We divide 87855730 by 86
Let's see how many times 86 fits into 87855730.

Moving on to step 1:
The number 86 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
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 86

On to step 2:
86 can be fit into 87 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 86 from 87 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 86

Advancing to step 3:
The number 86 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 86

Step 4:
86 goes into 185 2 times with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Deduct 172 from 185 and we're left with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 86

Advancing to step 5:
135 divided by 86 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1021.0
Deduct 86 from 135 and we're left with 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 86

Let's proceed to step 6:
86 goes into 497 5 times with a remainder of 67.
The number 5 becomes the next digit in our result. 
Result so far: 10215.0
If we subtract 430 from 497, we get 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 86

Let's proceed to step 7:
If we divide 673 by 86, we get 7 and a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 102157.0
If we take 602 away from 673, we end up with 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 86

Let's proceed to step 8:
When dividing 710 by 86, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 1021578.0
The remainder is 22 after subtracting 688 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
86 goes into 220 2 times with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 1021578.2
The remainder is 48 after subtracting 172 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
86 goes into 480 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 1021578.25
Deduct 430 from 480 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
500 divided by 86 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1021578.255
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 1021578.255, with a leftover of 0.007.
