867251 ÷ 86 
Let's see how many times 86 fits into 867251.

Moving on to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 86

Step 2:
86 divided by 86 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 86 from 86.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 86

Advancing to step 3:
7 divided by 86 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 86

On to step 4:
The number 86 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 72 and we're left with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 86

Going ahead to step 5:
86 can be fit into 725 8 times, resulting in a remainder of 37.
Write down 8 as next digit of the result. 
Result so far: 1008.0
Subtracting 688 from 725 leaves us with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 86

Moving on to step 6:
86 goes into 371 4 times with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 10084.0
Subtracting 344 from 371 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
86 can be fit into 270 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 10084.3
Subtracting 258 from 270 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
120 divided by 86 is 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 10084.31
Deduct 86 from 120 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
86 can be fit into 340 3 times, resulting in a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 10084.313
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 10:
The number 86 fits into 820 9 times, leaving a remainder of 46.
The next digit of our result is 9. 
Result so far: 10084.3139
Deduct 774 from 820 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.

Step 11:
When dividing 460 by 86, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 10084.31395
Deduct 430 from 460 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
When dividing 300 by 86, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 10084.313953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
If we divide 420 by 86, we get 4 and a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 10084.3139534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 14:
86 can be fit into 760 8 times, resulting in a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 10084.31395348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 10084.31395348, with a leftover of 7.2e-08.
