We look at the division of 68400350 by 993 
We want to figure out the number of times 68400350 can be divided by 993.

On to step 1:
993 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 993

Let's proceed to step 2:
993 goes into 68 0 times with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 993

Advancing to step 3:
684 divided by 993 is 0 with a remainder of 684.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 684 to get 684.
Fetch the next digit (0) from the dividend, attach it to 684 and continue: 6840 / 993

Let's proceed to step 4:
When dividing 6840 by 993, we get 6 with a remainder of 882.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 5958 away from 6840, we end up with 882.
Take the next digit (0) from the dividend and append it to 882, then repeat: 8820 / 993

Moving on to step 5:
The number 993 fits into 8820 8 times, leaving a remainder of 876.
The next digit of our result is 8. 
Result so far: 68.0
Subtracting 7944 from 8820 leaves us with 876.
Append the next digit (3) from the dividend to 876 and continue with: 8763 / 993

Going ahead to step 6:
993 can be fit into 8763 8 times, resulting in a remainder of 819.
The next digit of our result is 8. 
Result so far: 688.0
If we take 7944 away from 8763, we end up with 819.
Bring next digit (5) of the dividend behind the 819 and repeat the process: 8195 / 993

On to step 7:
The number 993 fits into 8195 8 times, leaving a remainder of 251.
Write down 8 as next digit of the result. 
Result so far: 6888.0
Subtract 7944 from 8195 to get 251.
Fetch the next digit (0) from the dividend, attach it to 251 and continue: 2510 / 993

On to step 8:
When dividing 2510 by 993, we get 2 with a remainder of 524.
Put 2 as the next digit of the answer. 
Result so far: 68882.0
Deduct 1986 from 2510 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 9:
993 goes into 5240 5 times with a remainder of 275.
Use 5 as the next digit of our solution. 
Result so far: 68882.5
Subtracting 4965 from 5240 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 10:
The number 993 fits into 2750 2 times, leaving a remainder of 764.
Write down 2 as next digit of the result. 
Result so far: 68882.52
Subtracting 1986 from 2750 leaves us with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Going ahead to step 11:
993 goes into 7640 7 times with a remainder of 689.
Record the quotient 7 as the next digit in the result. 
Result so far: 68882.527
If we take 6951 away from 7640, we end up with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

Advancing to step 12:
If we divide 6890 by 993, we get 6 and a remainder of 932.
The number 6 becomes the next digit in our result. 
Result so far: 68882.5276
Subtracting 5958 from 6890 leaves us with 932.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9320, and continue the process.

Going ahead to step 13:
993 goes into 9320 9 times with a remainder of 383.
The next digit of our result is 9. 
Result so far: 68882.52769
Subtract 8937 from 9320 to get 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Advancing to step 14:
993 can be fit into 3830 3 times, resulting in a remainder of 851.
Record the quotient 3 as the next digit in the result. 
Result so far: 68882.527693
If we take 2979 away from 3830, we end up with 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Advancing to step 15:
8510 divided by 993 is 8 with a remainder of 566.
Record the quotient 8 as the next digit in the result. 
Result so far: 68882.5276938
The remainder is 566 after subtracting 7944 from 8510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

On to step 16:
993 goes into 5660 5 times with a remainder of 695.
The number 5 becomes the next digit in our result. 
Result so far: 68882.52769385
Deduct 4965 from 5660 and we're left with 695.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6950, and continue the process.

The final result is 68882.52769385 with a remainder of 6.95e-07.
