868658 ÷ 84 
Let's see how many times 84 fits into 868658.

Going ahead to step 1:
If we divide 8 by 84, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 84

Let's proceed to step 2:
When dividing 86 by 84, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 84 from 86 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 84

Advancing to step 3:
When dividing 28 by 84, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 84

On to step 4:
If we divide 286 by 84, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 103.0
The remainder is 34 after subtracting 252 from 286.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 84

Step 5:
If we divide 345 by 84, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 1034.0
If we take 336 away from 345, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 84

Advancing to step 6:
When dividing 98 by 84, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 10341.0
Deduct 84 from 98 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
The number 84 fits into 140 1 times, leaving a remainder of 56.
Put 1 as the next digit of the answer. 
Result so far: 10341.1
Subtract 84 from 140 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
If we divide 560 by 84, we get 6 and a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 10341.16
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
If we divide 560 by 84, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 10341.166
Subtract 504 from 560 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 10341.166 and a remainder of 0.0056.
