We're dividing 23691395 by 236 
The aim is to understand the frequency of 236 in 23691395.

Step 1:
236 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 236

Going ahead to step 2:
23 divided by 236 is 0 with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 236

Step 3:
236 goes into 236 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 236 from 236, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 236

On to step 4:
When dividing 9 by 236, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 9, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 236

Moving on to step 5:
If we divide 91 by 236, we get 0 and a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtracting 0 from 91 leaves us with 91.
Bring next digit (3) of the dividend behind the 91 and repeat the process: 913 / 236

Advancing to step 6:
If we divide 913 by 236, we get 3 and a remainder of 205.
Put 3 as the next digit of the answer. 
Result so far: 1003.0
Subtract 708 from 913 to get 205.
Bring next digit (9) of the dividend behind the 205 and repeat the process: 2059 / 236

Going ahead to step 7:
If we divide 2059 by 236, we get 8 and a remainder of 171.
Record the quotient 8 as the next digit in the result. 
Result so far: 10038.0
Subtracting 1888 from 2059 leaves us with 171.
Grab the next digit (5) from the dividend, add it to 171, then carry on: 1715 / 236

Going ahead to step 8:
The number 236 fits into 1715 7 times, leaving a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 100387.0
Subtract 1652 from 1715 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 9:
236 can be fit into 630 2 times, resulting in a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 100387.2
If we take 472 away from 630, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
1580 divided by 236 is 6 with a remainder of 164.
Record the quotient 6 as the next digit in the result. 
Result so far: 100387.26
Subtracting 1416 from 1580 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
The number 236 fits into 1640 6 times, leaving a remainder of 224.
Write down 6 as next digit of the result. 
Result so far: 100387.266
The remainder is 224 after subtracting 1416 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 100387.266 with a remainder of 0.0224.
