We look at the division of 870152 by 86 
Our goal is to divide 870152 by 86.

Let's proceed 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.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 86

Step 2:
87 divided by 86 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 86 from 87 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 86

Let's proceed to step 3:
10 divided by 86 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 10, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 86

Step 4:
86 goes into 101 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 101.0
The remainder is 15 after subtracting 86 from 101.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 86

Let's proceed to step 5:
When dividing 155 by 86, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 1011.0
Deduct 86 from 155 and we're left with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 86

Going ahead to step 6:
692 divided by 86 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 10118.0
If we take 688 away from 692, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 86, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10118.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
400 divided by 86 is 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 10118.04
Subtracting 344 from 400 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
86 goes into 560 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 10118.046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 10:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 10118.0465
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 86, we get 1 and a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 10118.04651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
140 divided by 86 is 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 10118.046511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 10118.046511, with a leftover of 5.4e-06.
