We're dividing 40398829 by 988 
Our goal is to divide 40398829 by 988.

Advancing to step 1:
4 divided by 988 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 988

Moving on to step 2:
When dividing 40 by 988, we get 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 988

Advancing to step 3:
403 divided by 988 is 0 with a remainder of 403.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 403, we get 403.
Grab the next digit (9) from the dividend, add it to 403, then carry on: 4039 / 988

Moving on to step 4:
When dividing 4039 by 988, we get 4 with a remainder of 87.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 3952 from 4039 and we're left with 87.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 988

On to step 5:
988 can be fit into 878 0 times, resulting in a remainder of 878.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 878, we end up with 878.
Fetch the next digit (8) from the dividend, attach it to 878 and continue: 8788 / 988

Step 6:
The number 988 fits into 8788 8 times, leaving a remainder of 884.
Write down 8 as next digit of the result. 
Result so far: 408.0
If we subtract 7904 from 8788, we get 884.
Include the next digit (2) from the dividend after 884, then repeat: 8842 / 988

Let's proceed to step 7:
When dividing 8842 by 988, we get 8 with a remainder of 938.
Record the quotient 8 as the next digit in the result. 
Result so far: 4088.0
If we subtract 7904 from 8842, we get 938.
Fetch the next digit (9) from the dividend, attach it to 938 and continue: 9389 / 988

On to step 8:
If we divide 9389 by 988, we get 9 and a remainder of 497.
Write down 9 as next digit of the result. 
Result so far: 40889.0
The remainder is 497 after subtracting 8892 from 9389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Moving on to step 9:
When dividing 4970 by 988, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 40889.5
Subtract 4940 from 4970 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 988, we get 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 40889.5
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 11:
3000 divided by 988 is 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 40889.503
The remainder is 36 after subtracting 2964 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
360 divided by 988 is 0 with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 40889.503
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.

Going ahead to step 13:
When dividing 3600 by 988, we get 3 with a remainder of 636.
Record the quotient 3 as the next digit in the result. 
Result so far: 40889.50303
The remainder is 636 after subtracting 2964 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 14:
988 can be fit into 6360 6 times, resulting in a remainder of 432.
The number 6 becomes the next digit in our result. 
Result so far: 40889.503036
If we subtract 5928 from 6360, we get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 15:
988 goes into 4320 4 times with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 40889.5030364
Subtract 3952 from 4320 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 16:
The number 988 fits into 3680 3 times, leaving a remainder of 716.
Record the quotient 3 as the next digit in the result. 
Result so far: 40889.50303643
If we take 2964 away from 3680, we end up with 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

The quotient of the division is 40889.50303643, and the remainder is 7.16e-07.
