We look at the division of 258143 by 93 
Let's see how many times 93 fits into 258143.

Advancing to step 1:
93 can be fit into 2 0 times, resulting in 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.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 93

Moving on to step 2:
When dividing 25 by 93, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (8) from the dividend, add it to 25, then carry on: 258 / 93

Advancing to step 3:
If we divide 258 by 93, we get 2 and a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 186 from 258 to get 72.
Append the next digit (1) from the dividend to 72 and continue with: 721 / 93

Moving on to step 4:
721 divided by 93 is 7 with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 70 after subtracting 651 from 721.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 93

Moving on to step 5:
93 goes into 704 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 277.0
If we take 651 away from 704, we end up with 53.
Bring next digit (3) of the dividend behind the 53 and repeat the process: 533 / 93

Step 6:
93 goes into 533 5 times with a remainder of 68.
The next digit of our result is 5. 
Result so far: 2775.0
If we subtract 465 from 533, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 7:
When dividing 680 by 93, we get 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 2775.7
If we subtract 651 from 680, 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.

Step 8:
93 goes into 290 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 2775.73
The remainder is 11 after subtracting 279 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
93 goes into 110 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 2775.731
The remainder is 17 after subtracting 93 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
93 goes into 170 1 times with a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 2775.7311
If we take 93 away from 170, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 2775.7311, with a leftover of 0.00077.
