799252 divided by 21 
Let's see how many times 21 fits into 799252.

Advancing to step 1:
When dividing 7 by 21, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 21

Step 2:
If we divide 79 by 21, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 63 from 79 to get 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 21

Advancing to step 3:
21 goes into 169 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we take 168 away from 169, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 21

Moving on to step 4:
The number 21 fits into 12 0 times, leaving a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 380.0
If we take 0 away from 12, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 21

Let's proceed to step 5:
125 divided by 21 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 3805.0
If we take 105 away from 125, we end up with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 21

Advancing to step 6:
The number 21 fits into 202 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 38059.0
Subtract 189 from 202 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.

Going ahead to step 7:
When dividing 130 by 21, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 38059.6
If we take 126 away from 130, we end up with 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 8:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 38059.61
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
If we divide 190 by 21, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 38059.619
The remainder is 1 after subtracting 189 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 21, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 38059.619
If we take 0 away from 10, we end up with 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 11:
21 goes into 100 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 38059.61904
If we subtract 84 from 100, we 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 12:
21 goes into 160 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 38059.619047
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 13:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 38059.6190476
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.

Advancing to step 14:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 38059.61904761
Deduct 21 from 40 and we're left 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.

In conclusion, the division gives 38059.61904761 with a balance of 1.9e-08.
