83427745 divided by 673 
The aim is to understand the frequency of 673 in 83427745.

On to step 1:
673 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 673

On to step 2:
673 goes into 83 0 times with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Append the next digit (4) from the dividend to 83 and continue with: 834 / 673

Advancing to step 3:
673 goes into 834 1 times with a remainder of 161.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 673 away from 834, we end up with 161.
Append the next digit (2) from the dividend to 161 and continue with: 1612 / 673

Let's proceed to step 4:
673 can be fit into 1612 2 times, resulting in a remainder of 266.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 1346 from 1612 to get 266.
Include the next digit (7) from the dividend after 266, then repeat: 2667 / 673

On to step 5:
2667 divided by 673 is 3 with a remainder of 648.
The next digit of our result is 3. 
Result so far: 123.0
If we subtract 2019 from 2667, we get 648.
Append the next digit (7) from the dividend to 648 and continue with: 6487 / 673

Step 6:
673 goes into 6487 9 times with a remainder of 430.
The number 9 becomes the next digit in our result. 
Result so far: 1239.0
If we subtract 6057 from 6487, we get 430.
Fetch the next digit (4) from the dividend, attach it to 430 and continue: 4304 / 673

Let's proceed to step 7:
The number 673 fits into 4304 6 times, leaving a remainder of 266.
Record the quotient 6 as the next digit in the result. 
Result so far: 12396.0
If we take 4038 away from 4304, we end up with 266.
Include the next digit (5) from the dividend after 266, then repeat: 2665 / 673

Moving on to step 8:
If we divide 2665 by 673, we get 3 and a remainder of 646.
Put 3 as the next digit of the answer. 
Result so far: 123963.0
Deduct 2019 from 2665 and we're left with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 9:
The number 673 fits into 6460 9 times, leaving a remainder of 403.
Write down 9 as next digit of the result. 
Result so far: 123963.9
The remainder is 403 after subtracting 6057 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Let's proceed to step 10:
673 goes into 4030 5 times with a remainder of 665.
Put 5 as the next digit of the answer. 
Result so far: 123963.95
If we take 3365 away from 4030, we end up with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Advancing to step 11:
673 goes into 6650 9 times with a remainder of 593.
Record the quotient 9 as the next digit in the result. 
Result so far: 123963.959
The remainder is 593 after subtracting 6057 from 6650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5930, and continue the process.

Step 12:
The number 673 fits into 5930 8 times, leaving a remainder of 546.
Use 8 as the next digit of our solution. 
Result so far: 123963.9598
The remainder is 546 after subtracting 5384 from 5930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 13:
5460 divided by 673 is 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 123963.95988
If we subtract 5384 from 5460, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 123963.95988 with a remaining 7.6e-05.
