We're dividing 142523 by 66 
Our goal is to divide 142523 by 66.

Moving on to step 1:
66 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 66

Going ahead to step 2:
The number 66 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 66

Step 3:
66 goes into 142 2 times with a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 132 from 142, we get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 66

On to step 4:
66 can be fit into 105 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we subtract 66 from 105, we get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 66

Moving on to step 5:
392 divided by 66 is 5 with a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 215.0
The remainder is 62 after subtracting 330 from 392.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 66

Moving on to step 6:
If we divide 623 by 66, we get 9 and a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 2159.0
Deduct 594 from 623 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
If we divide 290 by 66, we get 4 and a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2159.4
Subtracting 264 from 290 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
260 divided by 66 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 2159.43
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
If we divide 620 by 66, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 2159.439
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
When dividing 260 by 66, we get 3 with a remainder of 62.
The next digit of our result is 3. 
Result so far: 2159.4393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
When dividing 620 by 66, we get 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 2159.43939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 12:
66 can be fit into 260 3 times, resulting in a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 2159.439393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
66 goes into 620 9 times with a remainder of 26.
The next digit of our result is 9. 
Result so far: 2159.4393939
If we take 594 away from 620, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
If we divide 260 by 66, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 2159.43939393
If we subtract 198 from 260, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 2159.43939393 and a remainder of 6.2e-08.
