4081318 divided by 21 
We're looking to find how many times 21 goes into 4081318.

Advancing 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
If we take 0 away from 4, we end up with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 21

On to step 2:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 19 after subtracting 21 from 40.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 21

Going ahead to step 3:
21 can be fit into 198 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 189 from 198 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 21

On to step 4:
If we divide 91 by 21, we get 4 and a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 194.0
Subtracting 84 from 91 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 21

Going ahead to step 5:
73 divided by 21 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 1943.0
Subtracting 63 from 73 leaves us with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 21

Step 6:
When dividing 101 by 21, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 19434.0
Deduct 84 from 101 and we're left with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 21

On to step 7:
178 divided by 21 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 194348.0
If we take 168 away from 178, we end up with 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 8:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 194348.4
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.

Moving on to step 9:
160 divided by 21 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 194348.47
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 194348.476
Deduct 126 from 130 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.

Going ahead to step 11:
The number 21 fits into 40 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 194348.4761
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.

Moving on to step 12:
If we divide 190 by 21, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 194348.47619
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.

Advancing to step 13:
When dividing 10 by 21, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 194348.47619
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.

On to step 14:
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: 194348.4761904
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.

Moving on to step 15:
21 goes into 160 7 times with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 194348.47619047
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.

The quotient of the division is 194348.47619047, and the remainder is 1.3e-08.
