81210449 ÷ 993 
We're looking to find how many times 993 goes into 81210449.

Going ahead to step 1:
The number 993 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 993

Going ahead to step 2:
993 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 993

Moving on to step 3:
When dividing 812 by 993, we get 0 with a remainder of 812.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 812 after subtracting 0 from 812.
Include the next digit (1) from the dividend after 812, then repeat: 8121 / 993

Step 4:
The number 993 fits into 8121 8 times, leaving a remainder of 177.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 7944 from 8121, we get 177.
Grab the next digit (0) from the dividend, add it to 177, then carry on: 1770 / 993

On to step 5:
When dividing 1770 by 993, we get 1 with a remainder of 777.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
Deduct 993 from 1770 and we're left with 777.
Include the next digit (4) from the dividend after 777, then repeat: 7774 / 993

On to step 6:
993 can be fit into 7774 7 times, resulting in a remainder of 823.
Put 7 as the next digit of the answer. 
Result so far: 817.0
If we take 6951 away from 7774, we end up with 823.
Grab the next digit (4) from the dividend, add it to 823, then carry on: 8234 / 993

Step 7:
993 goes into 8234 8 times with a remainder of 290.
Use 8 as the next digit of our solution. 
Result so far: 8178.0
If we subtract 7944 from 8234, we get 290.
Grab the next digit (9) from the dividend, add it to 290, then carry on: 2909 / 993

Going ahead to step 8:
993 goes into 2909 2 times with a remainder of 923.
The next digit of our result is 2. 
Result so far: 81782.0
Subtract 1986 from 2909 to get 923.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9230, and continue the process.

Moving on to step 9:
9230 divided by 993 is 9 with a remainder of 293.
Use 9 as the next digit of our solution. 
Result so far: 81782.9
If we take 8937 away from 9230, we end up with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Step 10:
993 goes into 2930 2 times with a remainder of 944.
Put 2 as the next digit of the answer. 
Result so far: 81782.92
Subtract 1986 from 2930 to get 944.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

Let's proceed to step 11:
When dividing 9440 by 993, we get 9 with a remainder of 503.
Record the quotient 9 as the next digit in the result. 
Result so far: 81782.929
Subtracting 8937 from 9440 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Step 12:
993 goes into 5030 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 81782.9295
Deduct 4965 from 5030 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 13:
993 goes into 650 0 times with a remainder of 650.
Record the quotient 0 as the next digit in the result. 
Result so far: 81782.9295
Deduct 0 from 650 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 14:
993 goes into 6500 6 times with a remainder of 542.
Write down 6 as next digit of the result. 
Result so far: 81782.929506
If we subtract 5958 from 6500, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Step 15:
If we divide 5420 by 993, we get 5 and a remainder of 455.
Record the quotient 5 as the next digit in the result. 
Result so far: 81782.9295065
If we subtract 4965 from 5420, we get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Moving on to step 16:
4550 divided by 993 is 4 with a remainder of 578.
Use 4 as the next digit of our solution. 
Result so far: 81782.92950654
The remainder is 578 after subtracting 3972 from 4550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

After the division, we end up with 81782.92950654 and a remainder of 5.78e-07.
