We divide 31966831 by 403
The aim is to understand the frequency of 403 in 31966831.

Step 1:
The number 403 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 403

Advancing to step 2:
403 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 403

Advancing to step 3:
403 can be fit into 319 0 times, resulting in a remainder of 319.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 319 leaves us with 319.
Append the next digit (6) from the dividend to 319 and continue with: 3196 / 403

Step 4:
403 goes into 3196 7 times with a remainder of 375.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 375 after subtracting 2821 from 3196.
Fetch the next digit (6) from the dividend, attach it to 375 and continue: 3756 / 403

Let's proceed to step 5:
When dividing 3756 by 403, we get 9 with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtract 3627 from 3756 to get 129.
Include the next digit (8) from the dividend after 129, then repeat: 1298 / 403

On to step 6:
1298 divided by 403 is 3 with a remainder of 89.
Record the quotient 3 as the next digit in the result. 
Result so far: 793.0
Deduct 1209 from 1298 and we're left with 89.
Grab the next digit (3) from the dividend, add it to 89, then carry on: 893 / 403

Moving on to step 7:
403 can be fit into 893 2 times, resulting in a remainder of 87.
Record the quotient 2 as the next digit in the result. 
Result so far: 7932.0
Subtract 806 from 893 to get 87.
Include the next digit (1) from the dividend after 87, then repeat: 871 / 403

Moving on to step 8:
The number 403 fits into 871 2 times, leaving a remainder of 65.
The number 2 becomes the next digit in our result. 
Result so far: 79322.0
If we take 806 away from 871, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
If we divide 650 by 403, we get 1 and a remainder of 247.
Put 1 as the next digit of the answer. 
Result so far: 79322.1
Subtract 403 from 650 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Step 10:
403 goes into 2470 6 times with a remainder of 52.
The next digit of our result is 6. 
Result so far: 79322.16
If we subtract 2418 from 2470, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 403, we get 1 with a remainder of 117.
Put 1 as the next digit of the answer. 
Result so far: 79322.161
If we take 403 away from 520, we end up with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Step 12:
403 can be fit into 1170 2 times, resulting in a remainder of 364.
Write down 2 as next digit of the result. 
Result so far: 79322.1612
The remainder is 364 after subtracting 806 from 1170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 13:
3640 divided by 403 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 79322.16129
Subtract 3627 from 3640 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
The number 403 fits into 130 0 times, leaving a remainder of 130.
Put 0 as the next digit of the answer. 
Result so far: 79322.16129
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 15:
If we divide 1300 by 403, we get 3 and a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 79322.1612903
Subtracting 1209 from 1300 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 16:
403 goes into 910 2 times with a remainder of 104.
The next digit of our result is 2. 
Result so far: 79322.16129032
The remainder is 104 after subtracting 806 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 79322.16129032 and a remainder of 1.04e-07.
