When dividing 86 by 93, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (3) from the dividend and append it to 86, then repeat: 863 / 93

Advancing to step 3:
When dividing 863 by 93, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 837 away from 863, we end up with 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 93

On to step 4:
When dividing 269 by 93, we get 2 with a remainder of 83.
The next digit of our result is 2. 
Result so far: 92.0
The remainder is 83 after subtracting 186 from 269.
Append the next digit (3) from the dividend to 83 and continue with: 833 / 93

Advancing to step 5:
When dividing 833 by 93, we get 8 with a remainder of 89.
Put 8 as the next digit of the answer. 
Result so far: 928.0
Deduct 744 from 833 and we're left with 89.
Include the next digit (7) from the dividend after 89, then repeat: 897 / 93

On to step 6:
The number 93 fits into 897 9 times, leaving a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 9289.0
Subtract 837 from 897 to get 60.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 93

On to step 7:
When dividing 607 by 93, we get 6 with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 92896.0
Subtract 558 from 607 to get 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 93

On to step 8:
The number 93 fits into 491 5 times, leaving a remainder of 26.
The next digit of our result is 5. 
Result so far: 928965.0
Deduct 465 from 491 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
260 divided by 93 is 2 with a remainder of 74.
Use 2 as the next digit of our solution. 
Result so far: 928965.2
Subtracting 186 from 260 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 10:
740 divided by 93 is 7 with a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 928965.27
Subtract 651 from 740 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 11:
93 goes into 890 9 times with a remainder of 53.
The next digit of our result is 9. 
Result so far: 928965.279
Subtracting 837 from 890 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 12:
93 goes into 530 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 928965.2795
Deduct 465 from 530 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 13:
If we divide 650 by 93, we get 6 and a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 928965.27956
The remainder is 92 after subtracting 558 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 14:
When dividing 920 by 93, we get 9 with a remainder of 83.
The next digit of our result is 9. 
Result so far: 928965.279569
If we subtract 837 from 920, 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.

On to step 15:
If we divide 830 by 93, we get 8 and a remainder of 86.
The number 8 becomes the next digit in our result. 
Result so far: 928965.2795698
If we take 744 away from 830, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 16:
When dividing 860 by 93, we get 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 928965.27956989
Deduct 837 from 860 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.

The quotient of the division is 928965.27956989, and the remainder is 2.3e-08.
