258200 ÷ 84 
We want to divide 258200 by 84.

Let's proceed to step 1:
84 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 84

Moving on to step 2:
If we divide 25 by 84, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 84

On to step 3:
When dividing 258 by 84, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 252 from 258 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 84

Going ahead to step 4:
84 can be fit into 62 0 times, resulting in a remainder of 62.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 62 after subtracting 0 from 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 84

Moving on to step 5:
When dividing 620 by 84, we get 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 307.0
If we take 588 away from 620, we end up with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 84

On to step 6:
320 divided by 84 is 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 3073.0
Subtract 252 from 320 to 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.

Moving on to step 7:
84 goes into 680 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 3073.8
If we subtract 672 from 680, we 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.

Let's proceed to step 8:
If we divide 80 by 84, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 3073.8
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
84 goes into 800 9 times with a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 3073.809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
440 divided by 84 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 3073.8095
Subtract 420 from 440 to 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.

On to step 11:
If we divide 200 by 84, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 3073.80952
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.

Advancing to step 12:
320 divided by 84 is 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 3073.809523
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.

On to step 13:
If we divide 680 by 84, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 3073.8095238
Deduct 672 from 680 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
80 divided by 84 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 3073.8095238
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 3073.8095238 with a remainder of 8e-08.
