43411 divided by 21 
We're looking to find how many times 21 goes into 43411.

Advancing to step 1:
21 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 21

Step 2:
21 can be fit into 43 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 42 from 43 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 21

Going ahead to step 3:
If we divide 14 by 21, we get 0 and a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 21

Step 4:
When dividing 141 by 21, we get 6 with a remainder of 15.
The next digit of our result is 6. 
Result so far: 206.0
Subtracting 126 from 141 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 21

Let's proceed to step 5:
21 can be fit into 151 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 2067.0
Deduct 147 from 151 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 6:
When dividing 40 by 21, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 2067.1
Deduct 21 from 40 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
21 goes into 190 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 2067.19
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
10 divided by 21 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2067.19
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
21 can be fit into 100 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 2067.1904
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
When dividing 160 by 21, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 2067.19047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 11:
If we divide 130 by 21, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 2067.190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
When dividing 40 by 21, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 2067.1904761
If we subtract 21 from 40, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
21 can be fit into 190 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 2067.19047619
If we take 189 away from 190, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 2067.19047619, with a leftover of 1e-09.
