63203745 ÷ 431 
The aim is to understand the frequency of 431 in 63203745.

On to step 1:
431 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 431

Step 2:
431 can be fit into 63 0 times, resulting in a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (2) from the dividend and append it to 63, then repeat: 632 / 431

Let's proceed to step 3:
The number 431 fits into 632 1 times, leaving a remainder of 201.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 431 from 632 to get 201.
Take the next digit (0) from the dividend and append it to 201, then repeat: 2010 / 431

On to step 4:
431 can be fit into 2010 4 times, resulting in a remainder of 286.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 286 after subtracting 1724 from 2010.
Include the next digit (3) from the dividend after 286, then repeat: 2863 / 431

Advancing to step 5:
The number 431 fits into 2863 6 times, leaving a remainder of 277.
Write down 6 as next digit of the result. 
Result so far: 146.0
If we take 2586 away from 2863, we end up with 277.
Fetch the next digit (7) from the dividend, attach it to 277 and continue: 2777 / 431

Step 6:
When dividing 2777 by 431, we get 6 with a remainder of 191.
Use 6 as the next digit of our solution. 
Result so far: 1466.0
If we subtract 2586 from 2777, we get 191.
Take the next digit (4) from the dividend and append it to 191, then repeat: 1914 / 431

Advancing to step 7:
1914 divided by 431 is 4 with a remainder of 190.
The next digit of our result is 4. 
Result so far: 14664.0
If we subtract 1724 from 1914, we get 190.
Fetch the next digit (5) from the dividend, attach it to 190 and continue: 1905 / 431

Step 8:
When dividing 1905 by 431, we get 4 with a remainder of 181.
The next digit of our result is 4. 
Result so far: 146644.0
The remainder is 181 after subtracting 1724 from 1905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 9:
When dividing 1810 by 431, we get 4 with a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 146644.4
If we subtract 1724 from 1810, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 10:
When dividing 860 by 431, we get 1 with a remainder of 429.
Write down 1 as next digit of the result. 
Result so far: 146644.41
Subtracting 431 from 860 leaves us with 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Moving on to step 11:
4290 divided by 431 is 9 with a remainder of 411.
The next digit of our result is 9. 
Result so far: 146644.419
Subtracting 3879 from 4290 leaves us with 411.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Advancing to step 12:
431 can be fit into 4110 9 times, resulting in a remainder of 231.
Write down 9 as next digit of the result. 
Result so far: 146644.4199
Subtract 3879 from 4110 to get 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

After the division, we end up with 146644.4199 and a remainder of 0.00231.
