We look at the division of 23349925 by 673 
The aim is to understand the frequency of 673 in 23349925.

Let's proceed to step 1:
2 divided by 673 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 673

Moving on to step 2:
673 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 673

On to step 3:
673 goes into 233 0 times with a remainder of 233.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 233 to get 233.
Grab the next digit (4) from the dividend, add it to 233, then carry on: 2334 / 673

Step 4:
The number 673 fits into 2334 3 times, leaving a remainder of 315.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2019 from 2334 to get 315.
Include the next digit (9) from the dividend after 315, then repeat: 3159 / 673

Let's proceed to step 5:
673 can be fit into 3159 4 times, resulting in a remainder of 467.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 2692 away from 3159, we end up with 467.
Take the next digit (9) from the dividend and append it to 467, then repeat: 4679 / 673

On to step 6:
If we divide 4679 by 673, we get 6 and a remainder of 641.
Put 6 as the next digit of the answer. 
Result so far: 346.0
The remainder is 641 after subtracting 4038 from 4679.
Include the next digit (2) from the dividend after 641, then repeat: 6412 / 673

Going ahead to step 7:
When dividing 6412 by 673, we get 9 with a remainder of 355.
The number 9 becomes the next digit in our result. 
Result so far: 3469.0
If we take 6057 away from 6412, we end up with 355.
Include the next digit (5) from the dividend after 355, then repeat: 3555 / 673

Going ahead to step 8:
If we divide 3555 by 673, we get 5 and a remainder of 190.
Put 5 as the next digit of the answer. 
Result so far: 34695.0
Subtract 3365 from 3555 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 9:
1900 divided by 673 is 2 with a remainder of 554.
Put 2 as the next digit of the answer. 
Result so far: 34695.2
Subtract 1346 from 1900 to get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 10:
The number 673 fits into 5540 8 times, leaving a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 34695.28
The remainder is 156 after subtracting 5384 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 11:
When dividing 1560 by 673, we get 2 with a remainder of 214.
Record the quotient 2 as the next digit in the result. 
Result so far: 34695.282
Subtracting 1346 from 1560 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 12:
When dividing 2140 by 673, we get 3 with a remainder of 121.
The number 3 becomes the next digit in our result. 
Result so far: 34695.2823
The remainder is 121 after subtracting 2019 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 13:
673 goes into 1210 1 times with a remainder of 537.
Use 1 as the next digit of our solution. 
Result so far: 34695.28231
The remainder is 537 after subtracting 673 from 1210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5370, and continue the process.

On to step 14:
673 goes into 5370 7 times with a remainder of 659.
Use 7 as the next digit of our solution. 
Result so far: 34695.282317
Subtracting 4711 from 5370 leaves us with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Going ahead to step 15:
If we divide 6590 by 673, we get 9 and a remainder of 533.
Use 9 as the next digit of our solution. 
Result so far: 34695.2823179
The remainder is 533 after subtracting 6057 from 6590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Moving on to step 16:
5330 divided by 673 is 7 with a remainder of 619.
The next digit of our result is 7. 
Result so far: 34695.28231797
If we subtract 4711 from 5330, we get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

The final outcome is 34695.28231797, with a leftover of 6.19e-07.
