We're dividing 66905193 by 993 
We want to figure out the number of times 66905193 can be divided by 993.

Going ahead to step 1:
If we divide 6 by 993, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 993

Step 2:
The number 993 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 993

Let's proceed to step 3:
993 can be fit into 669 0 times, resulting in a remainder of 669.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 669 leaves us with 669.
Grab the next digit (0) from the dividend, add it to 669, then carry on: 6690 / 993

On to step 4:
If we divide 6690 by 993, we get 6 and a remainder of 732.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 5958 from 6690 leaves us with 732.
Include the next digit (5) from the dividend after 732, then repeat: 7325 / 993

On to step 5:
993 can be fit into 7325 7 times, resulting in a remainder of 374.
Record the quotient 7 as the next digit in the result. 
Result so far: 67.0
The remainder is 374 after subtracting 6951 from 7325.
Grab the next digit (1) from the dividend, add it to 374, then carry on: 3741 / 993

Going ahead to step 6:
3741 divided by 993 is 3 with a remainder of 762.
Write down 3 as next digit of the result. 
Result so far: 673.0
If we take 2979 away from 3741, we end up with 762.
Take the next digit (9) from the dividend and append it to 762, then repeat: 7629 / 993

Moving on to step 7:
If we divide 7629 by 993, we get 7 and a remainder of 678.
The number 7 becomes the next digit in our result. 
Result so far: 6737.0
If we take 6951 away from 7629, we end up with 678.
Take the next digit (3) from the dividend and append it to 678, then repeat: 6783 / 993

Advancing to step 8:
6783 divided by 993 is 6 with a remainder of 825.
Write down 6 as next digit of the result. 
Result so far: 67376.0
Deduct 5958 from 6783 and we're left with 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Moving on to step 9:
8250 divided by 993 is 8 with a remainder of 306.
The number 8 becomes the next digit in our result. 
Result so far: 67376.8
Deduct 7944 from 8250 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 10:
If we divide 3060 by 993, we get 3 and a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 67376.83
Subtract 2979 from 3060 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 11:
When dividing 810 by 993, we get 0 with a remainder of 810.
Write down 0 as next digit of the result. 
Result so far: 67376.83
If we subtract 0 from 810, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Going ahead to step 12:
The number 993 fits into 8100 8 times, leaving a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 67376.8308
Deduct 7944 from 8100 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 13:
If we divide 1560 by 993, we get 1 and a remainder of 567.
The next digit of our result is 1. 
Result so far: 67376.83081
Subtract 993 from 1560 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

On to step 14:
The number 993 fits into 5670 5 times, leaving a remainder of 705.
The next digit of our result is 5. 
Result so far: 67376.830815
Deduct 4965 from 5670 and we're left with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Advancing to step 15:
993 goes into 7050 7 times with a remainder of 99.
Write down 7 as next digit of the result. 
Result so far: 67376.8308157
If we take 6951 away from 7050, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 16:
990 divided by 993 is 0 with a remainder of 990.
The number 0 becomes the next digit in our result. 
Result so far: 67376.8308157
Subtracting 0 from 990 leaves us with 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9900, and continue the process.

The final result is 67376.8308157 with a remainder of 9.9e-07.
