80870866 divided by 385 
We want to figure out the number of times 80870866 can be divided by 385.

Step 1:
The number 385 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 385

Let's proceed to step 2:
If we divide 80 by 385, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 385

Let's proceed to step 3:
The number 385 fits into 808 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 770 from 808 leaves us with 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 385

Going ahead to step 4:
385 goes into 387 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 385 from 387 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 385

Step 5:
When dividing 20 by 385, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 210.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 385

Advancing to step 6:
The number 385 fits into 208 0 times, leaving a remainder of 208.
The next digit of our result is 0. 
Result so far: 2100.0
Subtract 0 from 208 to get 208.
Bring next digit (6) of the dividend behind the 208 and repeat the process: 2086 / 385

Advancing to step 7:
385 can be fit into 2086 5 times, resulting in a remainder of 161.
Record the quotient 5 as the next digit in the result. 
Result so far: 21005.0
Deduct 1925 from 2086 and we're left with 161.
Take the next digit (6) from the dividend and append it to 161, then repeat: 1616 / 385

Let's proceed to step 8:
When dividing 1616 by 385, we get 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 210054.0
If we take 1540 away from 1616, we end up 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.

Moving on to step 9:
The number 385 fits into 760 1 times, leaving a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 210054.1
Subtract 385 from 760 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 10:
385 goes into 3750 9 times with a remainder of 285.
Write down 9 as next digit of the result. 
Result so far: 210054.19
The remainder is 285 after subtracting 3465 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 11:
When dividing 2850 by 385, we get 7 with a remainder of 155.
Write down 7 as next digit of the result. 
Result so far: 210054.197
Subtracting 2695 from 2850 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 12:
When dividing 1550 by 385, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 210054.1974
Subtracting 1540 from 1550 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
If we divide 100 by 385, we get 0 and a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 210054.1974
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 14:
385 can be fit into 1000 2 times, resulting in a remainder of 230.
Record the quotient 2 as the next digit in the result. 
Result so far: 210054.197402
Deduct 770 from 1000 and we're left with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

On to step 15:
2300 divided by 385 is 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 210054.1974025
The remainder is 375 after subtracting 1925 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 16:
385 can be fit into 3750 9 times, resulting in a remainder of 285.
The number 9 becomes the next digit in our result. 
Result so far: 210054.19740259
Subtracting 3465 from 3750 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

The final result is 210054.19740259 with a remainder of 2.85e-07.
