Let's divide 869748 by 86
Let's see how many times 86 fits into 869748.

Moving on to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 86

Step 2:
If we divide 86 by 86, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 86 away from 86, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 86

On to step 3:
86 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 9, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 86

Moving on to step 4:
86 goes into 97 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 86 from 97 leaves us with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 86

Going ahead to step 5:
86 goes into 114 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1011.0
Subtracting 86 from 114 leaves us with 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 86

Advancing to step 6:
86 can be fit into 288 3 times, resulting in a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 10113.0
The remainder is 30 after subtracting 258 from 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 10113.3
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
If we divide 420 by 86, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 10113.34
The remainder is 76 after subtracting 344 from 420.
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 9:
The number 86 fits into 760 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 10113.348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
When dividing 720 by 86, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 10113.3488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 10113.3488 and a remainder of 0.00032.
