We look at the division of 7438662 by 236 
The aim is to understand the frequency of 236 in 7438662.

On to step 1:
7 divided by 236 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 236

Going ahead to step 2:
74 divided by 236 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Grab the next digit (3) from the dividend, add it to 74, then carry on: 743 / 236

Let's proceed to step 3:
236 can be fit into 743 3 times, resulting in a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 708 from 743 to get 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 236

Step 4:
358 divided by 236 is 1 with a remainder of 122.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we subtract 236 from 358, we get 122.
Bring next digit (6) of the dividend behind the 122 and repeat the process: 1226 / 236

Advancing to step 5:
236 can be fit into 1226 5 times, resulting in a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 315.0
Deduct 1180 from 1226 and we're left with 46.
Include the next digit (6) from the dividend after 46, then repeat: 466 / 236

Going ahead to step 6:
If we divide 466 by 236, we get 1 and a remainder of 230.
The number 1 becomes the next digit in our result. 
Result so far: 3151.0
Subtract 236 from 466 to get 230.
Grab the next digit (2) from the dividend, add it to 230, then carry on: 2302 / 236

Going ahead to step 7:
The number 236 fits into 2302 9 times, leaving a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 31519.0
Subtracting 2124 from 2302 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Advancing to step 8:
1780 divided by 236 is 7 with a remainder of 128.
Record the quotient 7 as the next digit in the result. 
Result so far: 31519.7
Subtract 1652 from 1780 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 9:
236 can be fit into 1280 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 31519.75
Subtract 1180 from 1280 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 10:
1000 divided by 236 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 31519.754
Subtracting 944 from 1000 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
236 can be fit into 560 2 times, resulting in a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 31519.7542
Subtracting 472 from 560 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 12:
236 goes into 880 3 times with a remainder of 172.
Write down 3 as next digit of the result. 
Result so far: 31519.75423
Deduct 708 from 880 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.

Moving on to step 13:
The number 236 fits into 1720 7 times, leaving a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 31519.754237
Subtract 1652 from 1720 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 14:
If we divide 680 by 236, we get 2 and a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 31519.7542372
If we subtract 472 from 680, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 15:
236 goes into 2080 8 times with a remainder of 192.
Put 8 as the next digit of the answer. 
Result so far: 31519.75423728
If we subtract 1888 from 2080, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The final result is 31519.75423728 with a remainder of 1.92e-07.
