86600340 ÷ 579 
Our goal is to divide 86600340 by 579.

Going ahead to step 1:
If we divide 8 by 579, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
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 / 579

Advancing to step 2:
579 goes into 86 0 times with 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.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 579

Step 3:
866 divided by 579 is 1 with a remainder of 287.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 579 from 866 to get 287.
Bring next digit (0) of the dividend behind the 287 and repeat the process: 2870 / 579

Let's proceed to step 4:
When dividing 2870 by 579, we get 4 with a remainder of 554.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2316 from 2870 and we're left with 554.
Append the next digit (0) from the dividend to 554 and continue with: 5540 / 579

Let's proceed to step 5:
5540 divided by 579 is 9 with a remainder of 329.
Write down 9 as next digit of the result. 
Result so far: 149.0
If we take 5211 away from 5540, we end up with 329.
Take the next digit (3) from the dividend and append it to 329, then repeat: 3293 / 579

Moving on to step 6:
579 goes into 3293 5 times with a remainder of 398.
The next digit of our result is 5. 
Result so far: 1495.0
Subtract 2895 from 3293 to get 398.
Take the next digit (4) from the dividend and append it to 398, then repeat: 3984 / 579

Let's proceed to step 7:
If we divide 3984 by 579, we get 6 and a remainder of 510.
Put 6 as the next digit of the answer. 
Result so far: 14956.0
If we take 3474 away from 3984, we end up with 510.
Take the next digit (0) from the dividend and append it to 510, then repeat: 5100 / 579

On to step 8:
If we divide 5100 by 579, we get 8 and a remainder of 468.
Write down 8 as next digit of the result. 
Result so far: 149568.0
Subtracting 4632 from 5100 leaves us with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 9:
When dividing 4680 by 579, we get 8 with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 149568.8
The remainder is 48 after subtracting 4632 from 4680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
579 can be fit into 480 0 times, resulting in a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 149568.8
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 11:
When dividing 4800 by 579, we get 8 with a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 149568.808
If we take 4632 away from 4800, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 12:
If we divide 1680 by 579, we get 2 and a remainder of 522.
Record the quotient 2 as the next digit in the result. 
Result so far: 149568.8082
Deduct 1158 from 1680 and we're left with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 13:
5220 divided by 579 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 149568.80829
Subtracting 5211 from 5220 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 14:
When dividing 90 by 579, we get 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 149568.80829
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 15:
900 divided by 579 is 1 with a remainder of 321.
Record the quotient 1 as the next digit in the result. 
Result so far: 149568.8082901
If we subtract 579 from 900, we get 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 16:
579 goes into 3210 5 times with a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 149568.80829015
If we take 2895 away from 3210, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The quotient of the division is 149568.80829015, and the remainder is 3.15e-07.
