Let's divide 30630821 by 998
We want to figure out the number of times 30630821 can be divided by 998.

Going ahead to step 1:
The number 998 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 998

Advancing to step 2:
If we divide 30 by 998, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 998

On to step 3:
998 can be fit into 306 0 times, resulting in a remainder of 306.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 306, we get 306.
Grab the next digit (3) from the dividend, add it to 306, then carry on: 3063 / 998

Advancing to step 4:
998 can be fit into 3063 3 times, resulting in a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 2994 from 3063 to get 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 998

On to step 5:
If we divide 690 by 998, we get 0 and a remainder of 690.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 690, we get 690.
Fetch the next digit (8) from the dividend, attach it to 690 and continue: 6908 / 998

Moving on to step 6:
When dividing 6908 by 998, we get 6 with a remainder of 920.
Record the quotient 6 as the next digit in the result. 
Result so far: 306.0
If we take 5988 away from 6908, we end up with 920.
Take the next digit (2) from the dividend and append it to 920, then repeat: 9202 / 998

Advancing to step 7:
If we divide 9202 by 998, we get 9 and a remainder of 220.
Put 9 as the next digit of the answer. 
Result so far: 3069.0
If we take 8982 away from 9202, we end up with 220.
Grab the next digit (1) from the dividend, add it to 220, then carry on: 2201 / 998

On to step 8:
The number 998 fits into 2201 2 times, leaving a remainder of 205.
Record the quotient 2 as the next digit in the result. 
Result so far: 30692.0
The remainder is 205 after subtracting 1996 from 2201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 9:
The number 998 fits into 2050 2 times, leaving a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 30692.2
Deduct 1996 from 2050 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
540 divided by 998 is 0 with a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 30692.2
Subtract 0 from 540 to get 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 11:
The number 998 fits into 5400 5 times, leaving a remainder of 410.
The next digit of our result is 5. 
Result so far: 30692.205
If we take 4990 away from 5400, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 12:
998 goes into 4100 4 times with a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 30692.2054
Subtract 3992 from 4100 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 13:
1080 divided by 998 is 1 with a remainder of 82.
The next digit of our result is 1. 
Result so far: 30692.20541
If we subtract 998 from 1080, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 14:
The number 998 fits into 820 0 times, leaving a remainder of 820.
The number 0 becomes the next digit in our result. 
Result so far: 30692.20541
Subtract 0 from 820 to get 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8200, and continue the process.

Going ahead to step 15:
998 can be fit into 8200 8 times, resulting in a remainder of 216.
The number 8 becomes the next digit in our result. 
Result so far: 30692.2054108
Subtract 7984 from 8200 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 16:
2160 divided by 998 is 2 with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 30692.20541082
If we take 1996 away from 2160, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Our division results in 30692.20541082 with a remaining 1.64e-07.
