123495 ÷ 66 
Our goal is to divide 123495 by 66.

Going ahead to step 1:
When dividing 1 by 66, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 66

Step 2:
12 divided by 66 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 66

Advancing to step 3:
66 goes into 123 1 times with a remainder of 57.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 66 away from 123, we end up with 57.
Include the next digit (4) from the dividend after 57, then repeat: 574 / 66

Moving on to step 4:
When dividing 574 by 66, we get 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 528 from 574 and we're left with 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 66

Going ahead to step 5:
66 can be fit into 469 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 187.0
Subtract 462 from 469 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 66

Moving on to step 6:
66 goes into 75 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1871.0
The remainder is 9 after subtracting 66 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 66 fits into 90 1 times, leaving a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1871.1
If we take 66 away from 90, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 8:
240 divided by 66 is 3 with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 1871.13
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 9:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1871.136
Subtract 396 from 420 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
If we divide 240 by 66, we get 3 and a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1871.1363
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
420 divided by 66 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1871.13636
If we subtract 396 from 420, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
66 goes into 240 3 times with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 1871.136363
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
420 divided by 66 is 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 1871.1363636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
66 goes into 240 3 times with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 1871.13636363
Subtract 198 from 240 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 1871.13636363 and a remainder of 4.2e-08.
