75513426 ÷ 309 
Let's see how many times 309 fits into 75513426.

Step 1:
7 divided by 309 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 309

Moving on to step 2:
309 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Take the next digit (5) from the dividend and append it to 75, then repeat: 755 / 309

Let's proceed to step 3:
The number 309 fits into 755 2 times, leaving a remainder of 137.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 618 from 755 leaves us with 137.
Bring next digit (1) of the dividend behind the 137 and repeat the process: 1371 / 309

Going ahead to step 4:
If we divide 1371 by 309, we get 4 and a remainder of 135.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 1236 from 1371 and we're left with 135.
Grab the next digit (3) from the dividend, add it to 135, then carry on: 1353 / 309

Let's proceed to step 5:
1353 divided by 309 is 4 with a remainder of 117.
Write down 4 as next digit of the result. 
Result so far: 244.0
Subtract 1236 from 1353 to get 117.
Include the next digit (4) from the dividend after 117, then repeat: 1174 / 309

Advancing to step 6:
309 goes into 1174 3 times with a remainder of 247.
The next digit of our result is 3. 
Result so far: 2443.0
Subtract 927 from 1174 to get 247.
Grab the next digit (2) from the dividend, add it to 247, then carry on: 2472 / 309

Advancing to step 7:
309 can be fit into 2472 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 24438.0
Deduct 2472 from 2472 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 309

Let's proceed to step 8:
6 divided by 309 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 244380.0
If we take 0 away from 6, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
If we divide 60 by 309, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 244380.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 10:
309 can be fit into 600 1 times, resulting in a remainder of 291.
Record the quotient 1 as the next digit in the result. 
Result so far: 244380.01
Deduct 309 from 600 and we're left with 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

On to step 11:
The number 309 fits into 2910 9 times, leaving a remainder of 129.
Write down 9 as next digit of the result. 
Result so far: 244380.019
Deduct 2781 from 2910 and we're left with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Advancing to step 12:
When dividing 1290 by 309, we get 4 with a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 244380.0194
The remainder is 54 after subtracting 1236 from 1290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
309 can be fit into 540 1 times, resulting in a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 244380.01941
If we subtract 309 from 540, we get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Going ahead to step 14:
The number 309 fits into 2310 7 times, leaving a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 244380.019417
If we take 2163 away from 2310, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Let's proceed to step 15:
When dividing 1470 by 309, we get 4 with a remainder of 234.
Write down 4 as next digit of the result. 
Result so far: 244380.0194174
Subtracting 1236 from 1470 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 16:
When dividing 2340 by 309, we get 7 with a remainder of 177.
The next digit of our result is 7. 
Result so far: 244380.01941747
Subtract 2163 from 2340 to get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

The quotient of the division is 244380.01941747, and the remainder is 1.77e-07.
