We divide 86949840 by 263
The aim is to understand the frequency of 263 in 86949840.

Step 1:
263 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 263

Step 2:
263 goes into 86 0 times with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Fetch the next digit (9) from the dividend, attach it to 86 and continue: 869 / 263

Advancing to step 3:
If we divide 869 by 263, we get 3 and a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 789 from 869 and we're left with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 263

Step 4:
263 goes into 804 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
The remainder is 15 after subtracting 789 from 804.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 263

Let's proceed to step 5:
If we divide 159 by 263, we get 0 and a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 330.0
Subtract 0 from 159 to get 159.
Bring next digit (8) of the dividend behind the 159 and repeat the process: 1598 / 263

On to step 6:
The number 263 fits into 1598 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 3306.0
The remainder is 20 after subtracting 1578 from 1598.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 263

Going ahead to step 7:
The number 263 fits into 204 0 times, leaving a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 33060.0
If we subtract 0 from 204, we get 204.
Take the next digit (0) from the dividend and append it to 204, then repeat: 2040 / 263

On to step 8:
When dividing 2040 by 263, we get 7 with a remainder of 199.
Record the quotient 7 as the next digit in the result. 
Result so far: 330607.0
The remainder is 199 after subtracting 1841 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 9:
1990 divided by 263 is 7 with a remainder of 149.
The number 7 becomes the next digit in our result. 
Result so far: 330607.7
Deduct 1841 from 1990 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 10:
When dividing 1490 by 263, we get 5 with a remainder of 175.
The next digit of our result is 5. 
Result so far: 330607.75
Deduct 1315 from 1490 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 11:
1750 divided by 263 is 6 with a remainder of 172.
The next digit of our result is 6. 
Result so far: 330607.756
Deduct 1578 from 1750 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 12:
263 goes into 1720 6 times with a remainder of 142.
The number 6 becomes the next digit in our result. 
Result so far: 330607.7566
Subtract 1578 from 1720 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

The final result is 330607.7566 with a remainder of 0.00142.
