We divide 878543 by 86
We want to figure out the number of times 878543 can be divided by 86.

Going ahead to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 86

Moving on to step 2:
If we divide 87 by 86, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 86 from 87 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 86

Going ahead to step 3:
When dividing 18 by 86, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 18 after subtracting 0 from 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 86

Let's proceed to step 4:
When dividing 185 by 86, we get 2 with a remainder of 13.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtract 172 from 185 to get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 86

Moving on to step 5:
134 divided by 86 is 1 with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 1021.0
If we take 86 away from 134, we end up with 48.
Grab the next digit (3) from the dividend, add it to 48, then carry on: 483 / 86

Moving on to step 6:
When dividing 483 by 86, we get 5 with a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 10215.0
Subtracting 430 from 483 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.

Let's proceed to step 7:
When dividing 530 by 86, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 10215.6
The remainder is 14 after subtracting 516 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
When dividing 140 by 86, we get 1 with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 10215.61
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 9:
86 can be fit into 540 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 10215.616
Deduct 516 from 540 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
The number 86 fits into 240 2 times, leaving a remainder of 68.
Put 2 as the next digit of the answer. 
Result so far: 10215.6162
Subtracting 172 from 240 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
If we divide 680 by 86, we get 7 and a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 10215.61627
If we take 602 away from 680, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 12:
780 divided by 86 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 10215.616279
Subtract 774 from 780 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
86 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 10215.616279
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
86 goes into 600 6 times with a remainder of 84.
The next digit of our result is 6. 
Result so far: 10215.61627906
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

The final result is 10215.61627906 with a remainder of 8.4e-08.
