Let's divide 29699962 by 428
The aim is to understand the frequency of 428 in 29699962.

On to step 1:
The number 428 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 428

Step 2:
If we divide 29 by 428, we get 0 and a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Grab the next digit (6) from the dividend, add it to 29, then carry on: 296 / 428

On to step 3:
428 can be fit into 296 0 times, resulting in a remainder of 296.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 296 to get 296.
Append the next digit (9) from the dividend to 296 and continue with: 2969 / 428

On to step 4:
When dividing 2969 by 428, we get 6 with a remainder of 401.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 2568 from 2969 leaves us with 401.
Append the next digit (9) from the dividend to 401 and continue with: 4019 / 428

Step 5:
4019 divided by 428 is 9 with a remainder of 167.
Put 9 as the next digit of the answer. 
Result so far: 69.0
The remainder is 167 after subtracting 3852 from 4019.
Include the next digit (9) from the dividend after 167, then repeat: 1679 / 428

Step 6:
1679 divided by 428 is 3 with a remainder of 395.
The number 3 becomes the next digit in our result. 
Result so far: 693.0
If we subtract 1284 from 1679, we get 395.
Include the next digit (6) from the dividend after 395, then repeat: 3956 / 428

Moving on to step 7:
428 can be fit into 3956 9 times, resulting in a remainder of 104.
Use 9 as the next digit of our solution. 
Result so far: 6939.0
Deduct 3852 from 3956 and we're left with 104.
Fetch the next digit (2) from the dividend, attach it to 104 and continue: 1042 / 428

Going ahead to step 8:
When dividing 1042 by 428, we get 2 with a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 69392.0
Subtracting 856 from 1042 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 9:
428 goes into 1860 4 times with a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 69392.4
Subtracting 1712 from 1860 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
The number 428 fits into 1480 3 times, leaving a remainder of 196.
Put 3 as the next digit of the answer. 
Result so far: 69392.43
Deduct 1284 from 1480 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
When dividing 1960 by 428, we get 4 with a remainder of 248.
Use 4 as the next digit of our solution. 
Result so far: 69392.434
Subtracting 1712 from 1960 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 12:
If we divide 2480 by 428, we get 5 and a remainder of 340.
The next digit of our result is 5. 
Result so far: 69392.4345
If we subtract 2140 from 2480, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 13:
If we divide 3400 by 428, we get 7 and a remainder of 404.
Record the quotient 7 as the next digit in the result. 
Result so far: 69392.43457
If we subtract 2996 from 3400, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 14:
The number 428 fits into 4040 9 times, leaving a remainder of 188.
Put 9 as the next digit of the answer. 
Result so far: 69392.434579
If we subtract 3852 from 4040, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 15:
428 can be fit into 1880 4 times, resulting in a remainder of 168.
The next digit of our result is 4. 
Result so far: 69392.4345794
If we subtract 1712 from 1880, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 16:
428 goes into 1680 3 times with a remainder of 396.
Put 3 as the next digit of the answer. 
Result so far: 69392.43457943
Subtracting 1284 from 1680 leaves us with 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

After the division, we end up with 69392.43457943 and a remainder of 3.96e-07.
