We look at the division of 73301452 by 312 
We want to divide 73301452 by 312.

On to step 1:
312 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 312

Moving on to step 2:
If we divide 73 by 312, we get 0 and a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Include the next digit (3) from the dividend after 73, then repeat: 733 / 312

Moving on to step 3:
312 goes into 733 2 times with a remainder of 109.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 624 from 733 and we're left with 109.
Grab the next digit (0) from the dividend, add it to 109, then carry on: 1090 / 312

Advancing to step 4:
1090 divided by 312 is 3 with a remainder of 154.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 936 from 1090 and we're left with 154.
Take the next digit (1) from the dividend and append it to 154, then repeat: 1541 / 312

On to step 5:
1541 divided by 312 is 4 with a remainder of 293.
Write down 4 as next digit of the result. 
Result so far: 234.0
Subtracting 1248 from 1541 leaves us with 293.
Bring next digit (4) of the dividend behind the 293 and repeat the process: 2934 / 312

On to step 6:
The number 312 fits into 2934 9 times, leaving a remainder of 126.
Use 9 as the next digit of our solution. 
Result so far: 2349.0
Subtracting 2808 from 2934 leaves us with 126.
Bring next digit (5) of the dividend behind the 126 and repeat the process: 1265 / 312

Moving on to step 7:
1265 divided by 312 is 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 23494.0
The remainder is 17 after subtracting 1248 from 1265.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 312

Going ahead to step 8:
312 goes into 172 0 times with a remainder of 172.
The number 0 becomes the next digit in our result. 
Result so far: 234940.0
Deduct 0 from 172 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 9:
The number 312 fits into 1720 5 times, leaving a remainder of 160.
The number 5 becomes the next digit in our result. 
Result so far: 234940.5
Subtracting 1560 from 1720 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
When dividing 1600 by 312, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 234940.55
If we take 1560 away from 1600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 234940.55, with a leftover of 0.04.
