509973 divided by 84 
Let's see how many times 84 fits into 509973.

On to step 1:
5 divided by 84 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 84

Moving on to step 2:
84 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Append the next digit (9) from the dividend to 50 and continue with: 509 / 84

Advancing to step 3:
84 can be fit into 509 6 times, resulting in a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 504 from 509, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 84

Going ahead to step 4:
If we divide 59 by 84, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Deduct 0 from 59 and we're left with 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 84

Advancing to step 5:
When dividing 597 by 84, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 607.0
Deduct 588 from 597 and we're left with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 84

Step 6:
84 goes into 93 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 6071.0
Deduct 84 from 93 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
The number 84 fits into 90 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 6071.1
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
84 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 6071.1
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
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: 6071.107
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.

On to step 10:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 6071.1071
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.

Let's proceed to step 11:
When dividing 360 by 84, we get 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 6071.10714
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.

Moving on to step 12:
If we divide 240 by 84, we get 2 and a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 6071.107142
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.

Step 13:
If we divide 720 by 84, we get 8 and a remainder of 48.
The next digit of our result is 8. 
Result so far: 6071.1071428
Subtract 672 from 720 to 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.

Step 14:
When dividing 480 by 84, we get 5 with a remainder of 60.
The next digit of our result is 5. 
Result so far: 6071.10714285
If we take 420 away from 480, we end up 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.

The quotient of the division is 6071.10714285, and the remainder is 6e-08.
