We look at the division of 66935899 by 353 
Our goal is to divide 66935899 by 353.

On to step 1:
6 divided by 353 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 353

Moving on to step 2:
353 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 353

Step 3:
When dividing 669 by 353, we get 1 with a remainder of 316.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 353 from 669 leaves us with 316.
Bring next digit (3) of the dividend behind the 316 and repeat the process: 3163 / 353

Moving on to step 4:
When dividing 3163 by 353, we get 8 with a remainder of 339.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 2824 from 3163 leaves us with 339.
Fetch the next digit (5) from the dividend, attach it to 339 and continue: 3395 / 353

Advancing to step 5:
3395 divided by 353 is 9 with a remainder of 218.
Put 9 as the next digit of the answer. 
Result so far: 189.0
Subtract 3177 from 3395 to get 218.
Include the next digit (8) from the dividend after 218, then repeat: 2188 / 353

On to step 6:
If we divide 2188 by 353, we get 6 and a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 1896.0
Subtract 2118 from 2188 to get 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 353

On to step 7:
709 divided by 353 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 18962.0
If we take 706 away from 709, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 353

Step 8:
If we divide 39 by 353, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 189620.0
Subtract 0 from 39 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 9:
353 can be fit into 390 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 189620.1
Deduct 353 from 390 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 10:
If we divide 370 by 353, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 189620.11
If we take 353 away from 370, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 189620.11 and a remainder of 0.017.
