We're dividing 644922 by 84 
We want to figure out the number of times 644922 can be divided by 84.

Step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 84

Moving on to step 2:
When dividing 64 by 84, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 84

Advancing to step 3:
644 divided by 84 is 7 with a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 588 from 644 to get 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 84

Step 4:
84 goes into 569 6 times with a remainder of 65.
Write down 6 as next digit of the result. 
Result so far: 76.0
Subtract 504 from 569 to get 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 84

Moving 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: 767.0
The remainder is 64 after subtracting 588 from 652.
Take the next digit (2) from the dividend and append it to 64, then repeat: 642 / 84

On to step 6:
When dividing 642 by 84, we get 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 7677.0
If we subtract 588 from 642, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
540 divided by 84 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 7677.6
Deduct 504 from 540 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 8:
If we divide 360 by 84, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 7677.64
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
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: 7677.642
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 10:
84 goes into 720 8 times with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 7677.6428
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.

Going ahead to 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: 7677.64285
Subtracting 420 from 480 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
600 divided by 84 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 7677.642857
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.

Let's proceed to step 13:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 7677.6428571
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.

Going ahead to step 14:
84 goes into 360 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 7677.64285714
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.

The final result is 7677.64285714 with a remainder of 2.4e-08.
