We look at the division of 47630344 by 668 
The aim is to understand the frequency of 668 in 47630344.

Step 1:
4 divided by 668 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 668

Moving on to step 2:
The number 668 fits into 47 0 times, leaving a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 47, we get 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 668

On to step 3:
668 goes into 476 0 times with a remainder of 476.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 476, we end up with 476.
Bring next digit (3) of the dividend behind the 476 and repeat the process: 4763 / 668

Let's proceed to step 4:
The number 668 fits into 4763 7 times, leaving a remainder of 87.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 4676 from 4763 to get 87.
Grab the next digit (0) from the dividend, add it to 87, then carry on: 870 / 668

Moving on to step 5:
870 divided by 668 is 1 with a remainder of 202.
The next digit of our result is 1. 
Result so far: 71.0
Subtracting 668 from 870 leaves us with 202.
Include the next digit (3) from the dividend after 202, then repeat: 2023 / 668

Step 6:
The number 668 fits into 2023 3 times, leaving a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 713.0
If we subtract 2004 from 2023, we get 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 668

Step 7:
668 goes into 194 0 times with a remainder of 194.
Record the quotient 0 as the next digit in the result. 
Result so far: 7130.0
If we take 0 away from 194, we end up with 194.
Bring next digit (4) of the dividend behind the 194 and repeat the process: 1944 / 668

Advancing to step 8:
The number 668 fits into 1944 2 times, leaving a remainder of 608.
The next digit of our result is 2. 
Result so far: 71302.0
Deduct 1336 from 1944 and we're left with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Going ahead to step 9:
If we divide 6080 by 668, we get 9 and a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 71302.9
The remainder is 68 after subtracting 6012 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 10:
680 divided by 668 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 71302.91
If we take 668 away from 680, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
The number 668 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 71302.91
If we take 0 away from 120, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
If we divide 1200 by 668, we get 1 and a remainder of 532.
Use 1 as the next digit of our solution. 
Result so far: 71302.9101
Subtracting 668 from 1200 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 13:
The number 668 fits into 5320 7 times, leaving a remainder of 644.
Put 7 as the next digit of the answer. 
Result so far: 71302.91017
Subtracting 4676 from 5320 leaves us with 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Let's proceed to step 14:
6440 divided by 668 is 9 with a remainder of 428.
The number 9 becomes the next digit in our result. 
Result so far: 71302.910179
Deduct 6012 from 6440 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 15:
If we divide 4280 by 668, we get 6 and a remainder of 272.
The next digit of our result is 6. 
Result so far: 71302.9101796
The remainder is 272 after subtracting 4008 from 4280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 16:
668 goes into 2720 4 times with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 71302.91017964
If we subtract 2672 from 2720, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 71302.91017964 and a remainder of 4.8e-08.
