64301420 divided by 84 
Our goal is to divide 64301420 by 84.

Advancing to step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 84

Going ahead to step 2:
84 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 84

Moving on to step 3:
The number 84 fits into 643 7 times, leaving a remainder of 55.
The next digit of our result is 7. 
Result so far: 7.0
If we take 588 away from 643, we end up with 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 84

Step 4:
If we divide 550 by 84, we get 6 and a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtract 504 from 550 to get 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 84

Let's proceed to step 5:
When dividing 461 by 84, we get 5 with a remainder of 41.
The number 5 becomes the next digit in our result. 
Result so far: 765.0
The remainder is 41 after subtracting 420 from 461.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 84

Let's proceed to step 6:
If we divide 414 by 84, we get 4 and a remainder of 78.
Record the quotient 4 as the next digit in the result. 
Result so far: 7654.0
If we take 336 away from 414, we end up with 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 84

On to step 7:
782 divided by 84 is 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 76549.0
Subtract 756 from 782 to get 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 84

Going ahead to step 8:
When dividing 260 by 84, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 765493.0
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 765493.0
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
800 divided by 84 is 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 765493.09
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
440 divided by 84 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 765493.095
Subtract 420 from 440 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 765493.0952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 13:
If we divide 320 by 84, we get 3 and a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 765493.09523
Deduct 252 from 320 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
The number 84 fits into 680 8 times, leaving a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 765493.095238
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 15:
The number 84 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 765493.095238
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 16:
84 can be fit into 800 9 times, resulting in a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 765493.09523809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 765493.09523809 with a remainder of 4.4e-08.
