We're dividing 87756020 by 631 
The aim is to understand the frequency of 631 in 87756020.

Advancing to step 1:
631 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 631

Let's proceed to step 2:
87 divided by 631 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 87 leaves us with 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 631

Let's proceed to step 3:
When dividing 877 by 631, we get 1 with a remainder of 246.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 631 from 877, we get 246.
Include the next digit (5) from the dividend after 246, then repeat: 2465 / 631

Step 4:
2465 divided by 631 is 3 with a remainder of 572.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 1893 from 2465 leaves us with 572.
Bring next digit (6) of the dividend behind the 572 and repeat the process: 5726 / 631

Step 5:
When dividing 5726 by 631, we get 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 139.0
If we take 5679 away from 5726, we end up with 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 631

Let's proceed to step 6:
631 goes into 470 0 times with a remainder of 470.
Record the quotient 0 as the next digit in the result. 
Result so far: 1390.0
Subtracting 0 from 470 leaves us with 470.
Take the next digit (2) from the dividend and append it to 470, then repeat: 4702 / 631

Going ahead to step 7:
If we divide 4702 by 631, we get 7 and a remainder of 285.
The number 7 becomes the next digit in our result. 
Result so far: 13907.0
Subtracting 4417 from 4702 leaves us with 285.
Bring next digit (0) of the dividend behind the 285 and repeat the process: 2850 / 631

Moving on to step 8:
The number 631 fits into 2850 4 times, leaving a remainder of 326.
Use 4 as the next digit of our solution. 
Result so far: 139074.0
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.

Advancing to step 9:
631 goes into 3260 5 times with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 139074.5
If we take 3155 away from 3260, we end up 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.

Going ahead to step 10:
The number 631 fits into 1050 1 times, leaving a remainder of 419.
Put 1 as the next digit of the answer. 
Result so far: 139074.51
If we take 631 away from 1050, we end up 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.

Advancing to step 11:
631 can be fit into 4190 6 times, resulting in a remainder of 404.
Write down 6 as next digit of the result. 
Result so far: 139074.516
Subtract 3786 from 4190 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 12:
If we divide 4040 by 631, we get 6 and a remainder of 254.
Write down 6 as next digit of the result. 
Result so far: 139074.5166
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.

After the division, we end up with 139074.5166 and a remainder of 0.00254.
