764221 ÷ 84 
We want to figure out the number of times 764221 can be divided by 84.

Advancing to step 1:
7 divided by 84 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 84

Advancing to step 2:
When dividing 76 by 84, we get 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Grab the next digit (4) from the dividend, add it to 76, then carry on: 764 / 84

Let's proceed to step 3:
If we divide 764 by 84, we get 9 and a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 756 from 764 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 84

Let's proceed to step 4:
82 divided by 84 is 0 with a remainder of 82.
The next digit of our result is 0. 
Result so far: 90.0
The remainder is 82 after subtracting 0 from 82.
Take the next digit (2) from the dividend and append it to 82, then repeat: 822 / 84

Going ahead to step 5:
If we divide 822 by 84, we get 9 and a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
Subtracting 756 from 822 leaves us with 66.
Fetch the next digit (1) from the dividend, attach it to 66 and continue: 661 / 84

On to step 6:
84 can be fit into 661 7 times, resulting in a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 9097.0
The remainder is 73 after subtracting 588 from 661.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
730 divided by 84 is 8 with a remainder of 58.
Record the quotient 8 as the next digit in the result. 
Result so far: 9097.8
Subtract 672 from 730 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 8:
580 divided by 84 is 6 with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 9097.86
The remainder is 76 after subtracting 504 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
The number 84 fits into 760 9 times, leaving a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9097.869
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
40 divided by 84 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9097.869
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
84 can be fit into 400 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 9097.86904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
640 divided by 84 is 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 9097.869047
Subtracting 588 from 640 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
The number 84 fits into 520 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 9097.8690476
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
If we divide 160 by 84, we get 1 and a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 9097.86904761
Deduct 84 from 160 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 9097.86904761 with a remainder of 7.6e-08.
