We divide 643413 by 84
Let's see how many times 84 fits into 643413.

Step 1:
6 divided by 84 is 0 with 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.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 84

Going ahead to step 2:
When dividing 64 by 84, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 84

Going ahead to step 3:
The number 84 fits into 643 7 times, leaving a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 588 from 643, we get 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 84

Going ahead to step 4:
84 can be fit into 554 6 times, resulting in a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 50 after subtracting 504 from 554.
Bring next digit (1) of the dividend behind the 50 and repeat the process: 501 / 84

Going ahead to step 5:
The number 84 fits into 501 5 times, leaving a remainder of 81.
The number 5 becomes the next digit in our result. 
Result so far: 765.0
If we subtract 420 from 501, we get 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 84

Step 6:
813 divided by 84 is 9 with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 7659.0
Subtracting 756 from 813 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 7:
84 goes into 570 6 times with a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 7659.6
Deduct 504 from 570 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
660 divided by 84 is 7 with a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 7659.67
The remainder is 72 after subtracting 588 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
720 divided by 84 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 7659.678
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 10:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 7659.6785
Deduct 420 from 480 and we're left 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.

Going ahead to step 11:
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: 7659.67857
Deduct 588 from 600 and we're left 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.

Going ahead to step 12:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 7659.678571
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
84 goes into 360 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 7659.6785714
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.

Going ahead to step 14:
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: 7659.67857142
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.

The quotient of the division is 7659.67857142, and the remainder is 7.2e-08.
