155081 ÷ 39 
Let's see how many times 39 fits into 155081.

Moving on 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
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 39

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

Advancing to step 3:
The number 39 fits into 155 3 times, leaving a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 117 from 155, we get 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 39

On to step 4:
The number 39 fits into 380 9 times, leaving a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 351 away from 380, we end up with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 39

Let's proceed to step 5:
If we divide 298 by 39, we get 7 and a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
The remainder is 25 after subtracting 273 from 298.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 39

Advancing to step 6:
When dividing 251 by 39, we get 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 3976.0
If we take 234 away from 251, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
If we divide 170 by 39, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3976.4
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
If we divide 140 by 39, we get 3 and a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 3976.43
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
The number 39 fits into 230 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 3976.435
Subtract 195 from 230 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 10:
350 divided by 39 is 8 with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 3976.4358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
If we divide 380 by 39, we get 9 and a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 3976.43589
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 3976.435897
Subtracting 273 from 290 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
39 goes into 170 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 3976.4358974
Deduct 156 from 170 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
140 divided by 39 is 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 3976.43589743
Subtract 117 from 140 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 3976.43589743 with a remaining 2.3e-08.
