86299586 ÷ 574 
Our goal is to divide 86299586 by 574.

Step 1:
If we divide 8 by 574, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 574

On to step 2:
The number 574 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
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 / 574

Moving on to step 3:
574 goes into 862 1 times with a remainder of 288.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 574 from 862 to get 288.
Bring next digit (9) of the dividend behind the 288 and repeat the process: 2889 / 574

On to step 4:
If we divide 2889 by 574, we get 5 and a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 2870 from 2889, we get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 574

Advancing to step 5:
574 can be fit into 199 0 times, resulting in a remainder of 199.
The next digit of our result is 0. 
Result so far: 150.0
Subtracting 0 from 199 leaves us with 199.
Fetch the next digit (5) from the dividend, attach it to 199 and continue: 1995 / 574

On to step 6:
574 goes into 1995 3 times with a remainder of 273.
Put 3 as the next digit of the answer. 
Result so far: 1503.0
If we take 1722 away from 1995, we end up with 273.
Take the next digit (8) from the dividend and append it to 273, then repeat: 2738 / 574

Step 7:
574 can be fit into 2738 4 times, resulting in a remainder of 442.
Put 4 as the next digit of the answer. 
Result so far: 15034.0
The remainder is 442 after subtracting 2296 from 2738.
Take the next digit (6) from the dividend and append it to 442, then repeat: 4426 / 574

Advancing to step 8:
If we divide 4426 by 574, we get 7 and a remainder of 408.
Write down 7 as next digit of the result. 
Result so far: 150347.0
Deduct 4018 from 4426 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 9:
4080 divided by 574 is 7 with a remainder of 62.
The number 7 becomes the next digit in our result. 
Result so far: 150347.7
The remainder is 62 after subtracting 4018 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
When dividing 620 by 574, we get 1 with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 150347.71
Deduct 574 from 620 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
460 divided by 574 is 0 with a remainder of 460.
Put 0 as the next digit of the answer. 
Result so far: 150347.71
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 12:
574 goes into 4600 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 150347.7108
Subtract 4592 from 4600 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
574 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 150347.7108
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 14:
When dividing 800 by 574, we get 1 with a remainder of 226.
The next digit of our result is 1. 
Result so far: 150347.710801
The remainder is 226 after subtracting 574 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 15:
The number 574 fits into 2260 3 times, leaving a remainder of 538.
Put 3 as the next digit of the answer. 
Result so far: 150347.7108013
If we subtract 1722 from 2260, we get 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Advancing to step 16:
574 goes into 5380 9 times with a remainder of 214.
Record the quotient 9 as the next digit in the result. 
Result so far: 150347.71080139
Deduct 5166 from 5380 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The final result is 150347.71080139 with a remainder of 2.14e-07.
