Let's divide 63817504 by 429
The aim is to understand the frequency of 429 in 63817504.

Advancing to step 1:
6 divided by 429 is 0 with a remainder of 6.
The next digit of our result is 0. 
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 / 429

Step 2:
The number 429 fits into 63 0 times, leaving 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.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 429

Let's proceed to step 3:
638 divided by 429 is 1 with a remainder of 209.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 429 from 638, we get 209.
Include the next digit (1) from the dividend after 209, then repeat: 2091 / 429

Advancing to step 4:
The number 429 fits into 2091 4 times, leaving a remainder of 375.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 375 after subtracting 1716 from 2091.
Take the next digit (7) from the dividend and append it to 375, then repeat: 3757 / 429

Moving on to step 5:
3757 divided by 429 is 8 with a remainder of 325.
Use 8 as the next digit of our solution. 
Result so far: 148.0
Deduct 3432 from 3757 and we're left with 325.
Append the next digit (5) from the dividend to 325 and continue with: 3255 / 429

Step 6:
The number 429 fits into 3255 7 times, leaving a remainder of 252.
The next digit of our result is 7. 
Result so far: 1487.0
Subtracting 3003 from 3255 leaves us with 252.
Bring next digit (0) of the dividend behind the 252 and repeat the process: 2520 / 429

Going ahead to step 7:
429 can be fit into 2520 5 times, resulting in a remainder of 375.
The next digit of our result is 5. 
Result so far: 14875.0
If we subtract 2145 from 2520, we get 375.
Include the next digit (4) from the dividend after 375, then repeat: 3754 / 429

Going ahead to step 8:
The number 429 fits into 3754 8 times, leaving a remainder of 322.
The number 8 becomes the next digit in our result. 
Result so far: 148758.0
If we take 3432 away from 3754, we end up with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Step 9:
When dividing 3220 by 429, we get 7 with a remainder of 217.
Put 7 as the next digit of the answer. 
Result so far: 148758.7
The remainder is 217 after subtracting 3003 from 3220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 10:
If we divide 2170 by 429, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 148758.75
Subtract 2145 from 2170 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
429 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 148758.75
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 12:
429 goes into 2500 5 times with a remainder of 355.
Write down 5 as next digit of the result. 
Result so far: 148758.7505
The remainder is 355 after subtracting 2145 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 13:
If we divide 3550 by 429, we get 8 and a remainder of 118.
Use 8 as the next digit of our solution. 
Result so far: 148758.75058
The remainder is 118 after subtracting 3432 from 3550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 14:
429 can be fit into 1180 2 times, resulting in a remainder of 322.
Write down 2 as next digit of the result. 
Result so far: 148758.750582
If we subtract 858 from 1180, we get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 15:
429 can be fit into 3220 7 times, resulting in a remainder of 217.
Use 7 as the next digit of our solution. 
Result so far: 148758.7505827
Deduct 3003 from 3220 and we're left with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Moving on to step 16:
If we divide 2170 by 429, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 148758.75058275
The remainder is 25 after subtracting 2145 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 148758.75058275 and a remainder of 2.5e-08.
