We divide 86087172 by 859
We want to divide 86087172 by 859.

Moving on to step 1:
8 divided by 859 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 859

On to step 2:
86 divided by 859 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (0) from the dividend and append it to 86, then repeat: 860 / 859

Going ahead to step 3:
859 goes into 860 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 859 from 860, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 859

Moving on to step 4:
When dividing 18 by 859, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 18, we get 18.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 859

Advancing to step 5:
If we divide 187 by 859, we get 0 and a remainder of 187.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtracting 0 from 187 leaves us with 187.
Bring next digit (1) of the dividend behind the 187 and repeat the process: 1871 / 859

Moving on to step 6:
1871 divided by 859 is 2 with a remainder of 153.
Record the quotient 2 as the next digit in the result. 
Result so far: 1002.0
If we take 1718 away from 1871, we end up with 153.
Bring next digit (7) of the dividend behind the 153 and repeat the process: 1537 / 859

Going ahead to step 7:
If we divide 1537 by 859, we get 1 and a remainder of 678.
The number 1 becomes the next digit in our result. 
Result so far: 10021.0
If we take 859 away from 1537, we end up with 678.
Append the next digit (2) from the dividend to 678 and continue with: 6782 / 859

Let's proceed to step 8:
If we divide 6782 by 859, we get 7 and a remainder of 769.
The number 7 becomes the next digit in our result. 
Result so far: 100217.0
If we take 6013 away from 6782, we end up with 769.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Let's proceed to step 9:
7690 divided by 859 is 8 with a remainder of 818.
Record the quotient 8 as the next digit in the result. 
Result so far: 100217.8
Deduct 6872 from 7690 and we're left with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

Let's proceed to step 10:
8180 divided by 859 is 9 with a remainder of 449.
The next digit of our result is 9. 
Result so far: 100217.89
If we take 7731 away from 8180, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Moving on to step 11:
If we divide 4490 by 859, we get 5 and a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 100217.895
If we take 4295 away from 4490, we end up with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 12:
When dividing 1950 by 859, we get 2 with a remainder of 232.
Record the quotient 2 as the next digit in the result. 
Result so far: 100217.8952
The remainder is 232 after subtracting 1718 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 13:
The number 859 fits into 2320 2 times, leaving a remainder of 602.
Use 2 as the next digit of our solution. 
Result so far: 100217.89522
Subtracting 1718 from 2320 leaves us with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

After the division, we end up with 100217.89522 and a remainder of 0.000602.
