We look at the division of 66391766 by 350 
Our goal is to divide 66391766 by 350.

Moving on to step 1:
When dividing 6 by 350, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 350

Going ahead to step 2:
350 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (3) of the dividend behind the 66 and repeat the process: 663 / 350

Advancing to step 3:
When dividing 663 by 350, we get 1 with a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 350 from 663 to get 313.
Grab the next digit (9) from the dividend, add it to 313, then carry on: 3139 / 350

Advancing to step 4:
When dividing 3139 by 350, we get 8 with a remainder of 339.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 2800 from 3139, we get 339.
Bring next digit (1) of the dividend behind the 339 and repeat the process: 3391 / 350

On to step 5:
350 can be fit into 3391 9 times, resulting in a remainder of 241.
The next digit of our result is 9. 
Result so far: 189.0
Deduct 3150 from 3391 and we're left with 241.
Append the next digit (7) from the dividend to 241 and continue with: 2417 / 350

Going ahead to step 6:
350 goes into 2417 6 times with a remainder of 317.
Record the quotient 6 as the next digit in the result. 
Result so far: 1896.0
Subtracting 2100 from 2417 leaves us with 317.
Append the next digit (6) from the dividend to 317 and continue with: 3176 / 350

Let's proceed to step 7:
3176 divided by 350 is 9 with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 18969.0
Subtract 3150 from 3176 to get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 350

Advancing to step 8:
When dividing 266 by 350, we get 0 with a remainder of 266.
Record the quotient 0 as the next digit in the result. 
Result so far: 189690.0
Subtracting 0 from 266 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

On to step 9:
The number 350 fits into 2660 7 times, leaving a remainder of 210.
The next digit of our result is 7. 
Result so far: 189690.7
Subtracting 2450 from 2660 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
When dividing 2100 by 350, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 189690.76
If we take 2100 away from 2100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
350 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 189690.76
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
When dividing 0 by 350, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 189690.76
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 189690.76, and the remainder is 0.0.
