521247 ÷ 84 
We want to divide 521247 by 84.

Advancing 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.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 84

Moving on to step 2:
84 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 84

Advancing to step 3:
84 can be fit into 521 6 times, resulting in a remainder of 17.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 504 from 521 and we're left with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 84

Step 4:
If we divide 172 by 84, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 62.0
The remainder is 4 after subtracting 168 from 172.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 84

On to step 5:
84 goes into 44 0 times with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 620.0
Subtracting 0 from 44 leaves us with 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 84

Let's proceed to step 6:
The number 84 fits into 447 5 times, leaving a remainder of 27.
Use 5 as the next digit of our solution. 
Result so far: 6205.0
Deduct 420 from 447 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
84 goes into 270 3 times with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 6205.3
Deduct 252 from 270 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
84 can be fit into 180 2 times, resulting in a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 6205.32
The remainder is 12 after subtracting 168 from 180.
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 9:
If we divide 120 by 84, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 6205.321
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.

Going ahead to step 10:
When dividing 360 by 84, we get 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 6205.3214
Subtracting 336 from 360 leaves us 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 11:
84 goes into 240 2 times with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 6205.32142
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.

Advancing to step 12:
720 divided by 84 is 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 6205.321428
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.

Moving on to step 13:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 6205.3214285
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
If we divide 600 by 84, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 6205.32142857
If we take 588 away from 600, we end up 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.

Our division results in 6205.32142857 with a remaining 1.2e-08.
