We look at the division of 90458368 by 305 
We want to figure out the number of times 90458368 can be divided by 305.

Moving on to step 1:
305 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 305

On to step 2:
305 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (4) from the dividend, add it to 90, then carry on: 904 / 305

Step 3:
If we divide 904 by 305, we get 2 and a remainder of 294.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 610 from 904, we get 294.
Include the next digit (5) from the dividend after 294, then repeat: 2945 / 305

On to step 4:
305 goes into 2945 9 times with a remainder of 200.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 2745 from 2945 leaves us with 200.
Bring next digit (8) of the dividend behind the 200 and repeat the process: 2008 / 305

Moving on to step 5:
305 goes into 2008 6 times with a remainder of 178.
Put 6 as the next digit of the answer. 
Result so far: 296.0
If we subtract 1830 from 2008, we get 178.
Take the next digit (3) from the dividend and append it to 178, then repeat: 1783 / 305

Advancing to step 6:
305 can be fit into 1783 5 times, resulting in a remainder of 258.
The number 5 becomes the next digit in our result. 
Result so far: 2965.0
Subtract 1525 from 1783 to get 258.
Grab the next digit (6) from the dividend, add it to 258, then carry on: 2586 / 305

On to step 7:
305 goes into 2586 8 times with a remainder of 146.
Write down 8 as next digit of the result. 
Result so far: 29658.0
Subtracting 2440 from 2586 leaves us with 146.
Take the next digit (8) from the dividend and append it to 146, then repeat: 1468 / 305

Step 8:
If we divide 1468 by 305, we get 4 and a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 296584.0
If we take 1220 away from 1468, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 9:
If we divide 2480 by 305, we get 8 and a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 296584.8
Subtract 2440 from 2480 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 305, we get 1 with a remainder of 95.
Record the quotient 1 as the next digit in the result. 
Result so far: 296584.81
The remainder is 95 after subtracting 305 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 11:
If we divide 950 by 305, we get 3 and a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 296584.813
If we take 915 away from 950, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 305 fits into 350 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 296584.8131
If we subtract 305 from 350, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
305 can be fit into 450 1 times, resulting in a remainder of 145.
Record the quotient 1 as the next digit in the result. 
Result so far: 296584.81311
If we subtract 305 from 450, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Our division results in 296584.81311 with a remaining 0.000145.
