We're dividing 70620 by 73 
The aim is to understand the frequency of 73 in 70620.

Advancing to step 1:
When dividing 7 by 73, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 73

Going ahead to step 2:
70 divided by 73 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Take the next digit (6) from the dividend and append it to 70, then repeat: 706 / 73

Going ahead to step 3:
If we divide 706 by 73, we get 9 and a remainder of 49.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 657 from 706 leaves us with 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 73

Let's proceed to step 4:
73 goes into 492 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
Subtract 438 from 492 to get 54.
Bring next digit (0) of the dividend behind the 54 and repeat the process: 540 / 73

Moving on to step 5:
The number 73 fits into 540 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 967.0
If we take 511 away from 540, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 6:
73 can be fit into 290 3 times, resulting in a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 967.3
Subtracting 219 from 290 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 7:
73 can be fit into 710 9 times, resulting in a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 967.39
Deduct 657 from 710 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 8:
If we divide 530 by 73, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 967.397
Deduct 511 from 530 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
73 goes into 190 2 times with a remainder of 44.
The next digit of our result is 2. 
Result so far: 967.3972
If we take 146 away from 190, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
73 goes into 440 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 967.39726
If we take 438 away from 440, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
If we divide 20 by 73, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 967.39726
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
73 goes into 200 2 times with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 967.3972602
If we subtract 146 from 200, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
The number 73 fits into 540 7 times, leaving a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 967.39726027
The remainder is 29 after subtracting 511 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 967.39726027, with a leftover of 2.9e-08.
