47065401 ÷ 21 
Let's see how many times 21 fits into 47065401.

On to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 21

Advancing to step 2:
21 can be fit into 47 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 42 from 47 to get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 21

Step 3:
21 can be fit into 50 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 42 from 50 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 21

Going ahead to step 4:
86 divided by 21 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 224.0
Subtract 84 from 86 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 21

Going ahead to step 5:
25 divided by 21 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 2241.0
Subtracting 21 from 25 leaves us with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 21

Going ahead to step 6:
44 divided by 21 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 22412.0
If we subtract 42 from 44, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 21

Let's proceed to step 7:
21 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 224120.0
Deduct 0 from 20 and we're left with 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 21

Moving on to step 8:
21 can be fit into 201 9 times, resulting in a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 2241209.0
If we take 189 away from 201, 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 9:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 2241209.5
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.

On to step 10:
150 divided by 21 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 2241209.57
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:
21 can be fit into 30 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 2241209.571
The remainder is 9 after subtracting 21 from 30.
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 12:
The number 21 fits into 90 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 2241209.5714
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 13:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2241209.57142
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.

Advancing to step 14:
If we divide 180 by 21, we get 8 and a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 2241209.571428
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.

On to step 15:
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: 2241209.5714285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 16:
When dividing 150 by 21, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 2241209.57142857
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.

Our division results in 2241209.57142857 with a remaining 3e-09.
