86514091 ÷ 357 
We want to divide 86514091 by 357.

Moving on to step 1:
8 divided by 357 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 357

Step 2:
86 divided by 357 is 0 with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Append the next digit (5) from the dividend to 86 and continue with: 865 / 357

Moving on to step 3:
The number 357 fits into 865 2 times, leaving a remainder of 151.
The next digit of our result is 2. 
Result so far: 2.0
If we take 714 away from 865, we end up with 151.
Fetch the next digit (1) from the dividend, attach it to 151 and continue: 1511 / 357

On to step 4:
The number 357 fits into 1511 4 times, leaving a remainder of 83.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 1428 from 1511, we get 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 357

Moving on to step 5:
The number 357 fits into 834 2 times, leaving a remainder of 120.
Use 2 as the next digit of our solution. 
Result so far: 242.0
If we take 714 away from 834, we end up with 120.
Fetch the next digit (0) from the dividend, attach it to 120 and continue: 1200 / 357

Step 6:
357 goes into 1200 3 times with a remainder of 129.
Write down 3 as next digit of the result. 
Result so far: 2423.0
If we subtract 1071 from 1200, we get 129.
Fetch the next digit (9) from the dividend, attach it to 129 and continue: 1299 / 357

Advancing to step 7:
If we divide 1299 by 357, we get 3 and a remainder of 228.
Record the quotient 3 as the next digit in the result. 
Result so far: 24233.0
If we take 1071 away from 1299, we end up with 228.
Grab the next digit (1) from the dividend, add it to 228, then carry on: 2281 / 357

On to step 8:
The number 357 fits into 2281 6 times, leaving a remainder of 139.
The number 6 becomes the next digit in our result. 
Result so far: 242336.0
If we take 2142 away from 2281, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Advancing to step 9:
If we divide 1390 by 357, we get 3 and a remainder of 319.
The next digit of our result is 3. 
Result so far: 242336.3
If we subtract 1071 from 1390, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Going ahead to step 10:
When dividing 3190 by 357, we get 8 with a remainder of 334.
Record the quotient 8 as the next digit in the result. 
Result so far: 242336.38
Subtracting 2856 from 3190 leaves us with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 11:
3340 divided by 357 is 9 with a remainder of 127.
Use 9 as the next digit of our solution. 
Result so far: 242336.389
Deduct 3213 from 3340 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 12:
357 goes into 1270 3 times with a remainder of 199.
Use 3 as the next digit of our solution. 
Result so far: 242336.3893
Subtract 1071 from 1270 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 13:
When dividing 1990 by 357, we get 5 with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 242336.38935
If we subtract 1785 from 1990, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 14:
357 goes into 2050 5 times with a remainder of 265.
Use 5 as the next digit of our solution. 
Result so far: 242336.389355
The remainder is 265 after subtracting 1785 from 2050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final result is 242336.389355 with a remainder of 2.65e-05.
