We divide 28836129 by 551
The aim is to understand the frequency of 551 in 28836129.

Advancing to step 1:
The number 551 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 551

Advancing to step 2:
If we divide 28 by 551, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 551

Let's proceed to step 3:
If we divide 288 by 551, we get 0 and a remainder of 288.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 288 to get 288.
Bring next digit (3) of the dividend behind the 288 and repeat the process: 2883 / 551

Going ahead to step 4:
551 can be fit into 2883 5 times, resulting in a remainder of 128.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 128 after subtracting 2755 from 2883.
Bring next digit (6) of the dividend behind the 128 and repeat the process: 1286 / 551

Let's proceed to step 5:
551 can be fit into 1286 2 times, resulting in a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 1102 from 1286 leaves us with 184.
Bring next digit (1) of the dividend behind the 184 and repeat the process: 1841 / 551

Moving on to step 6:
If we divide 1841 by 551, we get 3 and a remainder of 188.
The next digit of our result is 3. 
Result so far: 523.0
Subtracting 1653 from 1841 leaves us with 188.
Bring next digit (2) of the dividend behind the 188 and repeat the process: 1882 / 551

Step 7:
The number 551 fits into 1882 3 times, leaving a remainder of 229.
The next digit of our result is 3. 
Result so far: 5233.0
The remainder is 229 after subtracting 1653 from 1882.
Bring next digit (9) of the dividend behind the 229 and repeat the process: 2299 / 551

Going ahead to step 8:
When dividing 2299 by 551, we get 4 with a remainder of 95.
Write down 4 as next digit of the result. 
Result so far: 52334.0
Deduct 2204 from 2299 and we're left with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Step 9:
When dividing 950 by 551, we get 1 with a remainder of 399.
Put 1 as the next digit of the answer. 
Result so far: 52334.1
If we take 551 away from 950, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Let's proceed to step 10:
The number 551 fits into 3990 7 times, leaving a remainder of 133.
The number 7 becomes the next digit in our result. 
Result so far: 52334.17
The remainder is 133 after subtracting 3857 from 3990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Let's proceed to step 11:
When dividing 1330 by 551, we get 2 with a remainder of 228.
The next digit of our result is 2. 
Result so far: 52334.172
Subtracting 1102 from 1330 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 12:
If we divide 2280 by 551, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 52334.1724
If we take 2204 away from 2280, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
551 can be fit into 760 1 times, resulting in a remainder of 209.
The next digit of our result is 1. 
Result so far: 52334.17241
If we take 551 away from 760, we end up with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 14:
551 goes into 2090 3 times with a remainder of 437.
Use 3 as the next digit of our solution. 
Result so far: 52334.172413
Subtract 1653 from 2090 to get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Let's proceed to step 15:
When dividing 4370 by 551, we get 7 with a remainder of 513.
Use 7 as the next digit of our solution. 
Result so far: 52334.1724137
The remainder is 513 after subtracting 3857 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Going ahead to step 16:
551 can be fit into 5130 9 times, resulting in a remainder of 171.
The number 9 becomes the next digit in our result. 
Result so far: 52334.17241379
If we subtract 4959 from 5130, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

The final outcome is 52334.17241379, with a leftover of 1.71e-07.
