We look at the division of 30471673 by 623 
The aim is to understand the frequency of 623 in 30471673.

On to step 1:
When dividing 3 by 623, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 623

Let's proceed to step 2:
The number 623 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 623

Let's proceed to step 3:
When dividing 304 by 623, we get 0 with a remainder of 304.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 304 and we're left with 304.
Include the next digit (7) from the dividend after 304, then repeat: 3047 / 623

Going ahead to step 4:
623 goes into 3047 4 times with a remainder of 555.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2492 from 3047 to get 555.
Grab the next digit (1) from the dividend, add it to 555, then carry on: 5551 / 623

Let's proceed to step 5:
When dividing 5551 by 623, we get 8 with a remainder of 567.
The next digit of our result is 8. 
Result so far: 48.0
Subtracting 4984 from 5551 leaves us with 567.
Append the next digit (6) from the dividend to 567 and continue with: 5676 / 623

Step 6:
When dividing 5676 by 623, we get 9 with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 489.0
If we take 5607 away from 5676, we end up with 69.
Append the next digit (7) from the dividend to 69 and continue with: 697 / 623

Going ahead to step 7:
623 goes into 697 1 times with a remainder of 74.
The next digit of our result is 1. 
Result so far: 4891.0
Subtracting 623 from 697 leaves us with 74.
Include the next digit (3) from the dividend after 74, then repeat: 743 / 623

Moving on to step 8:
When dividing 743 by 623, we get 1 with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 48911.0
Subtracting 623 from 743 leaves us 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.

Going ahead to step 9:
623 goes into 1200 1 times with a remainder of 577.
Write down 1 as next digit of the result. 
Result so far: 48911.1
If we subtract 623 from 1200, we get 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

Going ahead to step 10:
When dividing 5770 by 623, we get 9 with a remainder of 163.
Record the quotient 9 as the next digit in the result. 
Result so far: 48911.19
The remainder is 163 after subtracting 5607 from 5770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Moving on to step 11:
623 goes into 1630 2 times with a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 48911.192
If we take 1246 away from 1630, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 12:
623 can be fit into 3840 6 times, resulting in a remainder of 102.
The number 6 becomes the next digit in our result. 
Result so far: 48911.1926
Deduct 3738 from 3840 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 13:
1020 divided by 623 is 1 with a remainder of 397.
Put 1 as the next digit of the answer. 
Result so far: 48911.19261
If we take 623 away from 1020, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

On to step 14:
623 can be fit into 3970 6 times, resulting in a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 48911.192616
Subtract 3738 from 3970 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 15:
If we divide 2320 by 623, we get 3 and a remainder of 451.
Put 3 as the next digit of the answer. 
Result so far: 48911.1926163
Subtract 1869 from 2320 to get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 16:
623 can be fit into 4510 7 times, resulting in a remainder of 149.
The number 7 becomes the next digit in our result. 
Result so far: 48911.19261637
The remainder is 149 after subtracting 4361 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Our division results in 48911.19261637 with a remaining 1.49e-07.
