155142 divided by 66 
Let's see how many times 66 fits into 155142.

Let's proceed to step 1:
66 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 66

Moving on to step 2:
66 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 66

Let's proceed to step 3:
155 divided by 66 is 2 with a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 132 away from 155, we end up with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 66

Going ahead to step 4:
231 divided by 66 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 198 from 231 to get 33.
Take the next digit (4) from the dividend and append it to 33, then repeat: 334 / 66

Advancing to step 5:
66 goes into 334 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Subtracting 330 from 334 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 66

On to step 6:
66 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 2350.0
Subtract 0 from 42 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.

Advancing to step 7:
420 divided by 66 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 2350.6
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 8:
66 goes into 240 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 2350.63
Subtracting 198 from 240 leaves us 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.

On to step 9:
66 can be fit into 420 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2350.636
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.

Moving on to step 10:
240 divided by 66 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 2350.6363
If we take 198 away from 240, we end up 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:
66 goes into 420 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 2350.63636
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.

On to step 12:
If we divide 240 by 66, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 2350.636363
If we take 198 away from 240, we end up 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.

Let's proceed to step 13:
If we divide 420 by 66, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 2350.6363636
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.

Step 14:
66 can be fit into 240 3 times, resulting in a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 2350.63636363
If we take 198 away from 240, we end up 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.

The final outcome is 2350.63636363, with a leftover of 4.2e-08.
