37421501 divided by 631 
The aim is to understand the frequency of 631 in 37421501.

Step 1:
3 divided by 631 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 631

Let's proceed to step 2:
37 divided by 631 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 37 to get 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 631

Moving on to step 3:
The number 631 fits into 374 0 times, leaving a remainder of 374.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 374 leaves us with 374.
Bring next digit (2) of the dividend behind the 374 and repeat the process: 3742 / 631

Going ahead to step 4:
If we divide 3742 by 631, we get 5 and a remainder of 587.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 3155 from 3742 to get 587.
Take the next digit (1) from the dividend and append it to 587, then repeat: 5871 / 631

Advancing to step 5:
The number 631 fits into 5871 9 times, leaving a remainder of 192.
The next digit of our result is 9. 
Result so far: 59.0
If we take 5679 away from 5871, we end up with 192.
Grab the next digit (5) from the dividend, add it to 192, then carry on: 1925 / 631

Step 6:
The number 631 fits into 1925 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 593.0
The remainder is 32 after subtracting 1893 from 1925.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 631

Moving on to step 7:
The number 631 fits into 320 0 times, leaving a remainder of 320.
The next digit of our result is 0. 
Result so far: 5930.0
Subtract 0 from 320 to get 320.
Take the next digit (1) from the dividend and append it to 320, then repeat: 3201 / 631

Advancing to step 8:
631 can be fit into 3201 5 times, resulting in a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 59305.0
The remainder is 46 after subtracting 3155 from 3201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
If we divide 460 by 631, we get 0 and a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 59305.0
The remainder is 460 after subtracting 0 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Moving on to step 10:
The number 631 fits into 4600 7 times, leaving a remainder of 183.
The number 7 becomes the next digit in our result. 
Result so far: 59305.07
If we take 4417 away from 4600, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Advancing to step 11:
1830 divided by 631 is 2 with a remainder of 568.
Write down 2 as next digit of the result. 
Result so far: 59305.072
Subtract 1262 from 1830 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Step 12:
The number 631 fits into 5680 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 59305.0729
The remainder is 1 after subtracting 5679 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
When dividing 10 by 631, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 59305.0729
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
631 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 59305.0729
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 59305.0729, with a leftover of 1e-05.
