We look at the division of 77443600 by 307 
Our goal is to divide 77443600 by 307.

Let's proceed to step 1:
307 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 307

Step 2:
307 can be fit into 77 0 times, resulting in a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 307

Moving on to step 3:
If we divide 774 by 307, we get 2 and a remainder of 160.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 614 away from 774, we end up with 160.
Grab the next digit (4) from the dividend, add it to 160, then carry on: 1604 / 307

Advancing to step 4:
The number 307 fits into 1604 5 times, leaving a remainder of 69.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 1535 from 1604 and we're left with 69.
Bring next digit (3) of the dividend behind the 69 and repeat the process: 693 / 307

Going ahead to step 5:
If we divide 693 by 307, we get 2 and a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 252.0
Subtract 614 from 693 to get 79.
Append the next digit (6) from the dividend to 79 and continue with: 796 / 307

Let's proceed to step 6:
When dividing 796 by 307, we get 2 with a remainder of 182.
Record the quotient 2 as the next digit in the result. 
Result so far: 2522.0
Deduct 614 from 796 and we're left with 182.
Take the next digit (0) from the dividend and append it to 182, then repeat: 1820 / 307

Let's proceed to step 7:
When dividing 1820 by 307, we get 5 with a remainder of 285.
The next digit of our result is 5. 
Result so far: 25225.0
Subtract 1535 from 1820 to get 285.
Bring next digit (0) of the dividend behind the 285 and repeat the process: 2850 / 307

On to step 8:
307 can be fit into 2850 9 times, resulting in a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 252259.0
If we subtract 2763 from 2850, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 9:
If we divide 870 by 307, we get 2 and a remainder of 256.
Record the quotient 2 as the next digit in the result. 
Result so far: 252259.2
Subtract 614 from 870 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 10:
2560 divided by 307 is 8 with a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 252259.28
Subtracting 2456 from 2560 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 11:
If we divide 1040 by 307, we get 3 and a remainder of 119.
Record the quotient 3 as the next digit in the result. 
Result so far: 252259.283
The remainder is 119 after subtracting 921 from 1040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

On to step 12:
When dividing 1190 by 307, we get 3 with a remainder of 269.
The number 3 becomes the next digit in our result. 
Result so far: 252259.2833
Subtracting 921 from 1190 leaves us with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final outcome is 252259.2833, with a leftover of 0.00269.
