86910 divided by 89 
Let's see how many times 89 fits into 86910.

Advancing to step 1:
The number 89 fits into 8 0 times, leaving 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 / 89

Going ahead to step 2:
86 divided by 89 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 89

On to step 3:
The number 89 fits into 869 9 times, leaving a remainder of 68.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 801 from 869 and we're left with 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 89

Step 4:
If we divide 681 by 89, we get 7 and a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 97.0
Subtract 623 from 681 to get 58.
Take the next digit (0) from the dividend and append it to 58, then repeat: 580 / 89

Advancing to step 5:
If we divide 580 by 89, we get 6 and a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 976.0
Subtracting 534 from 580 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 6:
89 goes into 460 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 976.5
The remainder is 15 after subtracting 445 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
The number 89 fits into 150 1 times, leaving a remainder of 61.
Put 1 as the next digit of the answer. 
Result so far: 976.51
The remainder is 61 after subtracting 89 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 8:
The number 89 fits into 610 6 times, leaving a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 976.516
If we subtract 534 from 610, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
89 goes into 760 8 times with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 976.5168
Subtract 712 from 760 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
When dividing 480 by 89, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 976.51685
The remainder is 35 after subtracting 445 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
89 can be fit into 350 3 times, resulting in a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 976.516853
If we subtract 267 from 350, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
830 divided by 89 is 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 976.5168539
If we subtract 801 from 830, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
290 divided by 89 is 3 with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 976.51685393
Deduct 267 from 290 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 976.51685393 and a remainder of 2.3e-08.
