155949 ÷ 39 
Let's see how many times 39 fits into 155949.

On to step 1:
39 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 39

Step 2:
If we divide 15 by 39, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 39

Advancing to step 3:
155 divided by 39 is 3 with a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 38 after subtracting 117 from 155.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 39

On to step 4:
39 can be fit into 389 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtract 351 from 389 to get 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 39

Step 5:
The number 39 fits into 384 9 times, leaving a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 399.0
Subtracting 351 from 384 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 39

Moving on to step 6:
339 divided by 39 is 8 with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 3998.0
Subtract 312 from 339 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 39 fits into 270 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 3998.6
If we take 234 away from 270, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
39 goes into 360 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 3998.69
Subtracting 351 from 360 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
If we divide 90 by 39, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 3998.692
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
120 divided by 39 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3998.6923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
39 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3998.6923
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
When dividing 300 by 39, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 3998.692307
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
270 divided by 39 is 6 with a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 3998.6923076
The remainder is 36 after subtracting 234 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
If we divide 360 by 39, we get 9 and a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 3998.69230769
The remainder is 9 after subtracting 351 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 3998.69230769 with a balance of 9e-09.
