We look at the division of 52953417 by 631 
The aim is to understand the frequency of 631 in 52953417.

Let's proceed to step 1:
5 divided by 631 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 631

Step 2:
631 goes into 52 0 times with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 631

On to step 3:
If we divide 529 by 631, we get 0 and a remainder of 529.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 529 and we're left with 529.
Include the next digit (5) from the dividend after 529, then repeat: 5295 / 631

On to step 4:
631 goes into 5295 8 times with a remainder of 247.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 5048 from 5295 to get 247.
Append the next digit (3) from the dividend to 247 and continue with: 2473 / 631

Step 5:
When dividing 2473 by 631, we get 3 with a remainder of 580.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we take 1893 away from 2473, we end up with 580.
Append the next digit (4) from the dividend to 580 and continue with: 5804 / 631

Moving on to step 6:
The number 631 fits into 5804 9 times, leaving a remainder of 125.
Put 9 as the next digit of the answer. 
Result so far: 839.0
If we subtract 5679 from 5804, we get 125.
Fetch the next digit (1) from the dividend, attach it to 125 and continue: 1251 / 631

Moving on to step 7:
631 goes into 1251 1 times with a remainder of 620.
Write down 1 as next digit of the result. 
Result so far: 8391.0
Deduct 631 from 1251 and we're left with 620.
Append the next digit (7) from the dividend to 620 and continue with: 6207 / 631

On to step 8:
When dividing 6207 by 631, we get 9 with a remainder of 528.
Write down 9 as next digit of the result. 
Result so far: 83919.0
The remainder is 528 after subtracting 5679 from 6207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 9:
When dividing 5280 by 631, we get 8 with a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 83919.8
Subtract 5048 from 5280 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 10:
If we divide 2320 by 631, we get 3 and a remainder of 427.
Use 3 as the next digit of our solution. 
Result so far: 83919.83
Subtract 1893 from 2320 to get 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Step 11:
631 can be fit into 4270 6 times, resulting in a remainder of 484.
The number 6 becomes the next digit in our result. 
Result so far: 83919.836
If we take 3786 away from 4270, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 12:
The number 631 fits into 4840 7 times, leaving a remainder of 423.
Write down 7 as next digit of the result. 
Result so far: 83919.8367
If we subtract 4417 from 4840, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Moving on to step 13:
If we divide 4230 by 631, we get 6 and a remainder of 444.
Put 6 as the next digit of the answer. 
Result so far: 83919.83676
Subtract 3786 from 4230 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 14:
631 can be fit into 4440 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 83919.836767
The remainder is 23 after subtracting 4417 from 4440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 15:
The number 631 fits into 230 0 times, leaving a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 83919.836767
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Advancing to step 16:
If we divide 2300 by 631, we get 3 and a remainder of 407.
The number 3 becomes the next digit in our result. 
Result so far: 83919.83676703
Deduct 1893 from 2300 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Our division results in 83919.83676703 with a remaining 4.07e-07.
