36639355 ÷ 873 
Our goal is to divide 36639355 by 873.

On to step 1:
873 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 873

Going ahead to step 2:
If we divide 36 by 873, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 873

On to step 3:
The number 873 fits into 366 0 times, leaving a remainder of 366.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 366 leaves us with 366.
Bring next digit (3) of the dividend behind the 366 and repeat the process: 3663 / 873

Going ahead to step 4:
873 can be fit into 3663 4 times, resulting in a remainder of 171.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3492 from 3663 and we're left with 171.
Bring next digit (9) of the dividend behind the 171 and repeat the process: 1719 / 873

Advancing to step 5:
When dividing 1719 by 873, we get 1 with a remainder of 846.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 846 after subtracting 873 from 1719.
Take the next digit (3) from the dividend and append it to 846, then repeat: 8463 / 873

Going ahead to step 6:
If we divide 8463 by 873, we get 9 and a remainder of 606.
The number 9 becomes the next digit in our result. 
Result so far: 419.0
The remainder is 606 after subtracting 7857 from 8463.
Bring next digit (5) of the dividend behind the 606 and repeat the process: 6065 / 873

Step 7:
6065 divided by 873 is 6 with a remainder of 827.
Put 6 as the next digit of the answer. 
Result so far: 4196.0
The remainder is 827 after subtracting 5238 from 6065.
Take the next digit (5) from the dividend and append it to 827, then repeat: 8275 / 873

Step 8:
If we divide 8275 by 873, we get 9 and a remainder of 418.
The number 9 becomes the next digit in our result. 
Result so far: 41969.0
If we subtract 7857 from 8275, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 9:
The number 873 fits into 4180 4 times, leaving a remainder of 688.
Use 4 as the next digit of our solution. 
Result so far: 41969.4
Subtract 3492 from 4180 to get 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 10:
If we divide 6880 by 873, we get 7 and a remainder of 769.
Record the quotient 7 as the next digit in the result. 
Result so far: 41969.47
The remainder is 769 after subtracting 6111 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7690, and continue the process.

Moving on to step 11:
873 goes into 7690 8 times with a remainder of 706.
Put 8 as the next digit of the answer. 
Result so far: 41969.478
The remainder is 706 after subtracting 6984 from 7690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Let's proceed to step 12:
The number 873 fits into 7060 8 times, leaving a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 41969.4788
If we subtract 6984 from 7060, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 41969.4788, with a leftover of 0.00076.
