We look at the division of 86212661 by 599 
We're looking to find how many times 599 goes into 86212661.

On to step 1:
When dividing 8 by 599, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 599

Advancing to step 2:
If we divide 86 by 599, we get 0 and a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (2) from the dividend to 86 and continue with: 862 / 599

Moving on to step 3:
599 goes into 862 1 times with a remainder of 263.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 599 from 862 to get 263.
Take the next digit (1) from the dividend and append it to 263, then repeat: 2631 / 599

Moving on to step 4:
When dividing 2631 by 599, we get 4 with a remainder of 235.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 235 after subtracting 2396 from 2631.
Fetch the next digit (2) from the dividend, attach it to 235 and continue: 2352 / 599

On to step 5:
2352 divided by 599 is 3 with a remainder of 555.
The next digit of our result is 3. 
Result so far: 143.0
Deduct 1797 from 2352 and we're left with 555.
Append the next digit (6) from the dividend to 555 and continue with: 5556 / 599

Moving on to step 6:
599 goes into 5556 9 times with a remainder of 165.
The number 9 becomes the next digit in our result. 
Result so far: 1439.0
Subtract 5391 from 5556 to get 165.
Append the next digit (6) from the dividend to 165 and continue with: 1656 / 599

Going ahead to step 7:
599 can be fit into 1656 2 times, resulting in a remainder of 458.
Record the quotient 2 as the next digit in the result. 
Result so far: 14392.0
Subtracting 1198 from 1656 leaves us with 458.
Append the next digit (1) from the dividend to 458 and continue with: 4581 / 599

Step 8:
599 goes into 4581 7 times with a remainder of 388.
Write down 7 as next digit of the result. 
Result so far: 143927.0
If we take 4193 away from 4581, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Moving on to step 9:
599 can be fit into 3880 6 times, resulting in a remainder of 286.
The next digit of our result is 6. 
Result so far: 143927.6
Subtract 3594 from 3880 to get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 10:
599 goes into 2860 4 times with a remainder of 464.
Record the quotient 4 as the next digit in the result. 
Result so far: 143927.64
Subtracting 2396 from 2860 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

On to step 11:
If we divide 4640 by 599, we get 7 and a remainder of 447.
Record the quotient 7 as the next digit in the result. 
Result so far: 143927.647
Subtract 4193 from 4640 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 12:
If we divide 4470 by 599, we get 7 and a remainder of 277.
The number 7 becomes the next digit in our result. 
Result so far: 143927.6477
Subtracting 4193 from 4470 leaves us with 277.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2770, and continue the process.

The quotient of the division is 143927.6477, and the remainder is 0.00277.
