We look at the division of 663617 by 39 
We want to figure out the number of times 663617 can be divided by 39.

Going ahead to step 1:
When dividing 6 by 39, we get 0 with 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.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 39

Let's proceed to step 2:
39 goes into 66 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 39 from 66 and we're left with 27.
Fetch the next digit (3) from the dividend, attach it to 27 and continue: 273 / 39

Advancing to step 3:
When dividing 273 by 39, we get 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 273 from 273 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 39

Going ahead to step 4:
39 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 170.0
If we subtract 0 from 6, we get 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 39

Going ahead to step 5:
The number 39 fits into 61 1 times, leaving a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1701.0
If we subtract 39 from 61, we get 22.
Grab the next digit (7) from the dividend, add it to 22, then carry on: 227 / 39

On to step 6:
39 can be fit into 227 5 times, resulting in a remainder of 32.
Write down 5 as next digit of the result. 
Result so far: 17015.0
Deduct 195 from 227 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
If we divide 320 by 39, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 17015.8
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
39 goes into 80 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 17015.82
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
39 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 17015.82
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
39 can be fit into 200 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 17015.8205
Subtracting 195 from 200 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
50 divided by 39 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 17015.82051
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
39 goes into 110 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 17015.820512
Subtract 78 from 110 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
The number 39 fits into 320 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 17015.8205128
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
39 goes into 80 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 17015.82051282
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 17015.82051282 with a remainder of 2e-09.
