We look at the division of 644958 by 84 
Our goal is to divide 644958 by 84.

Moving on to step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 84

Advancing to step 2:
84 goes into 64 0 times with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 84

Moving on to step 3:
84 can be fit into 644 7 times, resulting in a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 588 away from 644, we end up with 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 84

Let's proceed to step 4:
84 goes into 569 6 times with a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 65 after subtracting 504 from 569.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 84

Moving on to step 5:
84 goes into 655 7 times with a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 767.0
Deduct 588 from 655 and we're left with 67.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 84

Advancing to step 6:
678 divided by 84 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 7678.0
Deduct 672 from 678 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
The number 84 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7678.0
The remainder is 60 after subtracting 0 from 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 8:
The number 84 fits into 600 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 7678.07
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 84, we get 1 and a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 7678.071
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.

Step 10:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 7678.0714
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.

Advancing to step 11:
240 divided by 84 is 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 7678.07142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 12:
84 goes into 720 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 7678.071428
Deduct 672 from 720 and we're left 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.

Advancing to step 13:
The number 84 fits into 480 5 times, leaving a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 7678.0714285
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.

Advancing to step 14:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 7678.07142857
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 7678.07142857 and a remainder of 1.2e-08.
