64741598 ÷ 309 
Let's see how many times 309 fits into 64741598.

Going ahead to step 1:
309 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 309

Let's proceed to step 2:
When dividing 64 by 309, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 309

Moving on to step 3:
309 goes into 647 2 times with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 618 from 647 and we're left with 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 309

On to step 4:
If we divide 294 by 309, we get 0 and a remainder of 294.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Deduct 0 from 294 and we're left with 294.
Fetch the next digit (1) from the dividend, attach it to 294 and continue: 2941 / 309

Moving on to step 5:
309 goes into 2941 9 times with a remainder of 160.
The next digit of our result is 9. 
Result so far: 209.0
Subtracting 2781 from 2941 leaves us with 160.
Fetch the next digit (5) from the dividend, attach it to 160 and continue: 1605 / 309

On to step 6:
When dividing 1605 by 309, we get 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 2095.0
The remainder is 60 after subtracting 1545 from 1605.
Include the next digit (9) from the dividend after 60, then repeat: 609 / 309

Moving on to step 7:
609 divided by 309 is 1 with a remainder of 300.
Record the quotient 1 as the next digit in the result. 
Result so far: 20951.0
If we take 309 away from 609, we end up with 300.
Take the next digit (8) from the dividend and append it to 300, then repeat: 3008 / 309

Advancing to step 8:
309 goes into 3008 9 times with a remainder of 227.
The next digit of our result is 9. 
Result so far: 209519.0
The remainder is 227 after subtracting 2781 from 3008.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Step 9:
If we divide 2270 by 309, we get 7 and a remainder of 107.
Put 7 as the next digit of the answer. 
Result so far: 209519.7
The remainder is 107 after subtracting 2163 from 2270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 10:
309 can be fit into 1070 3 times, resulting in a remainder of 143.
Use 3 as the next digit of our solution. 
Result so far: 209519.73
Subtract 927 from 1070 to get 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 11:
If we divide 1430 by 309, we get 4 and a remainder of 194.
Put 4 as the next digit of the answer. 
Result so far: 209519.734
Subtract 1236 from 1430 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 12:
If we divide 1940 by 309, we get 6 and a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 209519.7346
If we take 1854 away from 1940, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 13:
The number 309 fits into 860 2 times, leaving a remainder of 242.
Write down 2 as next digit of the result. 
Result so far: 209519.73462
If we subtract 618 from 860, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 14:
The number 309 fits into 2420 7 times, leaving a remainder of 257.
Put 7 as the next digit of the answer. 
Result so far: 209519.734627
Subtract 2163 from 2420 to get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 15:
If we divide 2570 by 309, we get 8 and a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 209519.7346278
Subtracting 2472 from 2570 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 16:
309 goes into 980 3 times with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 209519.73462783
If we take 927 away from 980, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 209519.73462783, and the remainder is 5.3e-08.
