We're dividing 833862 by 21 
We want to figure out the number of times 833862 can be divided by 21.

Let's proceed to step 1:
21 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 21

On to step 2:
The number 21 fits into 83 3 times, leaving a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 63 from 83, we get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 21

Step 3:
203 divided by 21 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 39.0
Deduct 189 from 203 and we're left with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 21

Let's proceed to step 4:
When dividing 148 by 21, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
Deduct 147 from 148 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 21

Advancing to step 5:
21 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 3970.0
Subtract 0 from 16 to get 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 21

Let's proceed to step 6:
If we divide 162 by 21, we get 7 and a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 39707.0
If we subtract 147 from 162, we get 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 7:
If we divide 150 by 21, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 39707.7
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.

Let's proceed to step 8:
When dividing 30 by 21, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 39707.71
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
90 divided by 21 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 39707.714
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.

Let's proceed to step 10:
60 divided by 21 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 39707.7142
Subtract 42 from 60 to 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.

Moving on to step 11:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 39707.71428
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 12:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 39707.714285
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.

Moving on to step 13:
21 goes into 150 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 39707.7142857
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.

Step 14:
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: 39707.71428571
If we subtract 21 from 30, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 39707.71428571, and the remainder is 9e-09.
