We're dividing 968841 by 21 
We want to divide 968841 by 21.

Step 1:
When dividing 9 by 21, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 21

Going ahead to step 2:
21 can be fit into 96 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 84 from 96 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 21

Let's proceed to step 3:
When dividing 128 by 21, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Subtracting 126 from 128 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 21

Step 4:
When dividing 28 by 21, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 461.0
Deduct 21 from 28 and we're left with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 21

Let's proceed to step 5:
When dividing 74 by 21, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 4613.0
If we subtract 63 from 74, we get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 21

Let's proceed to step 6:
The number 21 fits into 111 5 times, leaving a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 46135.0
The remainder is 6 after subtracting 105 from 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
21 can be fit into 60 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 46135.2
Deduct 42 from 60 and we're left 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.

Going ahead to step 8:
When dividing 180 by 21, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 46135.28
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
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: 46135.285
Subtracting 105 from 120 leaves us 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 10:
21 can be fit into 150 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 46135.2857
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.

On to step 11:
If we divide 30 by 21, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 46135.28571
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.

Step 12:
90 divided by 21 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 46135.285714
Deduct 84 from 90 and we're left 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.

Advancing to step 13:
If we divide 60 by 21, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 46135.2857142
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.

On to step 14:
180 divided by 21 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 46135.28571428
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 46135.28571428 with a remainder of 1.2e-08.
