71997768 divided by 855 
We want to divide 71997768 by 855.

Step 1:
7 divided by 855 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 855

Let's proceed to step 2:
When dividing 71 by 855, we get 0 with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 855

Step 3:
When dividing 719 by 855, we get 0 with a remainder of 719.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 719 leaves us with 719.
Append the next digit (9) from the dividend to 719 and continue with: 7199 / 855

Step 4:
When dividing 7199 by 855, we get 8 with a remainder of 359.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 359 after subtracting 6840 from 7199.
Include the next digit (7) from the dividend after 359, then repeat: 3597 / 855

Moving on to step 5:
The number 855 fits into 3597 4 times, leaving a remainder of 177.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtract 3420 from 3597 to get 177.
Bring next digit (7) of the dividend behind the 177 and repeat the process: 1777 / 855

Moving on to step 6:
When dividing 1777 by 855, we get 2 with a remainder of 67.
The number 2 becomes the next digit in our result. 
Result so far: 842.0
The remainder is 67 after subtracting 1710 from 1777.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 855

Step 7:
If we divide 676 by 855, we get 0 and a remainder of 676.
The number 0 becomes the next digit in our result. 
Result so far: 8420.0
Subtracting 0 from 676 leaves us with 676.
Take the next digit (8) from the dividend and append it to 676, then repeat: 6768 / 855

Going ahead to step 8:
When dividing 6768 by 855, we get 7 with a remainder of 783.
Write down 7 as next digit of the result. 
Result so far: 84207.0
Subtracting 5985 from 6768 leaves us with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Moving on to step 9:
When dividing 7830 by 855, we get 9 with a remainder of 135.
Record the quotient 9 as the next digit in the result. 
Result so far: 84207.9
If we subtract 7695 from 7830, we 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.

Let's proceed to step 10:
855 can be fit into 1350 1 times, resulting in a remainder of 495.
Record the quotient 1 as the next digit in the result. 
Result so far: 84207.91
Subtracting 855 from 1350 leaves us 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.

Step 11:
If we divide 4950 by 855, we get 5 and a remainder of 675.
Use 5 as the next digit of our solution. 
Result so far: 84207.915
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:
When dividing 6750 by 855, we get 7 with a remainder of 765.
The next digit of our result is 7. 
Result so far: 84207.9157
Deduct 5985 from 6750 and we're left 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.

Moving on to step 13:
855 can be fit into 7650 8 times, resulting in a remainder of 810.
Write down 8 as next digit of the result. 
Result so far: 84207.91578
If we subtract 6840 from 7650, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Going ahead to step 14:
If we divide 8100 by 855, we get 9 and a remainder of 405.
Put 9 as the next digit of the answer. 
Result so far: 84207.915789
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.

Step 15:
855 goes into 4050 4 times with a remainder of 630.
Record the quotient 4 as the next digit in the result. 
Result so far: 84207.9157894
Subtract 3420 from 4050 to get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 16:
855 goes into 6300 7 times with a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 84207.91578947
The remainder is 315 after subtracting 5985 from 6300.
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 84207.91578947, with a leftover of 3.15e-07.
