921204 ÷ 84 
Our goal is to divide 921204 by 84.

Going ahead to step 1:
When dividing 9 by 84, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 84

On to step 2:
92 divided by 84 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 84 from 92 leaves us with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 84

On to step 3:
81 divided by 84 is 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (2) from the dividend, attach it to 81 and continue: 812 / 84

Let's proceed to step 4:
When dividing 812 by 84, we get 9 with a remainder of 56.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtracting 756 from 812 leaves us with 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 84

Advancing to step 5:
84 goes into 560 6 times with a remainder of 56.
The next digit of our result is 6. 
Result so far: 1096.0
If we subtract 504 from 560, we get 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 84

Moving on to step 6:
When dividing 564 by 84, we get 6 with a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 10966.0
If we subtract 504 from 564, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
The number 84 fits into 600 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 10966.7
Subtracting 588 from 600 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
84 goes into 120 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 10966.71
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
84 goes into 360 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 10966.714
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
If we divide 240 by 84, we get 2 and a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 10966.7142
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
If we divide 720 by 84, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 10966.71428
If we subtract 672 from 720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 12:
If we divide 480 by 84, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 10966.714285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
When dividing 600 by 84, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 10966.7142857
If we take 588 away from 600, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
84 goes into 120 1 times with a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 10966.71428571
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 10966.71428571 and a remainder of 3.6e-08.
