80030835 ÷ 855 
We want to figure out the number of times 80030835 can be divided by 855.

Step 1:
855 goes into 8 0 times with 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.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 855

Moving on to step 2:
The number 855 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (0) from the dividend to 80 and continue with: 800 / 855

Advancing to step 3:
The number 855 fits into 800 0 times, leaving a remainder of 800.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 800 and we're left with 800.
Bring next digit (3) of the dividend behind the 800 and repeat the process: 8003 / 855

On to step 4:
If we divide 8003 by 855, we get 9 and a remainder of 308.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 7695 from 8003 leaves us with 308.
Include the next digit (0) from the dividend after 308, then repeat: 3080 / 855

Step 5:
When dividing 3080 by 855, we get 3 with a remainder of 515.
The next digit of our result is 3. 
Result so far: 93.0
Subtracting 2565 from 3080 leaves us with 515.
Fetch the next digit (8) from the dividend, attach it to 515 and continue: 5158 / 855

On to step 6:
855 can be fit into 5158 6 times, resulting in a remainder of 28.
The next digit of our result is 6. 
Result so far: 936.0
Subtract 5130 from 5158 to get 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 855

Let's proceed to step 7:
When dividing 283 by 855, we get 0 with a remainder of 283.
The number 0 becomes the next digit in our result. 
Result so far: 9360.0
Subtracting 0 from 283 leaves us with 283.
Take the next digit (5) from the dividend and append it to 283, then repeat: 2835 / 855

Advancing to step 8:
2835 divided by 855 is 3 with a remainder of 270.
The number 3 becomes the next digit in our result. 
Result so far: 93603.0
The remainder is 270 after subtracting 2565 from 2835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 9:
When dividing 2700 by 855, we get 3 with a remainder of 135.
Use 3 as the next digit of our solution. 
Result so far: 93603.3
Subtract 2565 from 2700 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 10:
If we divide 1350 by 855, we get 1 and a remainder of 495.
The next digit of our result is 1. 
Result so far: 93603.31
If we take 855 away from 1350, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 11:
The number 855 fits into 4950 5 times, leaving a remainder of 675.
Write down 5 as next digit of the result. 
Result so far: 93603.315
The remainder is 675 after subtracting 4275 from 4950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Moving on to step 12:
If we divide 6750 by 855, we get 7 and a remainder of 765.
Put 7 as the next digit of the answer. 
Result so far: 93603.3157
If we take 5985 away from 6750, we end up with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Advancing to step 13:
The number 855 fits into 7650 8 times, leaving a remainder of 810.
Write down 8 as next digit of the result. 
Result so far: 93603.31578
The remainder is 810 after subtracting 6840 from 7650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 14:
8100 divided by 855 is 9 with a remainder of 405.
The number 9 becomes the next digit in our result. 
Result so far: 93603.315789
If we subtract 7695 from 8100, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 15:
When dividing 4050 by 855, we get 4 with a remainder of 630.
Put 4 as the next digit of the answer. 
Result so far: 93603.3157894
Deduct 3420 from 4050 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 16:
If we divide 6300 by 855, we get 7 and a remainder of 315.
The next digit of our result is 7. 
Result so far: 93603.31578947
Subtracting 5985 from 6300 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final outcome is 93603.31578947, with a leftover of 3.15e-07.
