691708 ÷ 39 
We're looking to find how many times 39 goes into 691708.

Step 1:
39 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 39

On to step 2:
39 can be fit into 69 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 39 from 69 leaves us with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 39

On to step 3:
301 divided by 39 is 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Subtracting 273 from 301 leaves us with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 39

On to step 4:
If we divide 287 by 39, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 177.0
If we take 273 away from 287, we end up with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 39

Step 5:
If we divide 140 by 39, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 1773.0
Subtracting 117 from 140 leaves us with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 39

Advancing to step 6:
238 divided by 39 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 17736.0
Subtract 234 from 238 to get 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.
The number 1 becomes the next digit in our result. 
Result so far: 17736.1
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.

On to step 8:
39 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 17736.1
If we subtract 0 from 10, we 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.

Step 9:
100 divided by 39 is 2 with a remainder of 22.
The next digit of our result is 2. 
Result so far: 17736.102
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
39 goes into 220 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 17736.1025
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:
When dividing 250 by 39, we get 6 with a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 17736.10256
Subtracting 234 from 250 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
If we divide 160 by 39, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 17736.102564
Deduct 156 from 160 and we're left 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 13:
The number 39 fits into 40 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 17736.1025641
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.

Step 14:
If we divide 10 by 39, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 17736.1025641
If we take 0 away from 10, we end up 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 17736.1025641 with a remainder of 1e-08.
