We look at the division of 610961 by 73 
The aim is to understand the frequency of 73 in 610961.

On to step 1:
When dividing 6 by 73, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 73

Going ahead to step 2:
The number 73 fits into 61 0 times, leaving a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Grab the next digit (0) from the dividend, add it to 61, then carry on: 610 / 73

Advancing to step 3:
73 can be fit into 610 8 times, resulting in a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 584 from 610 and we're left with 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 73

Let's proceed to step 4:
When dividing 269 by 73, we get 3 with a remainder of 50.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtracting 219 from 269 leaves us with 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 73

On to step 5:
If we divide 506 by 73, we get 6 and a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 836.0
The remainder is 68 after subtracting 438 from 506.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 73

Going ahead to step 6:
If we divide 681 by 73, we get 9 and a remainder of 24.
Put 9 as the next digit of the answer. 
Result so far: 8369.0
Subtract 657 from 681 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
When dividing 240 by 73, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 8369.3
The remainder is 21 after subtracting 219 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
The number 73 fits into 210 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 8369.32
If we subtract 146 from 210, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
The number 73 fits into 640 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 8369.328
If we take 584 away from 640, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
If we divide 560 by 73, we get 7 and a remainder of 49.
Use 7 as the next digit of our solution. 
Result so far: 8369.3287
The remainder is 49 after subtracting 511 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 11:
73 can be fit into 490 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 8369.32876
If we subtract 438 from 490, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
If we divide 520 by 73, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 8369.328767
If we subtract 511 from 520, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
90 divided by 73 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 8369.3287671
Deduct 73 from 90 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
170 divided by 73 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 8369.32876712
Deduct 146 from 170 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 8369.32876712 with a remaining 2.4e-08.
