Let's divide 866362 by 89
We're looking to find how many times 89 goes into 866362.

Advancing to step 1:
89 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 89

Going ahead to step 2:
86 divided by 89 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 89

Going ahead to step 3:
If we divide 866 by 89, we get 9 and a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 801 from 866 leaves us with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 89

Moving on to step 4:
If we divide 653 by 89, we get 7 and a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 623 from 653 leaves us with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 89

Moving on to step 5:
The number 89 fits into 306 3 times, leaving a remainder of 39.
The next digit of our result is 3. 
Result so far: 973.0
Subtracting 267 from 306 leaves us with 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 89

Step 6:
89 can be fit into 392 4 times, resulting in a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 9734.0
Deduct 356 from 392 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 89 fits into 360 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 9734.4
Subtracting 356 from 360 leaves us 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.

Moving on to step 8:
When dividing 40 by 89, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9734.4
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 89, we get 4 and a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 9734.404
If we take 356 away from 400, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
If we divide 440 by 89, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 9734.4044
If we take 356 away from 440, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 9734.4044 with a remaining 0.00084.
