We divide 949569 by 21
We want to figure out the number of times 949569 can be divided by 21.

Advancing to step 1:
The number 21 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 21

Step 2:
94 divided by 21 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 84 from 94, we get 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 21

On to step 3:
21 can be fit into 109 5 times, resulting in a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtract 105 from 109 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 21

Going ahead to step 4:
45 divided by 21 is 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 452.0
Subtracting 42 from 45 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 21

On to step 5:
21 goes into 36 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 4521.0
Deduct 21 from 36 and we're left with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 21

Step 6:
159 divided by 21 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 45217.0
Subtract 147 from 159 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
When dividing 120 by 21, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 45217.5
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
If we divide 150 by 21, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 45217.57
Subtracting 147 from 150 leaves us 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.

Let's proceed to step 9:
When dividing 30 by 21, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 45217.571
If we take 21 away from 30, we end up 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 10:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 45217.5714
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.

Moving on to step 11:
60 divided by 21 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 45217.57142
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.

Step 12:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 45217.571428
Subtract 168 from 180 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
When dividing 120 by 21, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 45217.5714285
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.

Moving on to step 14:
If we divide 150 by 21, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 45217.57142857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 45217.57142857 with a remainder of 3e-09.
