We look at the division of 303810 by 74 
We're looking to find how many times 74 goes into 303810.

On to step 1:
If we divide 3 by 74, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 74

Moving on to step 2:
74 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 74

On to step 3:
74 goes into 303 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 296 from 303, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 74

Step 4:
The number 74 fits into 78 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 74 from 78 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 74

Moving on to step 5:
The number 74 fits into 41 0 times, leaving a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 410.0
Deduct 0 from 41 and we're left with 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 74

Step 6:
74 goes into 410 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 4105.0
Deduct 370 from 410 and we're left 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.

Let's proceed to step 7:
If we divide 400 by 74, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 4105.5
The remainder is 30 after subtracting 370 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
74 can be fit into 300 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 4105.54
If we subtract 296 from 300, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
74 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4105.54
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 74, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4105.5405
The remainder is 30 after subtracting 370 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
The number 74 fits into 300 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4105.54054
If we subtract 296 from 300, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
When dividing 40 by 74, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 4105.54054
If we take 0 away from 40, 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.

Moving on to step 13:
74 goes into 400 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 4105.5405405
The remainder is 30 after subtracting 370 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
74 can be fit into 300 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4105.54054054
If we take 296 away from 300, we end up 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.

The final result is 4105.54054054 with a remainder of 4e-09.
