984290 divided by 86 
We're looking to find how many times 86 goes into 984290.

Step 1:
9 divided by 86 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 86

Moving on to step 2:
86 goes into 98 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 12 after subtracting 86 from 98.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 86

Advancing to step 3:
124 divided by 86 is 1 with a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 86 from 124 and we're left with 38.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 86

On to step 4:
The number 86 fits into 382 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 114.0
If we subtract 344 from 382, we get 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 86

On to step 5:
389 divided by 86 is 4 with a remainder of 45.
Use 4 as the next digit of our solution. 
Result so far: 1144.0
Subtracting 344 from 389 leaves us with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 86

Advancing to step 6:
The number 86 fits into 450 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 11445.0
Subtract 430 from 450 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
86 can be fit into 200 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 11445.2
If we subtract 172 from 200, we get 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 8:
The number 86 fits into 280 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 11445.23
If we subtract 258 from 280, we 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.

On to step 9:
86 goes into 220 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 11445.232
The remainder is 48 after subtracting 172 from 220.
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 10:
If we divide 480 by 86, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 11445.2325
Subtracting 430 from 480 leaves us with 50.
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 11:
When dividing 500 by 86, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 11445.23255
If we subtract 430 from 500, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 11445.23255 with a remaining 7e-05.
