86540690 divided by 307 
We want to figure out the number of times 86540690 can be divided by 307.

Step 1:
If we divide 8 by 307, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 307

Let's proceed to step 2:
86 divided by 307 is 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 307

Moving on to step 3:
307 goes into 865 2 times with a remainder of 251.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 614 from 865, we get 251.
Fetch the next digit (4) from the dividend, attach it to 251 and continue: 2514 / 307

Advancing to step 4:
2514 divided by 307 is 8 with a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 2456 from 2514, we get 58.
Fetch the next digit (0) from the dividend, attach it to 58 and continue: 580 / 307

Advancing to step 5:
If we divide 580 by 307, we get 1 and a remainder of 273.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
If we take 307 away from 580, we end up with 273.
Take the next digit (6) from the dividend and append it to 273, then repeat: 2736 / 307

Moving on to step 6:
When dividing 2736 by 307, we get 8 with a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 2818.0
The remainder is 280 after subtracting 2456 from 2736.
Grab the next digit (9) from the dividend, add it to 280, then carry on: 2809 / 307

Advancing to step 7:
307 can be fit into 2809 9 times, resulting in a remainder of 46.
The next digit of our result is 9. 
Result so far: 28189.0
Subtract 2763 from 2809 to get 46.
Fetch the next digit (0) from the dividend, attach it to 46 and continue: 460 / 307

Going ahead to step 8:
When dividing 460 by 307, we get 1 with a remainder of 153.
Record the quotient 1 as the next digit in the result. 
Result so far: 281891.0
If we take 307 away from 460, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Step 9:
When dividing 1530 by 307, we get 4 with a remainder of 302.
Use 4 as the next digit of our solution. 
Result so far: 281891.4
The remainder is 302 after subtracting 1228 from 1530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 10:
The number 307 fits into 3020 9 times, leaving a remainder of 257.
Use 9 as the next digit of our solution. 
Result so far: 281891.49
Subtracting 2763 from 3020 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 11:
When dividing 2570 by 307, we get 8 with a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 281891.498
If we take 2456 away from 2570, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 12:
307 goes into 1140 3 times with a remainder of 219.
Write down 3 as next digit of the result. 
Result so far: 281891.4983
Subtract 921 from 1140 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 13:
2190 divided by 307 is 7 with a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 281891.49837
If we subtract 2149 from 2190, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 14:
307 goes into 410 1 times with a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 281891.498371
If we subtract 307 from 410, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 15:
307 goes into 1030 3 times with a remainder of 109.
The number 3 becomes the next digit in our result. 
Result so far: 281891.4983713
Subtract 921 from 1030 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Advancing to step 16:
The number 307 fits into 1090 3 times, leaving a remainder of 169.
The next digit of our result is 3. 
Result so far: 281891.49837133
Subtract 921 from 1090 to get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

After the division, we end up with 281891.49837133 and a remainder of 1.69e-07.
