Let's divide 66117009 by 353
Our goal is to divide 66117009 by 353.

Advancing to step 1:
The number 353 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 353

Advancing to step 2:
66 divided by 353 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 353

Step 3:
If we divide 661 by 353, we get 1 and a remainder of 308.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 353 from 661 and we're left with 308.
Fetch the next digit (1) from the dividend, attach it to 308 and continue: 3081 / 353

Step 4:
353 can be fit into 3081 8 times, resulting in a remainder of 257.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 2824 from 3081 and we're left with 257.
Take the next digit (7) from the dividend and append it to 257, then repeat: 2577 / 353

Going ahead to step 5:
353 goes into 2577 7 times with a remainder of 106.
Record the quotient 7 as the next digit in the result. 
Result so far: 187.0
Deduct 2471 from 2577 and we're left with 106.
Grab the next digit (0) from the dividend, add it to 106, then carry on: 1060 / 353

On to step 6:
The number 353 fits into 1060 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1873.0
Subtract 1059 from 1060 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 353

Moving on to step 7:
The number 353 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 18730.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 353

On to step 8:
353 goes into 109 0 times with a remainder of 109.
Use 0 as the next digit of our solution. 
Result so far: 187300.0
Subtracting 0 from 109 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 9:
When dividing 1090 by 353, we get 3 with a remainder of 31.
The next digit of our result is 3. 
Result so far: 187300.3
If we take 1059 away from 1090, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 10:
The number 353 fits into 310 0 times, leaving a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 187300.3
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 11:
If we divide 3100 by 353, we get 8 and a remainder of 276.
Put 8 as the next digit of the answer. 
Result so far: 187300.308
Deduct 2824 from 3100 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 12:
If we divide 2760 by 353, we get 7 and a remainder of 289.
Use 7 as the next digit of our solution. 
Result so far: 187300.3087
If we subtract 2471 from 2760, we get 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Going ahead to step 13:
2890 divided by 353 is 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 187300.30878
Subtract 2824 from 2890 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
The number 353 fits into 660 1 times, leaving a remainder of 307.
The next digit of our result is 1. 
Result so far: 187300.308781
Subtract 353 from 660 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 15:
3070 divided by 353 is 8 with a remainder of 246.
Put 8 as the next digit of the answer. 
Result so far: 187300.3087818
If we subtract 2824 from 3070, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 16:
When dividing 2460 by 353, we get 6 with a remainder of 342.
Record the quotient 6 as the next digit in the result. 
Result so far: 187300.30878186
The remainder is 342 after subtracting 2118 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

After the division, we end up with 187300.30878186 and a remainder of 3.42e-07.
