258950 ÷ 39 
Let's see how many times 39 fits into 258950.

On to step 1:
When dividing 2 by 39, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 39

Advancing to step 2:
When dividing 25 by 39, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 39

Advancing to step 3:
When dividing 258 by 39, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 234 from 258, we get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 39

Moving on to step 4:
249 divided by 39 is 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 234 from 249, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 39

Advancing to step 5:
39 can be fit into 155 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 663.0
The remainder is 38 after subtracting 117 from 155.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 39

Advancing to step 6:
When dividing 380 by 39, we get 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 6639.0
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
The number 39 fits into 290 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 6639.7
Subtract 273 from 290 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
39 can be fit into 170 4 times, resulting in a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 6639.74
Subtract 156 from 170 to get 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 9:
140 divided by 39 is 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 6639.743
If we subtract 117 from 140, we 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.

Going ahead to step 10:
When dividing 230 by 39, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 6639.7435
The remainder is 35 after subtracting 195 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
If we divide 350 by 39, we get 8 and a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 6639.74358
If we take 312 away from 350, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
When dividing 380 by 39, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 6639.743589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
39 can be fit into 290 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6639.7435897
Deduct 273 from 290 and we're left 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.

On to step 14:
If we divide 170 by 39, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 6639.74358974
Subtract 156 from 170 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 6639.74358974 and a remainder of 1.4e-08.
