We're dividing 81304080 by 611 
The aim is to understand the frequency of 611 in 81304080.

Step 1:
8 divided by 611 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 611

On to step 2:
81 divided by 611 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 611

Advancing to step 3:
611 can be fit into 813 1 times, resulting in a remainder of 202.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 611 from 813 to get 202.
Grab the next digit (0) from the dividend, add it to 202, then carry on: 2020 / 611

Advancing to step 4:
611 goes into 2020 3 times with a remainder of 187.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 1833 from 2020 leaves us with 187.
Include the next digit (4) from the dividend after 187, then repeat: 1874 / 611

Let's proceed to step 5:
611 goes into 1874 3 times with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
The remainder is 41 after subtracting 1833 from 1874.
Grab the next digit (0) from the dividend, add it to 41, then carry on: 410 / 611

Let's proceed to step 6:
410 divided by 611 is 0 with a remainder of 410.
Use 0 as the next digit of our solution. 
Result so far: 1330.0
The remainder is 410 after subtracting 0 from 410.
Grab the next digit (8) from the dividend, add it to 410, then carry on: 4108 / 611

Advancing to step 7:
611 goes into 4108 6 times with a remainder of 442.
Record the quotient 6 as the next digit in the result. 
Result so far: 13306.0
Deduct 3666 from 4108 and we're left with 442.
Take the next digit (0) from the dividend and append it to 442, then repeat: 4420 / 611

Advancing to step 8:
4420 divided by 611 is 7 with a remainder of 143.
Write down 7 as next digit of the result. 
Result so far: 133067.0
Deduct 4277 from 4420 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Moving on to step 9:
611 goes into 1430 2 times with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 133067.2
If we take 1222 away from 1430, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 10:
If we divide 2080 by 611, we get 3 and a remainder of 247.
Record the quotient 3 as the next digit in the result. 
Result so far: 133067.23
The remainder is 247 after subtracting 1833 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 11:
When dividing 2470 by 611, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 133067.234
Subtracting 2444 from 2470 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
When dividing 260 by 611, we get 0 with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 133067.234
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 13:
2600 divided by 611 is 4 with a remainder of 156.
Record the quotient 4 as the next digit in the result. 
Result so far: 133067.23404
Subtracting 2444 from 2600 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 14:
The number 611 fits into 1560 2 times, leaving a remainder of 338.
Use 2 as the next digit of our solution. 
Result so far: 133067.234042
Subtract 1222 from 1560 to get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 15:
611 can be fit into 3380 5 times, resulting in a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 133067.2340425
Subtract 3055 from 3380 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 16:
3250 divided by 611 is 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 133067.23404255
Deduct 3055 from 3250 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

After the division, we end up with 133067.23404255 and a remainder of 1.95e-07.
