We're dividing 83664903 by 631 
The aim is to understand the frequency of 631 in 83664903.

Step 1:
The number 631 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 631

Let's proceed to step 2:
If we divide 83 by 631, we get 0 and a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 83 after subtracting 0 from 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 631

Moving on to step 3:
631 goes into 836 1 times with a remainder of 205.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 631 away from 836, we end up with 205.
Append the next digit (6) from the dividend to 205 and continue with: 2056 / 631

Step 4:
631 goes into 2056 3 times with a remainder of 163.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1893 from 2056 leaves us with 163.
Bring next digit (4) of the dividend behind the 163 and repeat the process: 1634 / 631

On to step 5:
The number 631 fits into 1634 2 times, leaving a remainder of 372.
Record the quotient 2 as the next digit in the result. 
Result so far: 132.0
If we take 1262 away from 1634, we end up with 372.
Bring next digit (9) of the dividend behind the 372 and repeat the process: 3729 / 631

Going ahead to step 6:
The number 631 fits into 3729 5 times, leaving a remainder of 574.
The number 5 becomes the next digit in our result. 
Result so far: 1325.0
Deduct 3155 from 3729 and we're left with 574.
Include the next digit (0) from the dividend after 574, then repeat: 5740 / 631

Moving on to step 7:
If we divide 5740 by 631, we get 9 and a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 13259.0
Subtracting 5679 from 5740 leaves us with 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 631

Let's proceed to step 8:
613 divided by 631 is 0 with a remainder of 613.
Write down 0 as next digit of the result. 
Result so far: 132590.0
The remainder is 613 after subtracting 0 from 613.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6130, and continue the process.

Going ahead to step 9:
6130 divided by 631 is 9 with a remainder of 451.
The number 9 becomes the next digit in our result. 
Result so far: 132590.9
The remainder is 451 after subtracting 5679 from 6130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 10:
4510 divided by 631 is 7 with a remainder of 93.
Write down 7 as next digit of the result. 
Result so far: 132590.97
If we take 4417 away from 4510, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 11:
631 goes into 930 1 times with a remainder of 299.
The next digit of our result is 1. 
Result so far: 132590.971
Subtract 631 from 930 to get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Going ahead to step 12:
The number 631 fits into 2990 4 times, leaving a remainder of 466.
The next digit of our result is 4. 
Result so far: 132590.9714
Subtracting 2524 from 2990 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Advancing to step 13:
When dividing 4660 by 631, we get 7 with a remainder of 243.
The number 7 becomes the next digit in our result. 
Result so far: 132590.97147
Subtract 4417 from 4660 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 14:
631 can be fit into 2430 3 times, resulting in a remainder of 537.
Use 3 as the next digit of our solution. 
Result so far: 132590.971473
Subtract 1893 from 2430 to get 537.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

Moving on to step 15:
The number 631 fits into 5370 8 times, leaving a remainder of 322.
The number 8 becomes the next digit in our result. 
Result so far: 132590.9714738
Subtract 5048 from 5370 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 16:
The number 631 fits into 3220 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 132590.97147385
Deduct 3155 from 3220 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 132590.97147385, with a leftover of 6.5e-08.
