664866 divided by 39 
We want to figure out the number of times 664866 can be divided by 39.

Advancing to step 1:
If we divide 6 by 39, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 39

Advancing to step 2:
39 can be fit into 66 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 39 from 66 and we're left with 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 39

Step 3:
274 divided by 39 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 17.0
Deduct 273 from 274 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 39

Moving on to step 4:
The number 39 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 170.0
If we take 0 away from 18, we end up with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 39

Let's proceed to step 5:
The number 39 fits into 186 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 1704.0
If we subtract 156 from 186, we get 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 39

Moving on to step 6:
39 goes into 306 7 times with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 17047.0
Subtracting 273 from 306 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 17047.8
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 17047.84
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
When dividing 240 by 39, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 17047.846
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
When dividing 60 by 39, we get 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 17047.8461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
39 goes into 210 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 17047.84615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
If we divide 150 by 39, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 17047.846153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 13:
39 goes into 330 8 times with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 17047.8461538
If we take 312 away from 330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
When dividing 180 by 39, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 17047.84615384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 17047.84615384, and the remainder is 2.4e-08.
