135688 divided by 39 
Let's see how many times 39 fits into 135688.

Going ahead to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 39

Advancing to step 2:
If we divide 13 by 39, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 39

Going ahead to step 3:
If we divide 135 by 39, we get 3 and a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 117 from 135, we get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 39

Step 4:
186 divided by 39 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Deduct 156 from 186 and we're left with 30.
Take the next digit (8) from the dividend and append it to 30, then repeat: 308 / 39

Step 5:
The number 39 fits into 308 7 times, leaving a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 347.0
Subtract 273 from 308 to get 35.
Bring next digit (8) of the dividend behind the 35 and repeat the process: 358 / 39

Going ahead to step 6:
39 can be fit into 358 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 3479.0
Deduct 351 from 358 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
The number 39 fits into 70 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 3479.1
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 8:
When dividing 310 by 39, we get 7 with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 3479.17
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
39 can be fit into 370 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 3479.179
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
The number 39 fits into 190 4 times, leaving a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 3479.1794
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
When dividing 340 by 39, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 3479.17948
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 39 fits into 280 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 3479.179487
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 13:
39 goes into 70 1 times with a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 3479.1794871
Subtracting 39 from 70 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 14:
When dividing 310 by 39, we get 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 3479.17948717
If we subtract 273 from 310, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 3479.17948717 and a remainder of 3.7e-08.
