873138 ÷ 86 
Let's see how many times 86 fits into 873138.

Moving on to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 86

Moving on to step 2:
If we divide 87 by 86, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 86 from 87, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 86

Step 3:
When dividing 13 by 86, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 13, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 86

Advancing to step 4:
When dividing 131 by 86, we get 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Subtracting 86 from 131 leaves us with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 86

Going ahead to step 5:
453 divided by 86 is 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 1015.0
If we take 430 away from 453, we end up with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 86

On to step 6:
86 can be fit into 238 2 times, resulting in a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 10152.0
Subtract 172 from 238 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 7:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 10152.7
If we take 602 away from 660, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
If we divide 580 by 86, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 10152.76
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 10152.767
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
86 goes into 380 4 times with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 10152.7674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
When dividing 360 by 86, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 10152.76744
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 10152.76744 with a remaining 1.6e-05.
