We're dividing 997863 by 86 
We want to divide 997863 by 86.

Moving on to step 1:
The number 86 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
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

Advancing to step 2:
The number 86 fits into 99 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 13 after subtracting 86 from 99.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 86

Moving on to step 3:
86 can be fit into 137 1 times, resulting in a remainder of 51.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 86 from 137, we get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 86

Going ahead to step 4:
If we divide 518 by 86, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
If we subtract 516 from 518, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 86

Advancing to step 5:
If we divide 26 by 86, we get 0 and a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 1160.0
If we subtract 0 from 26, we get 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 86

Let's proceed to step 6:
The number 86 fits into 263 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 11603.0
Deduct 258 from 263 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 86, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 11603.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
If we divide 500 by 86, we get 5 and a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 11603.05
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.

Going ahead to step 9:
86 goes into 700 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 11603.058
If we take 688 away from 700, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
When dividing 120 by 86, we get 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 11603.0581
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
86 goes into 340 3 times with a remainder of 82.
The next digit of our result is 3. 
Result so far: 11603.05813
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 12:
820 divided by 86 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 11603.058139
Subtracting 774 from 820 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 13:
86 goes into 460 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 11603.0581395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
86 can be fit into 300 3 times, resulting in a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 11603.05813953
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 11603.05813953, with a leftover of 4.2e-08.
