We look at the division of 258313 by 61 
We're looking to find how many times 61 goes into 258313.

On to step 1:
The number 61 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 61

Step 2:
25 divided by 61 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 61

Let's proceed to step 3:
258 divided by 61 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 14 after subtracting 244 from 258.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 61

Step 4:
61 goes into 143 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 122 from 143, we get 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 61

On to step 5:
When dividing 211 by 61, we get 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 423.0
If we take 183 away from 211, we end up with 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 61

Step 6:
If we divide 283 by 61, we get 4 and a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 4234.0
If we take 244 away from 283, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
61 goes into 390 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 4234.6
The remainder is 24 after subtracting 366 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
If we divide 240 by 61, we get 3 and a remainder of 57.
The next digit of our result is 3. 
Result so far: 4234.63
Deduct 183 from 240 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 9:
The number 61 fits into 570 9 times, leaving a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 4234.639
Subtract 549 from 570 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
61 can be fit into 210 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 4234.6393
If we take 183 away from 210, we end up 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.

Advancing to step 11:
61 goes into 270 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 4234.63934
Deduct 244 from 270 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
61 can be fit into 260 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4234.639344
If we take 244 away from 260, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 4234.639344, with a leftover of 1.6e-06.
