We look at the division of 981573 by 86 
We want to divide 981573 by 86.

Step 1:
86 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 86

Going ahead to step 2:
86 can be fit into 98 1 times, resulting in a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 86 from 98 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 86

Moving on to step 3:
When dividing 121 by 86, we get 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 86 from 121 and we're left with 35.
Grab the next digit (5) from the dividend, add it to 35, then carry on: 355 / 86

Going ahead to step 4:
The number 86 fits into 355 4 times, leaving a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Subtract 344 from 355 to get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 86

Moving on to step 5:
117 divided by 86 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 1141.0
Subtract 86 from 117 to get 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 86

Moving on to step 6:
When dividing 313 by 86, we get 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 11413.0
Subtract 258 from 313 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
550 divided by 86 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 11413.6
Subtract 516 from 550 to 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.

Let's proceed to step 8:
If we divide 340 by 86, we get 3 and a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 11413.63
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 9:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 11413.639
Deduct 774 from 820 and we're left 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 10:
460 divided by 86 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 11413.6395
If we subtract 430 from 460, we 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.

Moving on to step 11:
If we divide 300 by 86, we get 3 and a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 11413.63953
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
420 divided by 86 is 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 11413.639534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
If we divide 760 by 86, we get 8 and a remainder of 72.
The next digit of our result is 8. 
Result so far: 11413.6395348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 14:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 11413.63953488
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 11413.63953488 with a remainder of 3.2e-08.
