Let's divide 246132 by 21
Let's see how many times 21 fits into 246132.

Going ahead to step 1:
2 divided by 21 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 21

Step 2:
24 divided by 21 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 21 from 24.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 21

Advancing to step 3:
36 divided by 21 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 21 from 36 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 21

Let's proceed to step 4:
When dividing 151 by 21, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 147 from 151 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 21

Let's proceed to step 5:
When dividing 43 by 21, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1172.0
If we subtract 42 from 43, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 21

Moving on to step 6:
If we divide 12 by 21, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 11720.0
If we take 0 away from 12, we end up 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 7:
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: 11720.5
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 8:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 11720.57
Deduct 147 from 150 and we're left 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 9:
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: 11720.571
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.

Going ahead to step 10:
If we divide 90 by 21, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 11720.5714
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.

Step 11:
21 goes into 60 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 11720.57142
Subtracting 42 from 60 leaves us 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.

Let's proceed to step 12:
When dividing 180 by 21, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 11720.571428
Deduct 168 from 180 and we're left 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.

Moving on to step 13:
If we divide 120 by 21, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 11720.5714285
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.

Step 14:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 11720.57142857
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.

The final result is 11720.57142857 with a remainder of 3e-09.
