We look at the division of 94401856 by 631 
The aim is to understand the frequency of 631 in 94401856.

Going ahead to step 1:
When dividing 9 by 631, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 631

Let's proceed to step 2:
The number 631 fits into 94 0 times, leaving a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 94 to get 94.
Append the next digit (4) from the dividend to 94 and continue with: 944 / 631

Going ahead to step 3:
631 can be fit into 944 1 times, resulting in a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 313 after subtracting 631 from 944.
Grab the next digit (0) from the dividend, add it to 313, then carry on: 3130 / 631

Let's proceed to step 4:
The number 631 fits into 3130 4 times, leaving a remainder of 606.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 606 after subtracting 2524 from 3130.
Grab the next digit (1) from the dividend, add it to 606, then carry on: 6061 / 631

Step 5:
If we divide 6061 by 631, we get 9 and a remainder of 382.
Write down 9 as next digit of the result. 
Result so far: 149.0
Subtracting 5679 from 6061 leaves us with 382.
Bring next digit (8) of the dividend behind the 382 and repeat the process: 3828 / 631

Step 6:
631 goes into 3828 6 times with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 1496.0
If we take 3786 away from 3828, we end up with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 631

Moving on to step 7:
425 divided by 631 is 0 with a remainder of 425.
Record the quotient 0 as the next digit in the result. 
Result so far: 14960.0
If we subtract 0 from 425, we get 425.
Take the next digit (6) from the dividend and append it to 425, then repeat: 4256 / 631

Going ahead to step 8:
631 goes into 4256 6 times with a remainder of 470.
Put 6 as the next digit of the answer. 
Result so far: 149606.0
If we subtract 3786 from 4256, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 9:
631 can be fit into 4700 7 times, resulting in a remainder of 283.
Record the quotient 7 as the next digit in the result. 
Result so far: 149606.7
Deduct 4417 from 4700 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 10:
631 goes into 2830 4 times with a remainder of 306.
The next digit of our result is 4. 
Result so far: 149606.74
Subtracting 2524 from 2830 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 11:
631 goes into 3060 4 times with a remainder of 536.
Use 4 as the next digit of our solution. 
Result so far: 149606.744
If we subtract 2524 from 3060, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

After the division, we end up with 149606.744 and a remainder of 0.0536.
