We look at the division of 258443 by 84 
Let's see how many times 84 fits into 258443.

Let's proceed to step 1:
84 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
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 84

Moving on to step 2:
25 divided by 84 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
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 / 84

Step 3:
258 divided by 84 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 252 from 258 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 84

On to step 4:
64 divided by 84 is 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 64 to get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 84

Advancing to step 5:
If we divide 644 by 84, we get 7 and a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
Deduct 588 from 644 and we're left with 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 84

Let's proceed to step 6:
The number 84 fits into 563 6 times, leaving a remainder of 59.
Use 6 as the next digit of our solution. 
Result so far: 3076.0
Subtracting 504 from 563 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
If we divide 590 by 84, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 3076.7
If we subtract 588 from 590, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
84 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 3076.7
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 84, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 3076.702
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
320 divided by 84 is 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 3076.7023
Deduct 252 from 320 and we're left with 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 11:
84 goes into 680 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 3076.70238
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
80 divided by 84 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 3076.70238
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 3076.7023809
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
84 goes into 440 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 3076.70238095
If we subtract 420 from 440, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3076.70238095 with a remaining 2e-08.
