We're dividing 990854 by 86 
Let's see how many times 86 fits into 990854.

Let's proceed to step 1:
86 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 86

Advancing to step 2:
The number 86 fits into 99 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 86 from 99 leaves us with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 86

Going ahead to step 3:
When dividing 130 by 86, we get 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 44 after subtracting 86 from 130.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 86

Advancing to step 4:
If we divide 448 by 86, we get 5 and a remainder of 18.
The next digit of our result is 5. 
Result so far: 115.0
The remainder is 18 after subtracting 430 from 448.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 86

Advancing to step 5:
The number 86 fits into 185 2 times, leaving a remainder of 13.
The next digit of our result is 2. 
Result so far: 1152.0
Subtract 172 from 185 to get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 86

Going ahead to step 6:
86 can be fit into 134 1 times, resulting in a remainder of 48.
The next digit of our result is 1. 
Result so far: 11521.0
If we take 86 away from 134, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
When dividing 480 by 86, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11521.5
The remainder is 50 after subtracting 430 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
86 goes into 500 5 times with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 11521.55
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 11521.55 with a balance of 0.07.
