We look at the division of 56961509 by 631 
The aim is to understand the frequency of 631 in 56961509.

Advancing to step 1:
The number 631 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 631

Let's proceed to step 2:
If we divide 56 by 631, we get 0 and a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Append the next digit (9) from the dividend to 56 and continue with: 569 / 631

Let's proceed to step 3:
If we divide 569 by 631, we get 0 and a remainder of 569.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 569 after subtracting 0 from 569.
Fetch the next digit (6) from the dividend, attach it to 569 and continue: 5696 / 631

Let's proceed to step 4:
5696 divided by 631 is 9 with a remainder of 17.
The next digit of our result is 9. 
Result so far: 9.0
If we take 5679 away from 5696, we end up with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 631

Let's proceed to step 5:
If we divide 171 by 631, we get 0 and a remainder of 171.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
Subtract 0 from 171 to get 171.
Fetch the next digit (5) from the dividend, attach it to 171 and continue: 1715 / 631

Let's proceed to step 6:
The number 631 fits into 1715 2 times, leaving a remainder of 453.
Record the quotient 2 as the next digit in the result. 
Result so far: 902.0
Subtracting 1262 from 1715 leaves us with 453.
Grab the next digit (0) from the dividend, add it to 453, then carry on: 4530 / 631

Going ahead to step 7:
If we divide 4530 by 631, we get 7 and a remainder of 113.
The next digit of our result is 7. 
Result so far: 9027.0
The remainder is 113 after subtracting 4417 from 4530.
Include the next digit (9) from the dividend after 113, then repeat: 1139 / 631

Step 8:
If we divide 1139 by 631, we get 1 and a remainder of 508.
Use 1 as the next digit of our solution. 
Result so far: 90271.0
The remainder is 508 after subtracting 631 from 1139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Step 9:
The number 631 fits into 5080 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 90271.8
Subtract 5048 from 5080 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
When dividing 320 by 631, we get 0 with a remainder of 320.
The next digit of our result is 0. 
Result so far: 90271.8
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 11:
If we divide 3200 by 631, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 90271.805
Subtract 3155 from 3200 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
The number 631 fits into 450 0 times, leaving a remainder of 450.
The next digit of our result is 0. 
Result so far: 90271.805
The remainder is 450 after subtracting 0 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 13:
When dividing 4500 by 631, we get 7 with a remainder of 83.
The next digit of our result is 7. 
Result so far: 90271.80507
Subtracting 4417 from 4500 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 14:
The number 631 fits into 830 1 times, leaving a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 90271.805071
If we take 631 away from 830, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Moving on to step 15:
631 goes into 1990 3 times with a remainder of 97.
Write down 3 as next digit of the result. 
Result so far: 90271.8050713
If we subtract 1893 from 1990, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 16:
The number 631 fits into 970 1 times, leaving a remainder of 339.
Write down 1 as next digit of the result. 
Result so far: 90271.80507131
Subtracting 631 from 970 leaves us with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

The quotient of the division is 90271.80507131, and the remainder is 3.39e-07.
