We divide 86978280 by 852
Our goal is to divide 86978280 by 852.

Step 1:
The number 852 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 852

Let's proceed to step 2:
If we divide 86 by 852, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 852

Advancing to step 3:
If we divide 869 by 852, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we take 852 away from 869, we end up with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 852

Going ahead to step 4:
177 divided by 852 is 0 with a remainder of 177.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 177 to get 177.
Append the next digit (8) from the dividend to 177 and continue with: 1778 / 852

Let's proceed to step 5:
When dividing 1778 by 852, we get 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 102.0
If we take 1704 away from 1778, we end up with 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 852

Moving on to step 6:
742 divided by 852 is 0 with a remainder of 742.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
If we take 0 away from 742, we end up with 742.
Include the next digit (8) from the dividend after 742, then repeat: 7428 / 852

Going ahead to step 7:
852 can be fit into 7428 8 times, resulting in a remainder of 612.
The next digit of our result is 8. 
Result so far: 10208.0
The remainder is 612 after subtracting 6816 from 7428.
Include the next digit (0) from the dividend after 612, then repeat: 6120 / 852

Let's proceed to step 8:
6120 divided by 852 is 7 with a remainder of 156.
The number 7 becomes the next digit in our result. 
Result so far: 102087.0
The remainder is 156 after subtracting 5964 from 6120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 9:
852 goes into 1560 1 times with a remainder of 708.
Use 1 as the next digit of our solution. 
Result so far: 102087.1
Deduct 852 from 1560 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Step 10:
852 can be fit into 7080 8 times, resulting in a remainder of 264.
Record the quotient 8 as the next digit in the result. 
Result so far: 102087.18
Deduct 6816 from 7080 and we're left with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
2640 divided by 852 is 3 with a remainder of 84.
Put 3 as the next digit of the answer. 
Result so far: 102087.183
Deduct 2556 from 2640 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
When dividing 840 by 852, we get 0 with a remainder of 840.
Write down 0 as next digit of the result. 
Result so far: 102087.183
If we subtract 0 from 840, we get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Advancing to step 13:
The number 852 fits into 8400 9 times, leaving a remainder of 732.
Record the quotient 9 as the next digit in the result. 
Result so far: 102087.18309
The remainder is 732 after subtracting 7668 from 8400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

Step 14:
7320 divided by 852 is 8 with a remainder of 504.
Use 8 as the next digit of our solution. 
Result so far: 102087.183098
Subtract 6816 from 7320 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 15:
The number 852 fits into 5040 5 times, leaving a remainder of 780.
Use 5 as the next digit of our solution. 
Result so far: 102087.1830985
If we subtract 4260 from 5040, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Step 16:
The number 852 fits into 7800 9 times, leaving a remainder of 132.
Use 9 as the next digit of our solution. 
Result so far: 102087.18309859
If we take 7668 away from 7800, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

The final result is 102087.18309859 with a remainder of 1.32e-07.
