73829379 ÷ 18 
Our goal is to divide 73829379 by 18.

Let's proceed to step 1:
When dividing 7 by 18, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 18

Let's proceed to step 2:
73 divided by 18 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 72 from 73 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 18

Let's proceed to step 3:
18 divided by 18 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 41.0
Subtract 18 from 18 to get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 18

Step 4:
The number 18 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 410.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 18

Going ahead to step 5:
When dividing 29 by 18, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 4101.0
Subtracting 18 from 29 leaves us with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 18

Let's proceed to step 6:
The number 18 fits into 113 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 41016.0
If we take 108 away from 113, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 18

Going ahead to step 7:
18 goes into 57 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 410163.0
Deduct 54 from 57 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 18

Let's proceed to step 8:
18 goes into 39 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 4101632.0
The remainder is 3 after subtracting 36 from 39.
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 9:
18 can be fit into 30 1 times, resulting in a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 4101632.1
Deduct 18 from 30 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 10:
When dividing 120 by 18, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 4101632.16
If we take 108 away from 120, 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.

Going ahead to step 11:
18 can be fit into 120 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 4101632.166
Subtracting 108 from 120 leaves us 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.

The final outcome is 4101632.166, with a leftover of 0.0012.
