We look at the division of 31938852 by 551 
The aim is to understand the frequency of 551 in 31938852.

On to step 1:
If we divide 3 by 551, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 551

Step 2:
551 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (9) from the dividend after 31, then repeat: 319 / 551

Let's proceed to step 3:
551 can be fit into 319 0 times, resulting in a remainder of 319.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 319 and we're left with 319.
Bring next digit (3) of the dividend behind the 319 and repeat the process: 3193 / 551

Going ahead to step 4:
If we divide 3193 by 551, we get 5 and a remainder of 438.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 438 after subtracting 2755 from 3193.
Bring next digit (8) of the dividend behind the 438 and repeat the process: 4388 / 551

Step 5:
The number 551 fits into 4388 7 times, leaving a remainder of 531.
Put 7 as the next digit of the answer. 
Result so far: 57.0
The remainder is 531 after subtracting 3857 from 4388.
Append the next digit (8) from the dividend to 531 and continue with: 5318 / 551

Advancing to step 6:
When dividing 5318 by 551, we get 9 with a remainder of 359.
Write down 9 as next digit of the result. 
Result so far: 579.0
Deduct 4959 from 5318 and we're left with 359.
Take the next digit (5) from the dividend and append it to 359, then repeat: 3595 / 551

On to step 7:
When dividing 3595 by 551, we get 6 with a remainder of 289.
Put 6 as the next digit of the answer. 
Result so far: 5796.0
If we subtract 3306 from 3595, we get 289.
Include the next digit (2) from the dividend after 289, then repeat: 2892 / 551

Going ahead to step 8:
551 goes into 2892 5 times with a remainder of 137.
The number 5 becomes the next digit in our result. 
Result so far: 57965.0
The remainder is 137 after subtracting 2755 from 2892.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 9:
If we divide 1370 by 551, we get 2 and a remainder of 268.
The number 2 becomes the next digit in our result. 
Result so far: 57965.2
Deduct 1102 from 1370 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 10:
2680 divided by 551 is 4 with a remainder of 476.
Write down 4 as next digit of the result. 
Result so far: 57965.24
Subtracting 2204 from 2680 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 11:
551 goes into 4760 8 times with a remainder of 352.
Write down 8 as next digit of the result. 
Result so far: 57965.248
Subtracting 4408 from 4760 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 12:
551 can be fit into 3520 6 times, resulting in a remainder of 214.
Use 6 as the next digit of our solution. 
Result so far: 57965.2486
Deduct 3306 from 3520 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 13:
If we divide 2140 by 551, we get 3 and a remainder of 487.
Write down 3 as next digit of the result. 
Result so far: 57965.24863
Subtracting 1653 from 2140 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Moving on to step 14:
4870 divided by 551 is 8 with a remainder of 462.
Use 8 as the next digit of our solution. 
Result so far: 57965.248638
If we take 4408 away from 4870, we end up with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Moving on to step 15:
551 can be fit into 4620 8 times, resulting in a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 57965.2486388
The remainder is 212 after subtracting 4408 from 4620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The quotient of the division is 57965.2486388, and the remainder is 2.12e-06.
