We're dividing 59520 by 21 
We want to figure out the number of times 59520 can be divided by 21.

Let's proceed to step 1:
21 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 21

Step 2:
59 divided by 21 is 2 with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 42 from 59 and we're left with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 21

On to step 3:
When dividing 175 by 21, we get 8 with a remainder of 7.
The next digit of our result is 8. 
Result so far: 28.0
Subtracting 168 from 175 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 21

On to step 4:
21 goes into 72 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 283.0
Subtracting 63 from 72 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 21

Moving on to step 5:
When dividing 90 by 21, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 2834.0
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 6:
21 goes into 60 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2834.2
If we take 42 away from 60, we end up 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.

On to step 7:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 2834.28
Subtracting 168 from 180 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.

Advancing to step 8:
21 goes into 120 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 2834.285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
When dividing 150 by 21, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 2834.2857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
30 divided by 21 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 2834.28571
Subtracting 21 from 30 leaves us 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.

Advancing to step 11:
When dividing 90 by 21, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 2834.285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
The number 21 fits into 60 2 times, leaving a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 2834.2857142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
180 divided by 21 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 2834.28571428
If we take 168 away from 180, 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.

The quotient of the division is 2834.28571428, and the remainder is 1.2e-08.
