We look at the division of 52383848 by 631 
The aim is to understand the frequency of 631 in 52383848.

On to step 1:
The number 631 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 631

Advancing to step 2:
When dividing 52 by 631, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Take the next digit (3) from the dividend and append it to 52, then repeat: 523 / 631

Step 3:
When dividing 523 by 631, we get 0 with a remainder of 523.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 523 to get 523.
Grab the next digit (8) from the dividend, add it to 523, then carry on: 5238 / 631

Let's proceed to step 4:
If we divide 5238 by 631, we get 8 and a remainder of 190.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 5048 away from 5238, we end up with 190.
Append the next digit (3) from the dividend to 190 and continue with: 1903 / 631

Let's proceed to step 5:
631 can be fit into 1903 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 83.0
If we take 1893 away from 1903, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 631

Step 6:
The number 631 fits into 108 0 times, leaving a remainder of 108.
Put 0 as the next digit of the answer. 
Result so far: 830.0
The remainder is 108 after subtracting 0 from 108.
Take the next digit (4) from the dividend and append it to 108, then repeat: 1084 / 631

Let's proceed to step 7:
The number 631 fits into 1084 1 times, leaving a remainder of 453.
Use 1 as the next digit of our solution. 
Result so far: 8301.0
Subtracting 631 from 1084 leaves us with 453.
Append the next digit (8) from the dividend to 453 and continue with: 4538 / 631

On to step 8:
631 goes into 4538 7 times with a remainder of 121.
Use 7 as the next digit of our solution. 
Result so far: 83017.0
Deduct 4417 from 4538 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 9:
631 can be fit into 1210 1 times, resulting in a remainder of 579.
The next digit of our result is 1. 
Result so far: 83017.1
Subtracting 631 from 1210 leaves us with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Going ahead to step 10:
The number 631 fits into 5790 9 times, leaving a remainder of 111.
Put 9 as the next digit of the answer. 
Result so far: 83017.19
If we subtract 5679 from 5790, we get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 11:
If we divide 1110 by 631, we get 1 and a remainder of 479.
Use 1 as the next digit of our solution. 
Result so far: 83017.191
Subtract 631 from 1110 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 12:
631 goes into 4790 7 times with a remainder of 373.
Use 7 as the next digit of our solution. 
Result so far: 83017.1917
If we subtract 4417 from 4790, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 13:
631 goes into 3730 5 times with a remainder of 575.
Write down 5 as next digit of the result. 
Result so far: 83017.19175
The remainder is 575 after subtracting 3155 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 14:
The number 631 fits into 5750 9 times, leaving a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 83017.191759
Deduct 5679 from 5750 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 15:
631 goes into 710 1 times with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 83017.1917591
Deduct 631 from 710 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 16:
631 can be fit into 790 1 times, resulting in a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 83017.19175911
The remainder is 159 after subtracting 631 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

The final result is 83017.19175911 with a remainder of 1.59e-07.
