664135 divided by 39 
Our goal is to divide 664135 by 39.

Going ahead to step 1:
39 can be fit into 6 0 times, resulting in 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.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 39

Let's proceed to step 2:
If we divide 66 by 39, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 39 from 66 and we're left with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 39

Going ahead to step 3:
When dividing 274 by 39, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 273 from 274 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 39

Advancing to step 4:
39 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtract 0 from 11 to get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 39

Going ahead to step 5:
39 can be fit into 113 2 times, resulting in a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 1702.0
If we subtract 78 from 113, we get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 39

Going ahead to step 6:
39 can be fit into 355 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 17029.0
If we take 351 away from 355, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
If we divide 40 by 39, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 17029.1
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
10 divided by 39 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 17029.1
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
39 goes into 100 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 17029.102
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
220 divided by 39 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 17029.1025
Deduct 195 from 220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
If we divide 250 by 39, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 17029.10256
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 39 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 17029.102564
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
39 goes into 40 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 17029.1025641
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 17029.1025641
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 17029.1025641 with a remainder of 1e-08.
