Let's divide 12288039 by 73
Our goal is to divide 12288039 by 73.

On to step 1:
When dividing 1 by 73, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 73

Step 2:
73 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 73

Going ahead to step 3:
When dividing 122 by 73, we get 1 with a remainder of 49.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 73 from 122 and we're left with 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 73

Let's proceed to step 4:
73 can be fit into 498 6 times, resulting in a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 438 away from 498, we end up with 60.
Grab the next digit (8) from the dividend, add it to 60, then carry on: 608 / 73

Advancing to step 5:
73 can be fit into 608 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 168.0
If we subtract 584 from 608, we get 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 73

Going ahead to step 6:
240 divided by 73 is 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 1683.0
Deduct 219 from 240 and we're left with 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 73

Advancing to step 7:
If we divide 213 by 73, we get 2 and a remainder of 67.
The next digit of our result is 2. 
Result so far: 16832.0
If we subtract 146 from 213, we get 67.
Grab the next digit (9) from the dividend, add it to 67, then carry on: 679 / 73

Going ahead to step 8:
If we divide 679 by 73, we get 9 and a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 168329.0
The remainder is 22 after subtracting 657 from 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
When dividing 220 by 73, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 168329.3
If we subtract 219 from 220, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
If we divide 10 by 73, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 168329.3
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
73 can be fit into 100 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 168329.301
Deduct 73 from 100 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
73 goes into 270 3 times with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 168329.3013
Deduct 219 from 270 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
When dividing 510 by 73, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 168329.30136
Subtracting 438 from 510 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
The number 73 fits into 720 9 times, leaving a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 168329.301369
If we subtract 657 from 720, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 15:
If we divide 630 by 73, we get 8 and a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 168329.3013698
The remainder is 46 after subtracting 584 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 16:
If we divide 460 by 73, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 168329.30136986
If we take 438 away from 460, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 168329.30136986, with a leftover of 2.2e-08.
