We're dividing 938589 by 21 
Let's see how many times 21 fits into 938589.

Step 1:
9 divided by 21 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 21

Step 2:
When dividing 93 by 21, we get 4 with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 84 away from 93, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 21

Advancing to step 3:
The number 21 fits into 98 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
Subtract 84 from 98 to get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 21

On to step 4:
The number 21 fits into 145 6 times, leaving a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 446.0
Deduct 126 from 145 and we're left with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 21

Moving on to step 5:
The number 21 fits into 198 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 4469.0
Subtracting 189 from 198 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 21

On to step 6:
The number 21 fits into 99 4 times, leaving a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 44694.0
Deduct 84 from 99 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.

Moving on to step 7:
150 divided by 21 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 44694.7
The remainder is 3 after subtracting 147 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
30 divided by 21 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 44694.71
Deduct 21 from 30 and we're left 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.

Moving on to step 9:
90 divided by 21 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 44694.714
If we take 84 away from 90, we end up 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:
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: 44694.7142
If we take 42 away from 60, we end up 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.

Advancing to step 11:
When dividing 180 by 21, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 44694.71428
Subtracting 168 from 180 leaves us with 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 12:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 44694.714285
Subtract 105 from 120 to 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.

Step 13:
When dividing 150 by 21, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 44694.7142857
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 14:
If we divide 30 by 21, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 44694.71428571
Deduct 21 from 30 and we're left 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.

The quotient of the division is 44694.71428571, and the remainder is 9e-09.
