68172544 divided by 993 
We want to divide 68172544 by 993.

Advancing to step 1:
The number 993 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 993

On to step 2:
68 divided by 993 is 0 with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Include the next digit (1) from the dividend after 68, then repeat: 681 / 993

Advancing to step 3:
When dividing 681 by 993, we get 0 with a remainder of 681.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 681 and we're left with 681.
Bring next digit (7) of the dividend behind the 681 and repeat the process: 6817 / 993

Going ahead to step 4:
993 goes into 6817 6 times with a remainder of 859.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 859 after subtracting 5958 from 6817.
Take the next digit (2) from the dividend and append it to 859, then repeat: 8592 / 993

On to step 5:
993 can be fit into 8592 8 times, resulting in a remainder of 648.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we subtract 7944 from 8592, we get 648.
Append the next digit (5) from the dividend to 648 and continue with: 6485 / 993

Going ahead to step 6:
6485 divided by 993 is 6 with a remainder of 527.
Put 6 as the next digit of the answer. 
Result so far: 686.0
Subtracting 5958 from 6485 leaves us with 527.
Bring next digit (4) of the dividend behind the 527 and repeat the process: 5274 / 993

Going ahead to step 7:
993 goes into 5274 5 times with a remainder of 309.
Use 5 as the next digit of our solution. 
Result so far: 6865.0
Subtracting 4965 from 5274 leaves us with 309.
Take the next digit (4) from the dividend and append it to 309, then repeat: 3094 / 993

Moving on to step 8:
When dividing 3094 by 993, we get 3 with a remainder of 115.
Put 3 as the next digit of the answer. 
Result so far: 68653.0
Deduct 2979 from 3094 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 9:
If we divide 1150 by 993, we get 1 and a remainder of 157.
Record the quotient 1 as the next digit in the result. 
Result so far: 68653.1
Subtract 993 from 1150 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 10:
The number 993 fits into 1570 1 times, leaving a remainder of 577.
The number 1 becomes the next digit in our result. 
Result so far: 68653.11
The remainder is 577 after subtracting 993 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

The quotient of the division is 68653.11, and the remainder is 0.577.
