Let's divide 56521 by 84
We want to figure out the number of times 56521 can be divided by 84.

On to step 1:
84 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 84

On to step 2:
84 goes into 56 0 times with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Take the next digit (5) from the dividend and append it to 56, then repeat: 565 / 84

Step 3:
84 goes into 565 6 times with a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 504 from 565 and we're left with 61.
Grab the next digit (2) from the dividend, add it to 61, then carry on: 612 / 84

Let's proceed to step 4:
The number 84 fits into 612 7 times, leaving a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
The remainder is 24 after subtracting 588 from 612.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 84

Moving on to step 5:
84 can be fit into 241 2 times, resulting in a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 672.0
The remainder is 73 after subtracting 168 from 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 6:
730 divided by 84 is 8 with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 672.8
The remainder is 58 after subtracting 672 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
580 divided by 84 is 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 672.86
Subtract 504 from 580 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
760 divided by 84 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 672.869
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
When dividing 40 by 84, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 672.869
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
84 can be fit into 400 4 times, resulting in a remainder of 64.
The next digit of our result is 4. 
Result so far: 672.86904
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 11:
84 goes into 640 7 times with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 672.869047
Subtract 588 from 640 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
84 can be fit into 520 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 672.8690476
Deduct 504 from 520 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
84 can be fit into 160 1 times, resulting in a remainder of 76.
Put 1 as the next digit of the answer. 
Result so far: 672.86904761
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 672.86904761 with a remaining 7.6e-08.
