7154920 ÷ 236 
The aim is to understand the frequency of 236 in 7154920.

On to step 1:
When dividing 7 by 236, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 236

Moving on to step 2:
236 can be fit into 71 0 times, resulting in a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (5) from the dividend to 71 and continue with: 715 / 236

Going ahead to step 3:
When dividing 715 by 236, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 3.0
If we take 708 away from 715, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 236

Let's proceed to step 4:
74 divided by 236 is 0 with a remainder of 74.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 74 to get 74.
Fetch the next digit (9) from the dividend, attach it to 74 and continue: 749 / 236

Going ahead to step 5:
236 goes into 749 3 times with a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 303.0
The remainder is 41 after subtracting 708 from 749.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 236

Moving on to step 6:
If we divide 412 by 236, we get 1 and a remainder of 176.
Use 1 as the next digit of our solution. 
Result so far: 3031.0
The remainder is 176 after subtracting 236 from 412.
Fetch the next digit (0) from the dividend, attach it to 176 and continue: 1760 / 236

Going ahead to step 7:
The number 236 fits into 1760 7 times, leaving a remainder of 108.
Record the quotient 7 as the next digit in the result. 
Result so far: 30317.0
Subtract 1652 from 1760 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 8:
1080 divided by 236 is 4 with a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 30317.4
If we subtract 944 from 1080, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 9:
The number 236 fits into 1360 5 times, leaving a remainder of 180.
Write down 5 as next digit of the result. 
Result so far: 30317.45
If we subtract 1180 from 1360, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
236 goes into 1800 7 times with a remainder of 148.
Put 7 as the next digit of the answer. 
Result so far: 30317.457
The remainder is 148 after subtracting 1652 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 11:
The number 236 fits into 1480 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 30317.4576
Subtract 1416 from 1480 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 12:
When dividing 640 by 236, we get 2 with a remainder of 168.
The next digit of our result is 2. 
Result so far: 30317.45762
Subtract 472 from 640 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 13:
The number 236 fits into 1680 7 times, leaving a remainder of 28.
The number 7 becomes the next digit in our result. 
Result so far: 30317.457627
If we take 1652 away from 1680, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 14:
When dividing 280 by 236, we get 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 30317.4576271
Deduct 236 from 280 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
236 can be fit into 440 1 times, resulting in a remainder of 204.
Put 1 as the next digit of the answer. 
Result so far: 30317.45762711
Subtract 236 from 440 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 30317.45762711, with a leftover of 2.04e-07.
