We're dividing 51436822 by 263 
The aim is to understand the frequency of 263 in 51436822.

Let's proceed to step 1:
If we divide 5 by 263, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 263

On to step 2:
263 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (4) from the dividend and append it to 51, then repeat: 514 / 263

Let's proceed to step 3:
When dividing 514 by 263, we get 1 with a remainder of 251.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 263 from 514 to get 251.
Append the next digit (3) from the dividend to 251 and continue with: 2513 / 263

Advancing to step 4:
When dividing 2513 by 263, we get 9 with a remainder of 146.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtracting 2367 from 2513 leaves us with 146.
Grab the next digit (6) from the dividend, add it to 146, then carry on: 1466 / 263

Step 5:
263 can be fit into 1466 5 times, resulting in a remainder of 151.
Write down 5 as next digit of the result. 
Result so far: 195.0
Deduct 1315 from 1466 and we're left with 151.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 263

On to step 6:
263 can be fit into 1518 5 times, resulting in a remainder of 203.
Use 5 as the next digit of our solution. 
Result so far: 1955.0
Subtract 1315 from 1518 to get 203.
Bring next digit (2) of the dividend behind the 203 and repeat the process: 2032 / 263

On to step 7:
When dividing 2032 by 263, we get 7 with a remainder of 191.
The number 7 becomes the next digit in our result. 
Result so far: 19557.0
Subtracting 1841 from 2032 leaves us with 191.
Grab the next digit (2) from the dividend, add it to 191, then carry on: 1912 / 263

Let's proceed to step 8:
263 can be fit into 1912 7 times, resulting in a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 195577.0
If we take 1841 away from 1912, we end up 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.

Let's proceed to step 9:
263 can be fit into 710 2 times, resulting in a remainder of 184.
The next digit of our result is 2. 
Result so far: 195577.2
If we subtract 526 from 710, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 10:
If we divide 1840 by 263, we get 6 and a remainder of 262.
Record the quotient 6 as the next digit in the result. 
Result so far: 195577.26
If we subtract 1578 from 1840, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 11:
263 can be fit into 2620 9 times, resulting in a remainder of 253.
Put 9 as the next digit of the answer. 
Result so far: 195577.269
If we take 2367 away from 2620, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

On to step 12:
If we divide 2530 by 263, we get 9 and a remainder of 163.
Record the quotient 9 as the next digit in the result. 
Result so far: 195577.2699
Subtract 2367 from 2530 to get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

After the division, we end up with 195577.2699 and a remainder of 0.00163.
