258256 ÷ 39 
We want to divide 258256 by 39.

On to step 1:
When dividing 2 by 39, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 39

Advancing to step 2:
The number 39 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 39

Let's proceed to step 3:
The number 39 fits into 258 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 24 after subtracting 234 from 258.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 39

Step 4:
39 can be fit into 242 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Subtracting 234 from 242 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 39

Advancing to step 5:
39 can be fit into 85 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 662.0
Subtract 78 from 85 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 39

On to step 6:
If we divide 76 by 39, we get 1 and a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 6621.0
If we take 39 away from 76, we end up with 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 7:
370 divided by 39 is 9 with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 6621.9
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 8:
When dividing 190 by 39, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 6621.94
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 9:
The number 39 fits into 340 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 6621.948
Deduct 312 from 340 and we're left 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.

Let's proceed to step 10:
When dividing 280 by 39, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 6621.9487
If we take 273 away from 280, we end up 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.

Going ahead to step 11:
The number 39 fits into 70 1 times, leaving a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 6621.94871
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.

Let's proceed to step 12:
The number 39 fits into 310 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 6621.948717
If we take 273 away from 310, we end up with 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 13:
370 divided by 39 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 6621.9487179
Subtract 351 from 370 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.

Going ahead to step 14:
39 can be fit into 190 4 times, resulting in a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 6621.94871794
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 6621.94871794 and a remainder of 3.4e-08.
