We divide 862173 by 66
We want to divide 862173 by 66.

Advancing to step 1:
66 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 66

Step 2:
When dividing 86 by 66, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 20 after subtracting 66 from 86.
Include the next digit (2) from the dividend after 20, then repeat: 202 / 66

Step 3:
The number 66 fits into 202 3 times, leaving a remainder of 4.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 198 from 202 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 66

Step 4:
When dividing 41 by 66, we get 0 with a remainder of 41.
The next digit of our result is 0. 
Result so far: 130.0
The remainder is 41 after subtracting 0 from 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 66

On to step 5:
66 goes into 417 6 times with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 1306.0
Subtracting 396 from 417 leaves us with 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 66

On to step 6:
If we divide 213 by 66, we get 3 and a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 13063.0
Subtract 198 from 213 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
66 goes into 150 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 13063.2
If we subtract 132 from 150, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
66 can be fit into 180 2 times, resulting in a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 13063.22
If we take 132 away from 180, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 13063.22, with a leftover of 0.048.
