Let's divide 830423 by 66
We want to figure out the number of times 830423 can be divided by 66.

Step 1:
If we divide 8 by 66, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 66

Going ahead to step 2:
If we divide 83 by 66, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 66 from 83 leaves us with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 66

Let's proceed to step 3:
If we divide 170 by 66, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 132 from 170 leaves us with 38.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 66

Advancing to step 4:
When dividing 384 by 66, we get 5 with a remainder of 54.
Use 5 as the next digit of our solution. 
Result so far: 125.0
Subtract 330 from 384 to get 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 66

Let's proceed to step 5:
542 divided by 66 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 1258.0
If we take 528 away from 542, we end up with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 66

Step 6:
If we divide 143 by 66, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 12582.0
Deduct 132 from 143 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
When dividing 110 by 66, we get 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 12582.1
Deduct 66 from 110 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
If we divide 440 by 66, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 12582.16
If we take 396 away from 440, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 66, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 12582.166
The remainder is 44 after subtracting 396 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 12582.166, with a leftover of 0.0044.
