Let's divide 72163335 by 998
Let's see how many times 998 fits into 72163335.

Going ahead to step 1:
7 divided by 998 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 998

Step 2:
72 divided by 998 is 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 998

Going ahead to step 3:
721 divided by 998 is 0 with a remainder of 721.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 721 and we're left with 721.
Bring next digit (6) of the dividend behind the 721 and repeat the process: 7216 / 998

Step 4:
The number 998 fits into 7216 7 times, leaving a remainder of 230.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 6986 from 7216 to get 230.
Bring next digit (3) of the dividend behind the 230 and repeat the process: 2303 / 998

Moving on to step 5:
998 goes into 2303 2 times with a remainder of 307.
The next digit of our result is 2. 
Result so far: 72.0
Subtract 1996 from 2303 to get 307.
Append the next digit (3) from the dividend to 307 and continue with: 3073 / 998

Moving on to step 6:
If we divide 3073 by 998, we get 3 and a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 723.0
Deduct 2994 from 3073 and we're left with 79.
Take the next digit (3) from the dividend and append it to 79, then repeat: 793 / 998

On to step 7:
The number 998 fits into 793 0 times, leaving a remainder of 793.
The number 0 becomes the next digit in our result. 
Result so far: 7230.0
Deduct 0 from 793 and we're left with 793.
Grab the next digit (5) from the dividend, add it to 793, then carry on: 7935 / 998

Let's proceed to step 8:
When dividing 7935 by 998, we get 7 with a remainder of 949.
The number 7 becomes the next digit in our result. 
Result so far: 72307.0
Subtracting 6986 from 7935 leaves us with 949.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9490, and continue the process.

Advancing to step 9:
998 goes into 9490 9 times with a remainder of 508.
The number 9 becomes the next digit in our result. 
Result so far: 72307.9
Deduct 8982 from 9490 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 10:
5080 divided by 998 is 5 with a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 72307.95
Subtracting 4990 from 5080 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 11:
900 divided by 998 is 0 with a remainder of 900.
Write down 0 as next digit of the result. 
Result so far: 72307.95
Subtract 0 from 900 to get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Let's proceed to step 12:
If we divide 9000 by 998, we get 9 and a remainder of 18.
The next digit of our result is 9. 
Result so far: 72307.9509
If we subtract 8982 from 9000, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
When dividing 180 by 998, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 72307.9509
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 14:
When dividing 1800 by 998, we get 1 with a remainder of 802.
Write down 1 as next digit of the result. 
Result so far: 72307.950901
If we subtract 998 from 1800, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Let's proceed to step 15:
When dividing 8020 by 998, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 72307.9509018
If we subtract 7984 from 8020, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 16:
The number 998 fits into 360 0 times, leaving a remainder of 360.
The number 0 becomes the next digit in our result. 
Result so far: 72307.9509018
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

In conclusion, the division gives 72307.9509018 with a balance of 3.6e-07.
