66794335 ÷ 494 
Our goal is to divide 66794335 by 494.

Step 1:
When dividing 6 by 494, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 494

Going ahead to step 2:
If we divide 66 by 494, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 494

Moving on to step 3:
The number 494 fits into 667 1 times, leaving a remainder of 173.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 494 from 667 to get 173.
Bring next digit (9) of the dividend behind the 173 and repeat the process: 1739 / 494

Step 4:
494 goes into 1739 3 times with a remainder of 257.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1482 away from 1739, we end up with 257.
Include the next digit (4) from the dividend after 257, then repeat: 2574 / 494

Advancing to step 5:
494 goes into 2574 5 times with a remainder of 104.
Put 5 as the next digit of the answer. 
Result so far: 135.0
Deduct 2470 from 2574 and we're left with 104.
Bring next digit (3) of the dividend behind the 104 and repeat the process: 1043 / 494

Let's proceed to step 6:
The number 494 fits into 1043 2 times, leaving a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 1352.0
If we subtract 988 from 1043, we get 55.
Grab the next digit (3) from the dividend, add it to 55, then carry on: 553 / 494

Advancing to step 7:
553 divided by 494 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 13521.0
If we subtract 494 from 553, we get 59.
Grab the next digit (5) from the dividend, add it to 59, then carry on: 595 / 494

Advancing to step 8:
The number 494 fits into 595 1 times, leaving a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 135211.0
Deduct 494 from 595 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
The number 494 fits into 1010 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 135211.2
The remainder is 22 after subtracting 988 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
The number 494 fits into 220 0 times, leaving a remainder of 220.
The next digit of our result is 0. 
Result so far: 135211.2
Subtract 0 from 220 to get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 11:
494 goes into 2200 4 times with a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 135211.204
If we take 1976 away from 2200, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 12:
494 goes into 2240 4 times with a remainder of 264.
Record the quotient 4 as the next digit in the result. 
Result so far: 135211.2044
If we take 1976 away from 2240, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Our division results in 135211.2044 with a remaining 0.00264.
