921071 divided by 73 
The aim is to understand the frequency of 73 in 921071.

Moving on to step 1:
9 divided by 73 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 73

On to step 2:
73 can be fit into 92 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 73 from 92 to get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 73

Moving on to step 3:
73 can be fit into 191 2 times, resulting in a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 146 from 191 to get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 73

Advancing to step 4:
The number 73 fits into 450 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 438 away from 450, we end up with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 73

Advancing to step 5:
73 goes into 127 1 times with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1261.0
The remainder is 54 after subtracting 73 from 127.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 73

Moving on to step 6:
The number 73 fits into 541 7 times, leaving a remainder of 30.
The next digit of our result is 7. 
Result so far: 12617.0
The remainder is 30 after subtracting 511 from 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
The number 73 fits into 300 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 12617.4
Deduct 292 from 300 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
The number 73 fits into 80 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 12617.41
If we take 73 away from 80, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
The number 73 fits into 70 0 times, leaving a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 12617.41
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
73 can be fit into 700 9 times, resulting in a remainder of 43.
Put 9 as the next digit of the answer. 
Result so far: 12617.4109
If we subtract 657 from 700, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 11:
73 can be fit into 430 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 12617.41095
If we subtract 365 from 430, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 12:
If we divide 650 by 73, we get 8 and a remainder of 66.
The next digit of our result is 8. 
Result so far: 12617.410958
The remainder is 66 after subtracting 584 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
The number 73 fits into 660 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 12617.4109589
If we subtract 657 from 660, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 14:
73 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 12617.4109589
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 12617.4109589 with a remainder of 3e-08.
