We're dividing 29637034 by 428 
The aim is to understand the frequency of 428 in 29637034.

Advancing to step 1:
The number 428 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 428

Step 2:
428 goes into 29 0 times with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 428

Going ahead to step 3:
The number 428 fits into 296 0 times, leaving a remainder of 296.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 296, we end up with 296.
Append the next digit (3) from the dividend to 296 and continue with: 2963 / 428

Advancing to step 4:
428 goes into 2963 6 times with a remainder of 395.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 2568 from 2963 to get 395.
Append the next digit (7) from the dividend to 395 and continue with: 3957 / 428

Step 5:
If we divide 3957 by 428, we get 9 and a remainder of 105.
Put 9 as the next digit of the answer. 
Result so far: 69.0
Subtract 3852 from 3957 to get 105.
Fetch the next digit (0) from the dividend, attach it to 105 and continue: 1050 / 428

Moving on to step 6:
When dividing 1050 by 428, we get 2 with a remainder of 194.
Use 2 as the next digit of our solution. 
Result so far: 692.0
Subtract 856 from 1050 to get 194.
Append the next digit (3) from the dividend to 194 and continue with: 1943 / 428

On to step 7:
If we divide 1943 by 428, we get 4 and a remainder of 231.
Record the quotient 4 as the next digit in the result. 
Result so far: 6924.0
If we subtract 1712 from 1943, we get 231.
Append the next digit (4) from the dividend to 231 and continue with: 2314 / 428

On to step 8:
The number 428 fits into 2314 5 times, leaving a remainder of 174.
Record the quotient 5 as the next digit in the result. 
Result so far: 69245.0
Subtracting 2140 from 2314 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 9:
The number 428 fits into 1740 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 69245.4
Subtracting 1712 from 1740 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
If we divide 280 by 428, we get 0 and a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 69245.4
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 11:
2800 divided by 428 is 6 with a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 69245.406
If we subtract 2568 from 2800, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 12:
428 can be fit into 2320 5 times, resulting in a remainder of 180.
Use 5 as the next digit of our solution. 
Result so far: 69245.4065
Subtracting 2140 from 2320 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 13:
428 goes into 1800 4 times with a remainder of 88.
Write down 4 as next digit of the result. 
Result so far: 69245.40654
Subtracting 1712 from 1800 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 14:
428 goes into 880 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 69245.406542
If we subtract 856 from 880, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 15:
240 divided by 428 is 0 with a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 69245.406542
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 16:
2400 divided by 428 is 5 with a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 69245.40654205
Deduct 2140 from 2400 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The final result is 69245.40654205 with a remainder of 2.6e-07.
