9210435 ÷ 305 
Let's see how many times 305 fits into 9210435.

Let's proceed to step 1:
The number 305 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 305

Moving on to step 2:
305 goes into 92 0 times with a remainder of 92.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 92, we end up with 92.
Include the next digit (1) from the dividend after 92, then repeat: 921 / 305

Let's proceed to step 3:
The number 305 fits into 921 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 915 from 921 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 305

Step 4:
When dividing 60 by 305, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 60 to get 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 305

Moving on to step 5:
604 divided by 305 is 1 with a remainder of 299.
Write down 1 as next digit of the result. 
Result so far: 301.0
If we subtract 305 from 604, we get 299.
Bring next digit (3) of the dividend behind the 299 and repeat the process: 2993 / 305

Advancing to step 6:
When dividing 2993 by 305, we get 9 with a remainder of 248.
The next digit of our result is 9. 
Result so far: 3019.0
Subtracting 2745 from 2993 leaves us with 248.
Take the next digit (5) from the dividend and append it to 248, then repeat: 2485 / 305

Step 7:
305 can be fit into 2485 8 times, resulting in a remainder of 45.
Put 8 as the next digit of the answer. 
Result so far: 30198.0
If we subtract 2440 from 2485, 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.

Step 8:
450 divided by 305 is 1 with a remainder of 145.
Put 1 as the next digit of the answer. 
Result so far: 30198.1
Deduct 305 from 450 and we're left with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Step 9:
When dividing 1450 by 305, we get 4 with a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 30198.14
Deduct 1220 from 1450 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
If we divide 2300 by 305, we get 7 and a remainder of 165.
The next digit of our result is 7. 
Result so far: 30198.147
Deduct 2135 from 2300 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 11:
305 goes into 1650 5 times with a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 30198.1475
If we subtract 1525 from 1650, we get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
The number 305 fits into 1250 4 times, leaving a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 30198.14754
The remainder is 30 after subtracting 1220 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
If we divide 300 by 305, we get 0 and a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 30198.14754
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
305 can be fit into 3000 9 times, resulting in a remainder of 255.
The number 9 becomes the next digit in our result. 
Result so far: 30198.1475409
Subtract 2745 from 3000 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 15:
305 can be fit into 2550 8 times, resulting in a remainder of 110.
Record the quotient 8 as the next digit in the result. 
Result so far: 30198.14754098
The remainder is 110 after subtracting 2440 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 30198.14754098 and a remainder of 1.1e-07.
