990609 divided by 86 
We're looking to find how many times 86 goes into 990609.

Let's proceed to step 1:
If we divide 9 by 86, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 86

On to step 2:
99 divided by 86 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 86 from 99, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 86

Step 3:
130 divided by 86 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 86 away from 130, we end up with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 86

On to step 4:
86 can be fit into 446 5 times, resulting in a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Deduct 430 from 446 and we're left with 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 86

Advancing to step 5:
The number 86 fits into 160 1 times, leaving a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 1151.0
Subtract 86 from 160 to get 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 86

Advancing to step 6:
The number 86 fits into 749 8 times, leaving a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 11518.0
Subtracting 688 from 749 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 7:
When dividing 610 by 86, we get 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 11518.7
If we take 602 away from 610, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 86, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 11518.7
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
The number 86 fits into 800 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 11518.709
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
86 goes into 260 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 11518.7093
Subtract 258 from 260 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
20 divided by 86 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11518.7093
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
If we divide 200 by 86, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 11518.709302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
280 divided by 86 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 11518.7093023
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
86 goes into 220 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 11518.70930232
Deduct 172 from 220 and we're left 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.

The final outcome is 11518.70930232, with a leftover of 4.8e-08.
