Let's divide 19399221 by 993
We want to figure out the number of times 19399221 can be divided by 993.

On to step 1:
When dividing 1 by 993, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 993

Going ahead to step 2:
If we divide 19 by 993, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 993

Let's proceed to step 3:
If we divide 193 by 993, we get 0 and a remainder of 193.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 193 leaves us with 193.
Append the next digit (9) from the dividend to 193 and continue with: 1939 / 993

On to step 4:
The number 993 fits into 1939 1 times, leaving a remainder of 946.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 993 from 1939 leaves us with 946.
Take the next digit (9) from the dividend and append it to 946, then repeat: 9469 / 993

Advancing to step 5:
993 can be fit into 9469 9 times, resulting in a remainder of 532.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 8937 from 9469, we get 532.
Bring next digit (2) of the dividend behind the 532 and repeat the process: 5322 / 993

On to step 6:
The number 993 fits into 5322 5 times, leaving a remainder of 357.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Deduct 4965 from 5322 and we're left with 357.
Grab the next digit (2) from the dividend, add it to 357, then carry on: 3572 / 993

Moving on to step 7:
The number 993 fits into 3572 3 times, leaving a remainder of 593.
Put 3 as the next digit of the answer. 
Result so far: 1953.0
Subtract 2979 from 3572 to get 593.
Append the next digit (1) from the dividend to 593 and continue with: 5931 / 993

Let's proceed to step 8:
993 can be fit into 5931 5 times, resulting in a remainder of 966.
The number 5 becomes the next digit in our result. 
Result so far: 19535.0
Subtract 4965 from 5931 to get 966.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9660, and continue the process.

On to step 9:
When dividing 9660 by 993, we get 9 with a remainder of 723.
Use 9 as the next digit of our solution. 
Result so far: 19535.9
The remainder is 723 after subtracting 8937 from 9660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7230, and continue the process.

Let's proceed to step 10:
The number 993 fits into 7230 7 times, leaving a remainder of 279.
Use 7 as the next digit of our solution. 
Result so far: 19535.97
Subtracting 6951 from 7230 leaves us with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 11:
993 goes into 2790 2 times with a remainder of 804.
Record the quotient 2 as the next digit in the result. 
Result so far: 19535.972
Subtracting 1986 from 2790 leaves us with 804.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Step 12:
If we divide 8040 by 993, we get 8 and a remainder of 96.
The next digit of our result is 8. 
Result so far: 19535.9728
If we take 7944 away from 8040, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 13:
960 divided by 993 is 0 with a remainder of 960.
The next digit of our result is 0. 
Result so far: 19535.9728
Subtracting 0 from 960 leaves us with 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9600, and continue the process.

Advancing to step 14:
When dividing 9600 by 993, we get 9 with a remainder of 663.
Put 9 as the next digit of the answer. 
Result so far: 19535.972809
Subtract 8937 from 9600 to get 663.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

On to step 15:
The number 993 fits into 6630 6 times, leaving a remainder of 672.
The next digit of our result is 6. 
Result so far: 19535.9728096
Deduct 5958 from 6630 and we're left with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

On to step 16:
When dividing 6720 by 993, we get 6 with a remainder of 762.
Put 6 as the next digit of the answer. 
Result so far: 19535.97280966
If we take 5958 away from 6720, we end up with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

The final result is 19535.97280966 with a remainder of 7.62e-07.
