86785413 ÷ 357 
We want to divide 86785413 by 357.

Advancing to step 1:
When dividing 8 by 357, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 357

On to step 2:
86 divided by 357 is 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 357

Moving on to step 3:
357 can be fit into 867 2 times, resulting in a remainder of 153.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 714 away from 867, we end up with 153.
Bring next digit (8) of the dividend behind the 153 and repeat the process: 1538 / 357

Step 4:
When dividing 1538 by 357, we get 4 with a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 1428 from 1538, we get 110.
Append the next digit (5) from the dividend to 110 and continue with: 1105 / 357

Let's proceed to step 5:
If we divide 1105 by 357, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 243.0
If we take 1071 away from 1105, we end up with 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 357

Going ahead to step 6:
The number 357 fits into 344 0 times, leaving a remainder of 344.
The next digit of our result is 0. 
Result so far: 2430.0
The remainder is 344 after subtracting 0 from 344.
Grab the next digit (1) from the dividend, add it to 344, then carry on: 3441 / 357

Going ahead to step 7:
357 goes into 3441 9 times with a remainder of 228.
Write down 9 as next digit of the result. 
Result so far: 24309.0
Subtracting 3213 from 3441 leaves us with 228.
Include the next digit (3) from the dividend after 228, then repeat: 2283 / 357

On to step 8:
357 can be fit into 2283 6 times, resulting in a remainder of 141.
Write down 6 as next digit of the result. 
Result so far: 243096.0
Subtracting 2142 from 2283 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Going ahead to step 9:
1410 divided by 357 is 3 with a remainder of 339.
The next digit of our result is 3. 
Result so far: 243096.3
Subtracting 1071 from 1410 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Moving on to step 10:
3390 divided by 357 is 9 with a remainder of 177.
Write down 9 as next digit of the result. 
Result so far: 243096.39
Subtracting 3213 from 3390 leaves us with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 11:
357 goes into 1770 4 times with a remainder of 342.
Use 4 as the next digit of our solution. 
Result so far: 243096.394
Subtracting 1428 from 1770 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Going ahead to step 12:
If we divide 3420 by 357, we get 9 and a remainder of 207.
Record the quotient 9 as the next digit in the result. 
Result so far: 243096.3949
The remainder is 207 after subtracting 3213 from 3420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 13:
If we divide 2070 by 357, we get 5 and a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 243096.39495
The remainder is 285 after subtracting 1785 from 2070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 14:
2850 divided by 357 is 7 with a remainder of 351.
Put 7 as the next digit of the answer. 
Result so far: 243096.394957
If we take 2499 away from 2850, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 15:
357 can be fit into 3510 9 times, resulting in a remainder of 297.
The number 9 becomes the next digit in our result. 
Result so far: 243096.3949579
Subtracting 3213 from 3510 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Advancing to step 16:
2970 divided by 357 is 8 with a remainder of 114.
Write down 8 as next digit of the result. 
Result so far: 243096.39495798
Subtract 2856 from 2970 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

In conclusion, the division gives 243096.39495798 with a balance of 1.14e-07.
