Let's divide 63166873 by 855
Our goal is to divide 63166873 by 855.

Let's proceed to step 1:
When dividing 6 by 855, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 855

Let's proceed to step 2:
63 divided by 855 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (1) from the dividend to 63 and continue with: 631 / 855

Going ahead to step 3:
The number 855 fits into 631 0 times, leaving a remainder of 631.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 631, we end up with 631.
Take the next digit (6) from the dividend and append it to 631, then repeat: 6316 / 855

On to step 4:
6316 divided by 855 is 7 with a remainder of 331.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 331 after subtracting 5985 from 6316.
Bring next digit (6) of the dividend behind the 331 and repeat the process: 3316 / 855

Moving on to step 5:
855 can be fit into 3316 3 times, resulting in a remainder of 751.
Use 3 as the next digit of our solution. 
Result so far: 73.0
If we subtract 2565 from 3316, we get 751.
Append the next digit (8) from the dividend to 751 and continue with: 7518 / 855

Let's proceed to step 6:
When dividing 7518 by 855, we get 8 with a remainder of 678.
Use 8 as the next digit of our solution. 
Result so far: 738.0
If we take 6840 away from 7518, we end up with 678.
Append the next digit (7) from the dividend to 678 and continue with: 6787 / 855

Advancing to step 7:
The number 855 fits into 6787 7 times, leaving a remainder of 802.
The next digit of our result is 7. 
Result so far: 7387.0
Subtracting 5985 from 6787 leaves us with 802.
Include the next digit (3) from the dividend after 802, then repeat: 8023 / 855

Advancing to step 8:
8023 divided by 855 is 9 with a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 73879.0
If we subtract 7695 from 8023, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 9:
The number 855 fits into 3280 3 times, leaving a remainder of 715.
The number 3 becomes the next digit in our result. 
Result so far: 73879.3
Deduct 2565 from 3280 and we're left with 715.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 10:
The number 855 fits into 7150 8 times, leaving a remainder of 310.
Record the quotient 8 as the next digit in the result. 
Result so far: 73879.38
If we subtract 6840 from 7150, we get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 11:
3100 divided by 855 is 3 with a remainder of 535.
Put 3 as the next digit of the answer. 
Result so far: 73879.383
If we take 2565 away from 3100, we end up with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 12:
855 goes into 5350 6 times with a remainder of 220.
Record the quotient 6 as the next digit in the result. 
Result so far: 73879.3836
Deduct 5130 from 5350 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 13:
2200 divided by 855 is 2 with a remainder of 490.
Use 2 as the next digit of our solution. 
Result so far: 73879.38362
Subtracting 1710 from 2200 leaves us with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Moving on to step 14:
If we divide 4900 by 855, we get 5 and a remainder of 625.
The next digit of our result is 5. 
Result so far: 73879.383625
Subtracting 4275 from 4900 leaves us with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Moving on to step 15:
When dividing 6250 by 855, we get 7 with a remainder of 265.
The number 7 becomes the next digit in our result. 
Result so far: 73879.3836257
If we take 5985 away from 6250, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 16:
2650 divided by 855 is 3 with a remainder of 85.
The number 3 becomes the next digit in our result. 
Result so far: 73879.38362573
If we take 2565 away from 2650, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

The final outcome is 73879.38362573, with a leftover of 8.5e-08.
