66507723 divided by 439 
We want to figure out the number of times 66507723 can be divided by 439.

Advancing to step 1:
The number 439 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 439

Going ahead to step 2:
439 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (5) from the dividend, add it to 66, then carry on: 665 / 439

Going ahead to step 3:
439 can be fit into 665 1 times, resulting in a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 439 from 665 and we're left with 226.
Fetch the next digit (0) from the dividend, attach it to 226 and continue: 2260 / 439

Going ahead to step 4:
When dividing 2260 by 439, we get 5 with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2195 from 2260 to get 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 439

Let's proceed to step 5:
657 divided by 439 is 1 with a remainder of 218.
Use 1 as the next digit of our solution. 
Result so far: 151.0
The remainder is 218 after subtracting 439 from 657.
Take the next digit (7) from the dividend and append it to 218, then repeat: 2187 / 439

Let's proceed to step 6:
439 goes into 2187 4 times with a remainder of 431.
The number 4 becomes the next digit in our result. 
Result so far: 1514.0
Subtract 1756 from 2187 to get 431.
Fetch the next digit (2) from the dividend, attach it to 431 and continue: 4312 / 439

Step 7:
4312 divided by 439 is 9 with a remainder of 361.
The number 9 becomes the next digit in our result. 
Result so far: 15149.0
Deduct 3951 from 4312 and we're left with 361.
Include the next digit (3) from the dividend after 361, then repeat: 3613 / 439

Let's proceed to step 8:
When dividing 3613 by 439, we get 8 with a remainder of 101.
The number 8 becomes the next digit in our result. 
Result so far: 151498.0
If we subtract 3512 from 3613, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
439 can be fit into 1010 2 times, resulting in a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 151498.2
Subtracting 878 from 1010 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 10:
439 goes into 1320 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 151498.23
If we take 1317 away from 1320, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
When dividing 30 by 439, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 151498.23
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
When dividing 300 by 439, we get 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 151498.23
If we subtract 0 from 300, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

After the division, we end up with 151498.23 and a remainder of 0.003.
