Let's divide 153917 by 66
We're looking to find how many times 66 goes into 153917.

Moving on to step 1:
1 divided by 66 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 66

Moving on to step 2:
The number 66 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 66

Step 3:
If we divide 153 by 66, we get 2 and a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 21 after subtracting 132 from 153.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 66

Moving on to step 4:
When dividing 219 by 66, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 198 from 219 and we're left with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 66

On to step 5:
When dividing 211 by 66, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 233.0
The remainder is 13 after subtracting 198 from 211.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 66

On to step 6:
66 goes into 137 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2332.0
The remainder is 5 after subtracting 132 from 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
If we divide 50 by 66, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 2332.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
If we divide 500 by 66, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 2332.07
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2332.075
The remainder is 50 after subtracting 330 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
When dividing 500 by 66, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 2332.0757
Subtracting 462 from 500 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
66 goes into 380 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 2332.07575
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
66 can be fit into 500 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 2332.075757
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
If we divide 380 by 66, we get 5 and a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 2332.0757575
Subtracting 330 from 380 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
If we divide 500 by 66, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 2332.07575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 2332.07575757 with a remainder of 3.8e-08.
