We're dividing 139015 by 39 
Our goal is to divide 139015 by 39.

Advancing to step 1:
1 divided by 39 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 39

Step 2:
39 goes into 13 0 times with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 39

Going ahead to step 3:
When dividing 139 by 39, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 117 from 139 to get 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 39

Advancing to step 4:
220 divided by 39 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 195 away from 220, we end up with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 39

Advancing to step 5:
39 goes into 251 6 times with a remainder of 17.
The next digit of our result is 6. 
Result so far: 356.0
If we take 234 away from 251, we end up with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 39

Let's proceed to step 6:
39 can be fit into 175 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 3564.0
Subtract 156 from 175 to get 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 7:
39 can be fit into 190 4 times, resulting in a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 3564.4
Deduct 156 from 190 and we're left 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.

Moving on to step 8:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 3564.48
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3564.487
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
When dividing 70 by 39, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 3564.4871
If we take 39 away from 70, we end up 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.

Let's proceed to step 11:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 3564.48717
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.

Moving on to step 12:
39 goes into 370 9 times with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 3564.487179
Subtracting 351 from 370 leaves us 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.

Let's proceed to step 13:
39 can be fit into 190 4 times, resulting in a remainder of 34.
The next digit of our result is 4. 
Result so far: 3564.4871794
Subtract 156 from 190 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
39 goes into 340 8 times with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 3564.48717948
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.

The final result is 3564.48717948 with a remainder of 2.8e-08.
