86421264 divided by 618 
Let's see how many times 618 fits into 86421264.

Advancing to step 1:
The number 618 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 618

On to step 2:
618 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (4) from the dividend, add it to 86, then carry on: 864 / 618

Moving on to step 3:
When dividing 864 by 618, we get 1 with a remainder of 246.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 618 from 864, we get 246.
Include the next digit (2) from the dividend after 246, then repeat: 2462 / 618

Step 4:
The number 618 fits into 2462 3 times, leaving a remainder of 608.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1854 from 2462 to get 608.
Take the next digit (1) from the dividend and append it to 608, then repeat: 6081 / 618

Moving on to step 5:
When dividing 6081 by 618, we get 9 with a remainder of 519.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtracting 5562 from 6081 leaves us with 519.
Grab the next digit (2) from the dividend, add it to 519, then carry on: 5192 / 618

Going ahead to step 6:
618 can be fit into 5192 8 times, resulting in a remainder of 248.
Write down 8 as next digit of the result. 
Result so far: 1398.0
If we subtract 4944 from 5192, we get 248.
Fetch the next digit (6) from the dividend, attach it to 248 and continue: 2486 / 618

On to step 7:
618 goes into 2486 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 13984.0
If we subtract 2472 from 2486, we get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 618

On to step 8:
144 divided by 618 is 0 with a remainder of 144.
Record the quotient 0 as the next digit in the result. 
Result so far: 139840.0
Deduct 0 from 144 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 9:
618 goes into 1440 2 times with a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 139840.2
The remainder is 204 after subtracting 1236 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
618 can be fit into 2040 3 times, resulting in a remainder of 186.
The next digit of our result is 3. 
Result so far: 139840.23
If we take 1854 away from 2040, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 11:
When dividing 1860 by 618, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 139840.233
Subtract 1854 from 1860 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 139840.233 and a remainder of 0.0006.
