40639295 ÷ 998 
We want to figure out the number of times 40639295 can be divided by 998.

On to step 1:
If we divide 4 by 998, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 998

Moving on to step 2:
998 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (6) from the dividend, add it to 40, then carry on: 406 / 998

Let's proceed to step 3:
If we divide 406 by 998, we get 0 and a remainder of 406.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 406 after subtracting 0 from 406.
Include the next digit (3) from the dividend after 406, then repeat: 4063 / 998

Advancing to step 4:
4063 divided by 998 is 4 with a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 71 after subtracting 3992 from 4063.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 998

Advancing to step 5:
998 can be fit into 719 0 times, resulting in a remainder of 719.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 719, we get 719.
Grab the next digit (2) from the dividend, add it to 719, then carry on: 7192 / 998

Moving on to step 6:
If we divide 7192 by 998, we get 7 and a remainder of 206.
Use 7 as the next digit of our solution. 
Result so far: 407.0
If we take 6986 away from 7192, we end up with 206.
Grab the next digit (9) from the dividend, add it to 206, then carry on: 2069 / 998

Advancing to step 7:
If we divide 2069 by 998, we get 2 and a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 4072.0
The remainder is 73 after subtracting 1996 from 2069.
Append the next digit (5) from the dividend to 73 and continue with: 735 / 998

Step 8:
If we divide 735 by 998, we get 0 and a remainder of 735.
Use 0 as the next digit of our solution. 
Result so far: 40720.0
Subtracting 0 from 735 leaves us with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 9:
998 goes into 7350 7 times with a remainder of 364.
The next digit of our result is 7. 
Result so far: 40720.7
Deduct 6986 from 7350 and we're left with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 10:
The number 998 fits into 3640 3 times, leaving a remainder of 646.
Use 3 as the next digit of our solution. 
Result so far: 40720.73
Subtracting 2994 from 3640 leaves us with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 11:
If we divide 6460 by 998, we get 6 and a remainder of 472.
The number 6 becomes the next digit in our result. 
Result so far: 40720.736
Subtracting 5988 from 6460 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Let's proceed to step 12:
998 goes into 4720 4 times with a remainder of 728.
The next digit of our result is 4. 
Result so far: 40720.7364
The remainder is 728 after subtracting 3992 from 4720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

Going ahead to step 13:
998 can be fit into 7280 7 times, resulting in a remainder of 294.
Put 7 as the next digit of the answer. 
Result so far: 40720.73647
Subtracting 6986 from 7280 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 14:
When dividing 2940 by 998, we get 2 with a remainder of 944.
Write down 2 as next digit of the result. 
Result so far: 40720.736472
Subtracting 1996 from 2940 leaves us with 944.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9440, and continue the process.

Moving on to step 15:
The number 998 fits into 9440 9 times, leaving a remainder of 458.
Record the quotient 9 as the next digit in the result. 
Result so far: 40720.7364729
Subtracting 8982 from 9440 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Going ahead to step 16:
The number 998 fits into 4580 4 times, leaving a remainder of 588.
Use 4 as the next digit of our solution. 
Result so far: 40720.73647294
Deduct 3992 from 4580 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

The quotient of the division is 40720.73647294, and the remainder is 5.88e-07.
