We're dividing 958854 by 21 
Let's see how many times 21 fits into 958854.

Let's proceed to 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
Subtracting 0 from 9 leaves us with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 21

Going ahead to step 2:
If we divide 95 by 21, we get 4 and a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 84 from 95, we get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 21

Moving on to step 3:
118 divided by 21 is 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 105 from 118, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 21

Let's proceed to step 4:
When dividing 138 by 21, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 456.0
Deduct 126 from 138 and we're left with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 21

Moving on to step 5:
When dividing 125 by 21, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 4565.0
Subtracting 105 from 125 leaves us with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 21

On to step 6:
21 can be fit into 204 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 45659.0
Subtracting 189 from 204 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.

Step 7:
21 goes into 150 7 times with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 45659.7
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.

Moving on to step 8:
When dividing 30 by 21, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 45659.71
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.

Let's proceed to step 9:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 45659.714
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.

Moving on to step 10:
60 divided by 21 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 45659.7142
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.

On to step 11:
21 goes into 180 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 45659.71428
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.

On to step 12:
21 goes into 120 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 45659.714285
Deduct 105 from 120 and we're left 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.

On to step 13:
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: 45659.7142857
If we subtract 147 from 150, we 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.

Moving on to 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: 45659.71428571
Subtract 21 from 30 to 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.

In conclusion, the division gives 45659.71428571 with a balance of 9e-09.
