Let's divide 17770434 by 309
We're looking to find how many times 309 goes into 17770434.

Moving on to step 1:
309 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 309

Let's proceed to step 2:
The number 309 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (7) from the dividend after 17, then repeat: 177 / 309

Moving on to step 3:
177 divided by 309 is 0 with a remainder of 177.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 177, we get 177.
Grab the next digit (7) from the dividend, add it to 177, then carry on: 1777 / 309

Advancing to step 4:
309 goes into 1777 5 times with a remainder of 232.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 1545 from 1777 leaves us with 232.
Bring next digit (0) of the dividend behind the 232 and repeat the process: 2320 / 309

On to step 5:
When dividing 2320 by 309, we get 7 with a remainder of 157.
Use 7 as the next digit of our solution. 
Result so far: 57.0
The remainder is 157 after subtracting 2163 from 2320.
Fetch the next digit (4) from the dividend, attach it to 157 and continue: 1574 / 309

On to step 6:
The number 309 fits into 1574 5 times, leaving a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 575.0
Subtract 1545 from 1574 to get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 309

Advancing to step 7:
When dividing 293 by 309, we get 0 with a remainder of 293.
The next digit of our result is 0. 
Result so far: 5750.0
Subtracting 0 from 293 leaves us with 293.
Append the next digit (4) from the dividend to 293 and continue with: 2934 / 309

On to step 8:
2934 divided by 309 is 9 with a remainder of 153.
The number 9 becomes the next digit in our result. 
Result so far: 57509.0
Deduct 2781 from 2934 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Going ahead to step 9:
When dividing 1530 by 309, we get 4 with a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 57509.4
Subtracting 1236 from 1530 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 10:
309 goes into 2940 9 times with a remainder of 159.
Record the quotient 9 as the next digit in the result. 
Result so far: 57509.49
Subtract 2781 from 2940 to get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

On to step 11:
1590 divided by 309 is 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 57509.495
The remainder is 45 after subtracting 1545 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
309 can be fit into 450 1 times, resulting in a remainder of 141.
Record the quotient 1 as the next digit in the result. 
Result so far: 57509.4951
Subtracting 309 from 450 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Step 13:
309 goes into 1410 4 times with a remainder of 174.
The next digit of our result is 4. 
Result so far: 57509.49514
Subtracting 1236 from 1410 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 14:
The number 309 fits into 1740 5 times, leaving a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 57509.495145
The remainder is 195 after subtracting 1545 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 15:
The number 309 fits into 1950 6 times, leaving a remainder of 96.
The next digit of our result is 6. 
Result so far: 57509.4951456
Deduct 1854 from 1950 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 16:
If we divide 960 by 309, we get 3 and a remainder of 33.
Record the quotient 3 as the next digit in the result. 
Result so far: 57509.49514563
If we subtract 927 from 960, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Our division results in 57509.49514563 with a remaining 3.3e-08.
