712122 divided by 84 
Our goal is to divide 712122 by 84.

Step 1:
7 divided by 84 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 84

On to step 2:
84 can be fit into 71 0 times, resulting in a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 84

Step 3:
The number 84 fits into 712 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 672 from 712 to get 40.
Append the next digit (1) from the dividend to 40 and continue with: 401 / 84

Moving on to step 4:
84 can be fit into 401 4 times, resulting in a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 336 from 401 leaves us with 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 84

On to step 5:
If we divide 652 by 84, we get 7 and a remainder of 64.
Put 7 as the next digit of the answer. 
Result so far: 847.0
Subtract 588 from 652 to get 64.
Bring next digit (2) of the dividend behind the 64 and repeat the process: 642 / 84

Let's proceed to step 6:
If we divide 642 by 84, we get 7 and a remainder of 54.
Write down 7 as next digit of the result. 
Result so far: 8477.0
The remainder is 54 after subtracting 588 from 642.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
84 can be fit into 540 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 8477.6
If we take 504 away from 540, we end up 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.

Let's proceed to step 8:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 8477.64
If we take 336 away from 360, we end up with 24.
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 9:
The number 84 fits into 240 2 times, leaving a remainder of 72.
The next digit of our result is 2. 
Result so far: 8477.642
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 10:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8477.6428
Subtracting 672 from 720 leaves us with 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 11:
When dividing 480 by 84, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 8477.64285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 8477.642857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
84 goes into 120 1 times with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 8477.6428571
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 14:
If we divide 360 by 84, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8477.64285714
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 8477.64285714 with a balance of 2.4e-08.
