We divide 42042631 by 403
The aim is to understand the frequency of 403 in 42042631.

Moving on to step 1:
If we divide 4 by 403, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 403

On to step 2:
403 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 403

Moving on to step 3:
The number 403 fits into 420 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 403 away from 420, we end up with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 403

Moving on to step 4:
When dividing 174 by 403, we get 0 with a remainder of 174.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 174, we get 174.
Append the next digit (2) from the dividend to 174 and continue with: 1742 / 403

Step 5:
1742 divided by 403 is 4 with a remainder of 130.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 1612 from 1742 and we're left with 130.
Take the next digit (6) from the dividend and append it to 130, then repeat: 1306 / 403

Let's proceed to step 6:
The number 403 fits into 1306 3 times, leaving a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 1043.0
Deduct 1209 from 1306 and we're left with 97.
Fetch the next digit (3) from the dividend, attach it to 97 and continue: 973 / 403

Moving on to step 7:
When dividing 973 by 403, we get 2 with a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 10432.0
Subtracting 806 from 973 leaves us with 167.
Bring next digit (1) of the dividend behind the 167 and repeat the process: 1671 / 403

Advancing to step 8:
1671 divided by 403 is 4 with a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 104324.0
If we subtract 1612 from 1671, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 9:
If we divide 590 by 403, we get 1 and a remainder of 187.
Use 1 as the next digit of our solution. 
Result so far: 104324.1
If we take 403 away from 590, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Advancing to step 10:
When dividing 1870 by 403, we get 4 with a remainder of 258.
The next digit of our result is 4. 
Result so far: 104324.14
If we take 1612 away from 1870, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 11:
2580 divided by 403 is 6 with a remainder of 162.
Write down 6 as next digit of the result. 
Result so far: 104324.146
Subtract 2418 from 2580 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 12:
1620 divided by 403 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 104324.1464
The remainder is 8 after subtracting 1612 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 403 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 104324.1464
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 14:
403 can be fit into 800 1 times, resulting in a remainder of 397.
The next digit of our result is 1. 
Result so far: 104324.146401
The remainder is 397 after subtracting 403 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 15:
403 goes into 3970 9 times with a remainder of 343.
Write down 9 as next digit of the result. 
Result so far: 104324.1464019
Subtract 3627 from 3970 to get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Advancing to step 16:
403 can be fit into 3430 8 times, resulting in a remainder of 206.
Use 8 as the next digit of our solution. 
Result so far: 104324.14640198
The remainder is 206 after subtracting 3224 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

The final result is 104324.14640198 with a remainder of 2.06e-07.
