We look at the division of 83006098 by 631 
The aim is to understand the frequency of 631 in 83006098.

Advancing to step 1:
8 divided by 631 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 631

Moving on to step 2:
631 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (0) of the dividend behind the 83 and repeat the process: 830 / 631

Going ahead to step 3:
If we divide 830 by 631, we get 1 and a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 631 away from 830, we end up with 199.
Append the next digit (0) from the dividend to 199 and continue with: 1990 / 631

Moving on to step 4:
631 goes into 1990 3 times with a remainder of 97.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1893 from 1990 leaves us with 97.
Include the next digit (6) from the dividend after 97, then repeat: 976 / 631

On to step 5:
631 goes into 976 1 times with a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
If we take 631 away from 976, we end up with 345.
Include the next digit (0) from the dividend after 345, then repeat: 3450 / 631

Let's proceed to step 6:
If we divide 3450 by 631, we get 5 and a remainder of 295.
The next digit of our result is 5. 
Result so far: 1315.0
If we take 3155 away from 3450, we end up with 295.
Take the next digit (9) from the dividend and append it to 295, then repeat: 2959 / 631

On to step 7:
When dividing 2959 by 631, we get 4 with a remainder of 435.
The number 4 becomes the next digit in our result. 
Result so far: 13154.0
Subtracting 2524 from 2959 leaves us with 435.
Append the next digit (8) from the dividend to 435 and continue with: 4358 / 631

Going ahead to step 8:
631 goes into 4358 6 times with a remainder of 572.
Put 6 as the next digit of the answer. 
Result so far: 131546.0
If we take 3786 away from 4358, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 9:
5720 divided by 631 is 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 131546.9
Subtract 5679 from 5720 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
When dividing 410 by 631, we get 0 with a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 131546.9
Subtract 0 from 410 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 11:
The number 631 fits into 4100 6 times, leaving a remainder of 314.
The number 6 becomes the next digit in our result. 
Result so far: 131546.906
The remainder is 314 after subtracting 3786 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 12:
3140 divided by 631 is 4 with a remainder of 616.
Write down 4 as next digit of the result. 
Result so far: 131546.9064
Deduct 2524 from 3140 and we're left with 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 13:
631 can be fit into 6160 9 times, resulting in a remainder of 481.
Use 9 as the next digit of our solution. 
Result so far: 131546.90649
If we subtract 5679 from 6160, we get 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Advancing to step 14:
The number 631 fits into 4810 7 times, leaving a remainder of 393.
Write down 7 as next digit of the result. 
Result so far: 131546.906497
If we subtract 4417 from 4810, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

On to step 15:
631 can be fit into 3930 6 times, resulting in a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 131546.9064976
Subtract 3786 from 3930 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 16:
If we divide 1440 by 631, we get 2 and a remainder of 178.
Use 2 as the next digit of our solution. 
Result so far: 131546.90649762
The remainder is 178 after subtracting 1262 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

After the division, we end up with 131546.90649762 and a remainder of 1.78e-07.
