We look at the division of 83637442 by 631 
The aim is to understand the frequency of 631 in 83637442.

Advancing to step 1:
If we divide 8 by 631, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 631

Step 2:
If we divide 83 by 631, we get 0 and a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Append the next digit (6) from the dividend to 83 and continue with: 836 / 631

Let's proceed to step 3:
836 divided by 631 is 1 with a remainder of 205.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 205 after subtracting 631 from 836.
Include the next digit (3) from the dividend after 205, then repeat: 2053 / 631

Advancing to step 4:
When dividing 2053 by 631, we get 3 with a remainder of 160.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1893 from 2053 leaves us with 160.
Grab the next digit (7) from the dividend, add it to 160, then carry on: 1607 / 631

Moving on to step 5:
If we divide 1607 by 631, we get 2 and a remainder of 345.
The next digit of our result is 2. 
Result so far: 132.0
If we subtract 1262 from 1607, we get 345.
Include the next digit (4) from the dividend after 345, then repeat: 3454 / 631

Advancing to step 6:
3454 divided by 631 is 5 with a remainder of 299.
Put 5 as the next digit of the answer. 
Result so far: 1325.0
Subtracting 3155 from 3454 leaves us with 299.
Fetch the next digit (4) from the dividend, attach it to 299 and continue: 2994 / 631

Moving on to step 7:
The number 631 fits into 2994 4 times, leaving a remainder of 470.
Record the quotient 4 as the next digit in the result. 
Result so far: 13254.0
Subtract 2524 from 2994 to get 470.
Take the next digit (2) from the dividend and append it to 470, then repeat: 4702 / 631

Going ahead to step 8:
If we divide 4702 by 631, we get 7 and a remainder of 285.
Record the quotient 7 as the next digit in the result. 
Result so far: 132547.0
Deduct 4417 from 4702 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 9:
631 can be fit into 2850 4 times, resulting in a remainder of 326.
Use 4 as the next digit of our solution. 
Result so far: 132547.4
Deduct 2524 from 2850 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 10:
The number 631 fits into 3260 5 times, leaving a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 132547.45
Subtracting 3155 from 3260 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 11:
If we divide 1050 by 631, we get 1 and a remainder of 419.
The number 1 becomes the next digit in our result. 
Result so far: 132547.451
Deduct 631 from 1050 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Moving on to step 12:
631 goes into 4190 6 times with a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 132547.4516
The remainder is 404 after subtracting 3786 from 4190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 13:
631 can be fit into 4040 6 times, resulting in a remainder of 254.
Put 6 as the next digit of the answer. 
Result so far: 132547.45166
If we subtract 3786 from 4040, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

In conclusion, the division gives 132547.45166 with a balance of 0.000254.
