We're dividing 942357 by 21 
We want to divide 942357 by 21.

Moving on to step 1:
9 divided by 21 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 21

Step 2:
21 goes into 94 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 84 from 94 and we're left with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 21

Moving on to step 3:
102 divided by 21 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 84 from 102 and we're left with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 21

Going ahead to step 4:
21 can be fit into 183 8 times, resulting in a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 448.0
Deduct 168 from 183 and we're left with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 21

Let's proceed to step 5:
21 goes into 155 7 times with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 4487.0
The remainder is 8 after subtracting 147 from 155.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 21

Going ahead to step 6:
The number 21 fits into 87 4 times, leaving a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 44874.0
Subtracting 84 from 87 leaves us 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 7:
21 goes into 30 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 44874.1
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.

Advancing to step 8:
90 divided by 21 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 44874.14
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 44874.142
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 10:
The number 21 fits into 180 8 times, leaving a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 44874.1428
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.

On to step 11:
If we divide 120 by 21, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 44874.14285
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.

Moving on to step 12:
If we divide 150 by 21, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 44874.142857
Subtracting 147 from 150 leaves us 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.

Step 13:
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: 44874.1428571
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.

On to step 14:
21 can be fit into 90 4 times, resulting in a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 44874.14285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 44874.14285714, and the remainder is 6e-09.
