73818 divided by 21 
Our goal is to divide 73818 by 21.

Moving on to step 1:
7 divided by 21 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 21

Moving on to step 2:
The number 21 fits into 73 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 10 after subtracting 63 from 73.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 21

On to step 3:
If we divide 108 by 21, we get 5 and a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 35.0
If we take 105 away from 108, we end up with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 21

Going ahead to step 4:
21 goes into 31 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 351.0
If we subtract 21 from 31, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 21

Advancing to step 5:
If we divide 108 by 21, we get 5 and a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 3515.0
If we take 105 away from 108, we end up 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.

Going ahead to step 6:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 3515.1
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.

Let's proceed to step 7:
When dividing 90 by 21, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 3515.14
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.

Let's proceed to step 8:
21 goes into 60 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 3515.142
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.

Moving on to step 9:
When dividing 180 by 21, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 3515.1428
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 10:
120 divided by 21 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3515.14285
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.

On to step 11:
When dividing 150 by 21, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3515.142857
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.

Step 12:
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: 3515.1428571
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.

Going ahead to step 13:
When dividing 90 by 21, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 3515.14285714
If we take 84 away from 90, we end up 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.

The final outcome is 3515.14285714, with a leftover of 6e-09.
