77141512 ÷ 307 
We want to divide 77141512 by 307.

Advancing to step 1:
7 divided by 307 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 307

Going ahead to step 2:
When dividing 77 by 307, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 307

Advancing to step 3:
307 goes into 771 2 times with a remainder of 157.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 614 from 771 leaves us with 157.
Fetch the next digit (4) from the dividend, attach it to 157 and continue: 1574 / 307

Advancing to step 4:
307 can be fit into 1574 5 times, resulting in a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 1535 from 1574 leaves us with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 307

On to step 5:
When dividing 391 by 307, we get 1 with a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 251.0
Subtracting 307 from 391 leaves us with 84.
Grab the next digit (5) from the dividend, add it to 84, then carry on: 845 / 307

Going ahead to step 6:
845 divided by 307 is 2 with a remainder of 231.
The next digit of our result is 2. 
Result so far: 2512.0
If we subtract 614 from 845, we get 231.
Include the next digit (1) from the dividend after 231, then repeat: 2311 / 307

Moving on to step 7:
307 can be fit into 2311 7 times, resulting in a remainder of 162.
Put 7 as the next digit of the answer. 
Result so far: 25127.0
Subtract 2149 from 2311 to get 162.
Grab the next digit (2) from the dividend, add it to 162, then carry on: 1622 / 307

Let's proceed to step 8:
When dividing 1622 by 307, we get 5 with a remainder of 87.
Record the quotient 5 as the next digit in the result. 
Result so far: 251275.0
If we take 1535 away from 1622, we end up with 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.
Write down 2 as next digit of the result. 
Result so far: 251275.2
If we subtract 614 from 870, we 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.

Going ahead to step 10:
307 can be fit into 2560 8 times, resulting in a remainder of 104.
Record the quotient 8 as the next digit in the result. 
Result so far: 251275.28
If we take 2456 away from 2560, we end up 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:
307 goes into 1040 3 times with a remainder of 119.
Write down 3 as next digit of the result. 
Result so far: 251275.283
If we take 921 away from 1040, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Going ahead to step 12:
307 can be fit into 1190 3 times, resulting in a remainder of 269.
The next digit of our result is 3. 
Result so far: 251275.2833
Subtract 921 from 1190 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Our division results in 251275.2833 with a remaining 0.00269.
