80900322 ÷ 263 
The aim is to understand the frequency of 263 in 80900322.

Moving on to step 1:
When dividing 8 by 263, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 263

Going ahead to step 2:
263 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 263

Let's proceed to step 3:
When dividing 809 by 263, we get 3 with a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 20 after subtracting 789 from 809.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 263

Step 4:
263 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 200 and we're left with 200.
Include the next digit (0) from the dividend after 200, then repeat: 2000 / 263

Let's proceed to step 5:
263 goes into 2000 7 times with a remainder of 159.
Record the quotient 7 as the next digit in the result. 
Result so far: 307.0
If we take 1841 away from 2000, we end up with 159.
Bring next digit (3) of the dividend behind the 159 and repeat the process: 1593 / 263

Moving on to step 6:
If we divide 1593 by 263, we get 6 and a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 3076.0
Subtract 1578 from 1593 to get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 263

On to step 7:
If we divide 152 by 263, we get 0 and a remainder of 152.
The number 0 becomes the next digit in our result. 
Result so far: 30760.0
The remainder is 152 after subtracting 0 from 152.
Take the next digit (2) from the dividend and append it to 152, then repeat: 1522 / 263

On to step 8:
263 goes into 1522 5 times with a remainder of 207.
Use 5 as the next digit of our solution. 
Result so far: 307605.0
The remainder is 207 after subtracting 1315 from 1522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 9:
When dividing 2070 by 263, we get 7 with a remainder of 229.
The next digit of our result is 7. 
Result so far: 307605.7
Deduct 1841 from 2070 and we're left with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Advancing to step 10:
263 can be fit into 2290 8 times, resulting in a remainder of 186.
The number 8 becomes the next digit in our result. 
Result so far: 307605.78
Subtract 2104 from 2290 to get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 11:
263 goes into 1860 7 times with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 307605.787
Subtracting 1841 from 1860 leaves us 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.

Moving on to step 12:
263 can be fit into 190 0 times, resulting in a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 307605.787
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 13:
When dividing 1900 by 263, we get 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 307605.78707
Subtracting 1841 from 1900 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 14:
263 goes into 590 2 times with a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 307605.787072
Subtract 526 from 590 to 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.

Step 15:
The number 263 fits into 640 2 times, leaving a remainder of 114.
Put 2 as the next digit of the answer. 
Result so far: 307605.7870722
If we take 526 away from 640, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Our division results in 307605.7870722 with a remaining 1.14e-06.
