995515 divided by 21 
We're looking to find how many times 21 goes into 995515.

Going ahead to step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 21

Moving on to step 2:
21 goes into 99 4 times with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 84 from 99, we get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 21

Let's proceed to step 3:
155 divided by 21 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 147 from 155 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 21

Let's proceed to step 4:
21 can be fit into 85 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
If we take 84 away from 85, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 21

Going ahead to step 5:
11 divided by 21 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 4740.0
Deduct 0 from 11 and we're left with 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 21

Moving on to step 6:
When dividing 115 by 21, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 47405.0
Subtract 105 from 115 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 47405.4
Deduct 84 from 100 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.

Going ahead to step 8:
21 goes into 160 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 47405.47
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 9:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 47405.476
Subtract 126 from 130 to 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.

On to step 10:
When dividing 40 by 21, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 47405.4761
If we take 21 away from 40, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
The number 21 fits into 190 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 47405.47619
Subtract 189 from 190 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
When dividing 10 by 21, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 47405.47619
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
21 can be fit into 100 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 47405.4761904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
When dividing 160 by 21, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 47405.47619047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 47405.47619047, with a leftover of 1.3e-08.
