We look at the division of 38488528 by 551 
The aim is to understand the frequency of 551 in 38488528.

Moving on to step 1:
The number 551 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 551

Advancing to step 2:
551 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 551

Going ahead to step 3:
The number 551 fits into 384 0 times, leaving a remainder of 384.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 384 leaves us with 384.
Take the next digit (8) from the dividend and append it to 384, then repeat: 3848 / 551

Advancing to step 4:
551 can be fit into 3848 6 times, resulting in a remainder of 542.
The next digit of our result is 6. 
Result so far: 6.0
If we take 3306 away from 3848, we end up with 542.
Bring next digit (8) of the dividend behind the 542 and repeat the process: 5428 / 551

Moving on to step 5:
When dividing 5428 by 551, we get 9 with a remainder of 469.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtracting 4959 from 5428 leaves us with 469.
Include the next digit (5) from the dividend after 469, then repeat: 4695 / 551

Step 6:
When dividing 4695 by 551, we get 8 with a remainder of 287.
Put 8 as the next digit of the answer. 
Result so far: 698.0
Subtracting 4408 from 4695 leaves us with 287.
Bring next digit (2) of the dividend behind the 287 and repeat the process: 2872 / 551

Let's proceed to step 7:
551 can be fit into 2872 5 times, resulting in a remainder of 117.
The number 5 becomes the next digit in our result. 
Result so far: 6985.0
Subtract 2755 from 2872 to get 117.
Append the next digit (8) from the dividend to 117 and continue with: 1178 / 551

On to step 8:
If we divide 1178 by 551, we get 2 and a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 69852.0
If we take 1102 away from 1178, 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 9:
When dividing 760 by 551, we get 1 with a remainder of 209.
Use 1 as the next digit of our solution. 
Result so far: 69852.1
Subtracting 551 from 760 leaves us 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.

Advancing to step 10:
551 goes into 2090 3 times with a remainder of 437.
The number 3 becomes the next digit in our result. 
Result so far: 69852.13
The remainder is 437 after subtracting 1653 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Moving on to step 11:
551 goes into 4370 7 times with a remainder of 513.
Record the quotient 7 as the next digit in the result. 
Result so far: 69852.137
Subtract 3857 from 4370 to get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Advancing to step 12:
551 can be fit into 5130 9 times, resulting in a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 69852.1379
If we take 4959 away from 5130, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 13:
551 can be fit into 1710 3 times, resulting in a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 69852.13793
The remainder is 57 after subtracting 1653 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 14:
If we divide 570 by 551, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 69852.137931
The remainder is 19 after subtracting 551 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 15:
551 can be fit into 190 0 times, resulting in a remainder of 190.
Record the quotient 0 as the next digit in the result. 
Result so far: 69852.137931
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 16:
If we divide 1900 by 551, we get 3 and a remainder of 247.
The number 3 becomes the next digit in our result. 
Result so far: 69852.13793103
Deduct 1653 from 1900 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

In conclusion, the division gives 69852.13793103 with a balance of 2.47e-07.
