81103301 divided by 73 
The aim is to understand the frequency of 73 in 81103301.

On to step 1:
73 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 73

Advancing to step 2:
When dividing 81 by 73, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 73 from 81 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 73

Advancing to step 3:
73 goes into 81 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 73 from 81 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 73

Advancing to step 4:
The number 73 fits into 80 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 111.0
Deduct 73 from 80 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 73

Let's proceed to step 5:
If we divide 73 by 73, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1111.0
If we take 73 away from 73, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 73

Going ahead to step 6:
If we divide 3 by 73, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 11110.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 73

Moving on to step 7:
30 divided by 73 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 111100.0
If we take 0 away from 30, we end up with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 73

On to step 8:
73 can be fit into 301 4 times, resulting in a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 1111004.0
If we subtract 292 from 301, 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.

Let's proceed to step 9:
If we divide 90 by 73, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1111004.1
If we take 73 away from 90, we end up 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 10:
If we divide 170 by 73, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1111004.12
The remainder is 24 after subtracting 146 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
240 divided by 73 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 1111004.123
Subtracting 219 from 240 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 12:
If we divide 210 by 73, we get 2 and a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 1111004.1232
The remainder is 64 after subtracting 146 from 210.
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 13:
The number 73 fits into 640 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 1111004.12328
Deduct 584 from 640 and we're left 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.

Going ahead to step 14:
When dividing 560 by 73, we get 7 with a remainder of 49.
The next digit of our result is 7. 
Result so far: 1111004.123287
Deduct 511 from 560 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 15:
73 can be fit into 490 6 times, resulting in a remainder of 52.
The next digit of our result is 6. 
Result so far: 1111004.1232876
Deduct 438 from 490 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 16:
If we divide 520 by 73, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 1111004.12328767
Subtract 511 from 520 to 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.

The quotient of the division is 1111004.12328767, and the remainder is 9e-09.
