We look at the division of 86286778 by 601 
Let's see how many times 601 fits into 86286778.

Step 1:
601 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 601

Advancing to step 2:
If we divide 86 by 601, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Grab the next digit (2) from the dividend, add it to 86, then carry on: 862 / 601

Advancing to step 3:
When dividing 862 by 601, we get 1 with a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 601 away from 862, we end up with 261.
Include the next digit (8) from the dividend after 261, then repeat: 2618 / 601

Let's proceed to step 4:
2618 divided by 601 is 4 with a remainder of 214.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2404 from 2618 and we're left with 214.
Bring next digit (6) of the dividend behind the 214 and repeat the process: 2146 / 601

Moving on to step 5:
2146 divided by 601 is 3 with a remainder of 343.
The next digit of our result is 3. 
Result so far: 143.0
Subtracting 1803 from 2146 leaves us with 343.
Append the next digit (7) from the dividend to 343 and continue with: 3437 / 601

Going ahead to step 6:
The number 601 fits into 3437 5 times, leaving a remainder of 432.
Record the quotient 5 as the next digit in the result. 
Result so far: 1435.0
Subtracting 3005 from 3437 leaves us with 432.
Include the next digit (7) from the dividend after 432, then repeat: 4327 / 601

Step 7:
The number 601 fits into 4327 7 times, leaving a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 14357.0
If we subtract 4207 from 4327, we get 120.
Take the next digit (8) from the dividend and append it to 120, then repeat: 1208 / 601

Advancing to step 8:
If we divide 1208 by 601, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 143572.0
Subtracting 1202 from 1208 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
601 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 143572.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
The number 601 fits into 600 0 times, leaving a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 143572.0
Subtracting 0 from 600 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

After the division, we end up with 143572.0 and a remainder of 0.6.
