Let's divide 31303724 by 403
We want to figure out the number of times 31303724 can be divided by 403.

Going ahead to step 1:
403 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 403

On to step 2:
If we divide 31 by 403, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 403

Step 3:
313 divided by 403 is 0 with a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 313 and we're left with 313.
Take the next digit (0) from the dividend and append it to 313, then repeat: 3130 / 403

Let's proceed to step 4:
The number 403 fits into 3130 7 times, leaving a remainder of 309.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 2821 from 3130 and we're left with 309.
Grab the next digit (3) from the dividend, add it to 309, then carry on: 3093 / 403

Going ahead to step 5:
When dividing 3093 by 403, we get 7 with a remainder of 272.
The next digit of our result is 7. 
Result so far: 77.0
If we take 2821 away from 3093, we end up with 272.
Bring next digit (7) of the dividend behind the 272 and repeat the process: 2727 / 403

Going ahead to step 6:
403 goes into 2727 6 times with a remainder of 309.
Use 6 as the next digit of our solution. 
Result so far: 776.0
If we take 2418 away from 2727, we end up with 309.
Bring next digit (2) of the dividend behind the 309 and repeat the process: 3092 / 403

Going ahead to step 7:
403 goes into 3092 7 times with a remainder of 271.
Put 7 as the next digit of the answer. 
Result so far: 7767.0
Subtract 2821 from 3092 to get 271.
Include the next digit (4) from the dividend after 271, then repeat: 2714 / 403

Step 8:
The number 403 fits into 2714 6 times, leaving a remainder of 296.
The next digit of our result is 6. 
Result so far: 77676.0
Subtracting 2418 from 2714 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 9:
403 goes into 2960 7 times with a remainder of 139.
Put 7 as the next digit of the answer. 
Result so far: 77676.7
If we subtract 2821 from 2960, we get 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 10:
403 can be fit into 1390 3 times, resulting in a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 77676.73
Subtracting 1209 from 1390 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 11:
403 can be fit into 1810 4 times, resulting in a remainder of 198.
The next digit of our result is 4. 
Result so far: 77676.734
If we take 1612 away from 1810, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 12:
1980 divided by 403 is 4 with a remainder of 368.
Write down 4 as next digit of the result. 
Result so far: 77676.7344
The remainder is 368 after subtracting 1612 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

In conclusion, the division gives 77676.7344 with a balance of 0.00368.
