a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 596.0
If we subtract 504 from 560, we get 56.
Include the next digit (9) from the dividend after 56, then repeat: 569 / 84

Going ahead to step 6:
If we divide 569 by 84, we get 6 and a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 5966.0
Deduct 504 from 569 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
When dividing 650 by 84, we get 7 with a remainder of 62.
The next digit of our result is 7. 
Result so far: 5966.7
The remainder is 62 after subtracting 588 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
If we divide 620 by 84, we get 7 and a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 5966.77
The remainder is 32 after subtracting 588 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 5966.77, with a leftover of 0.032.
