78661354 divided by 307 
We want to divide 78661354 by 307.

Step 1:
307 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 307

Let's proceed to step 2:
307 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Bring next digit (6) of the dividend behind the 78 and repeat the process: 786 / 307

Going ahead to step 3:
When dividing 786 by 307, we get 2 with a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 614 from 786 leaves us with 172.
Bring next digit (6) of the dividend behind the 172 and repeat the process: 1726 / 307

Let's proceed to step 4:
If we divide 1726 by 307, we get 5 and a remainder of 191.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 1535 away from 1726, we end up with 191.
Take the next digit (1) from the dividend and append it to 191, then repeat: 1911 / 307

Advancing to step 5:
307 can be fit into 1911 6 times, resulting in a remainder of 69.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
The remainder is 69 after subtracting 1842 from 1911.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 307

On to step 6:
When dividing 693 by 307, we get 2 with a remainder of 79.
Put 2 as the next digit of the answer. 
Result so far: 2562.0
If we subtract 614 from 693, we get 79.
Include the next digit (5) from the dividend after 79, then repeat: 795 / 307

Advancing to step 7:
If we divide 795 by 307, we get 2 and a remainder of 181.
Use 2 as the next digit of our solution. 
Result so far: 25622.0
Subtract 614 from 795 to get 181.
Grab the next digit (4) from the dividend, add it to 181, then carry on: 1814 / 307

Moving on to step 8:
If we divide 1814 by 307, we get 5 and a remainder of 279.
Write down 5 as next digit of the result. 
Result so far: 256225.0
Deduct 1535 from 1814 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 9:
2790 divided by 307 is 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 256225.9
The remainder is 27 after subtracting 2763 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 10:
When dividing 270 by 307, we get 0 with a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 256225.9
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 11:
If we divide 2700 by 307, we get 8 and a remainder of 244.
The number 8 becomes the next digit in our result. 
Result so far: 256225.908
Subtract 2456 from 2700 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 12:
307 can be fit into 2440 7 times, resulting in a remainder of 291.
Use 7 as the next digit of our solution. 
Result so far: 256225.9087
If we take 2149 away from 2440, we end up 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.

Advancing to step 13:
307 goes into 2910 9 times with a remainder of 147.
Use 9 as the next digit of our solution. 
Result so far: 256225.90879
If we subtract 2763 from 2910, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 14:
307 goes into 1470 4 times with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 256225.908794
Deduct 1228 from 1470 and we're left with 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 15:
2420 divided by 307 is 7 with a remainder of 271.
Record the quotient 7 as the next digit in the result. 
Result so far: 256225.9087947
Deduct 2149 from 2420 and we're left with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 16:
307 goes into 2710 8 times with a remainder of 254.
The number 8 becomes the next digit in our result. 
Result so far: 256225.90879478
Deduct 2456 from 2710 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

After the division, we end up with 256225.90879478 and a remainder of 2.54e-07.
