99580153 divided by 999 
We want to figure out the number of times 99580153 can be divided by 999.

Moving on to step 1:
The number 999 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 999

Going ahead to step 2:
999 can be fit into 99 0 times, resulting in a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Include the next digit (5) from the dividend after 99, then repeat: 995 / 999

Let's proceed to step 3:
The number 999 fits into 995 0 times, leaving a remainder of 995.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 995, we get 995.
Fetch the next digit (8) from the dividend, attach it to 995 and continue: 9958 / 999

Going ahead to step 4:
999 can be fit into 9958 9 times, resulting in a remainder of 967.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 8991 from 9958, we get 967.
Append the next digit (0) from the dividend to 967 and continue with: 9670 / 999

Let's proceed to step 5:
If we divide 9670 by 999, we get 9 and a remainder of 679.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 8991 from 9670 to get 679.
Append the next digit (1) from the dividend to 679 and continue with: 6791 / 999

Moving on to step 6:
999 can be fit into 6791 6 times, resulting in a remainder of 797.
The next digit of our result is 6. 
Result so far: 996.0
If we subtract 5994 from 6791, we get 797.
Fetch the next digit (5) from the dividend, attach it to 797 and continue: 7975 / 999

Going ahead to step 7:
999 can be fit into 7975 7 times, resulting in a remainder of 982.
Put 7 as the next digit of the answer. 
Result so far: 9967.0
If we take 6993 away from 7975, we end up with 982.
Grab the next digit (3) from the dividend, add it to 982, then carry on: 9823 / 999

Moving on to step 8:
9823 divided by 999 is 9 with a remainder of 832.
The number 9 becomes the next digit in our result. 
Result so far: 99679.0
Deduct 8991 from 9823 and we're left with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Advancing to step 9:
If we divide 8320 by 999, we get 8 and a remainder of 328.
Record the quotient 8 as the next digit in the result. 
Result so far: 99679.8
Subtracting 7992 from 8320 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
The number 999 fits into 3280 3 times, leaving a remainder of 283.
The number 3 becomes the next digit in our result. 
Result so far: 99679.83
Deduct 2997 from 3280 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 11:
999 goes into 2830 2 times with a remainder of 832.
Put 2 as the next digit of the answer. 
Result so far: 99679.832
If we take 1998 away from 2830, we end up with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Let's proceed to step 12:
999 goes into 8320 8 times with a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 99679.8328
Deduct 7992 from 8320 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 13:
The number 999 fits into 3280 3 times, leaving a remainder of 283.
Write down 3 as next digit of the result. 
Result so far: 99679.83283
Deduct 2997 from 3280 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 14:
999 goes into 2830 2 times with a remainder of 832.
Put 2 as the next digit of the answer. 
Result so far: 99679.832832
The remainder is 832 after subtracting 1998 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Going ahead to step 15:
999 goes into 8320 8 times with a remainder of 328.
Write down 8 as next digit of the result. 
Result so far: 99679.8328328
If we subtract 7992 from 8320, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 16:
The number 999 fits into 3280 3 times, leaving a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 99679.83283283
If we subtract 2997 from 3280, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

The final result is 99679.83283283 with a remainder of 2.83e-07.
