We look at the division of 72073870 by 266 
The aim is to understand the frequency of 266 in 72073870.

Let's proceed to step 1:
7 divided by 266 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 266

Advancing to step 2:
266 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 266

Advancing to step 3:
720 divided by 266 is 2 with a remainder of 188.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 532 from 720 and we're left with 188.
Grab the next digit (7) from the dividend, add it to 188, then carry on: 1887 / 266

On to step 4:
266 can be fit into 1887 7 times, resulting in a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Deduct 1862 from 1887 and we're left with 25.
Grab the next digit (3) from the dividend, add it to 25, then carry on: 253 / 266

Moving on to step 5:
If we divide 253 by 266, we get 0 and a remainder of 253.
Put 0 as the next digit of the answer. 
Result so far: 270.0
If we take 0 away from 253, we end up with 253.
Bring next digit (8) of the dividend behind the 253 and repeat the process: 2538 / 266

On to step 6:
When dividing 2538 by 266, we get 9 with a remainder of 144.
Record the quotient 9 as the next digit in the result. 
Result so far: 2709.0
The remainder is 144 after subtracting 2394 from 2538.
Append the next digit (7) from the dividend to 144 and continue with: 1447 / 266

Step 7:
266 can be fit into 1447 5 times, resulting in a remainder of 117.
The next digit of our result is 5. 
Result so far: 27095.0
The remainder is 117 after subtracting 1330 from 1447.
Take the next digit (0) from the dividend and append it to 117, then repeat: 1170 / 266

Moving on to step 8:
266 goes into 1170 4 times with a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 270954.0
If we subtract 1064 from 1170, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
266 goes into 1060 3 times with a remainder of 262.
Record the quotient 3 as the next digit in the result. 
Result so far: 270954.3
Deduct 798 from 1060 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 10:
If we divide 2620 by 266, we get 9 and a remainder of 226.
Record the quotient 9 as the next digit in the result. 
Result so far: 270954.39
Subtract 2394 from 2620 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 11:
266 goes into 2260 8 times with a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 270954.398
If we take 2128 away from 2260, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
1320 divided by 266 is 4 with a remainder of 256.
The number 4 becomes the next digit in our result. 
Result so far: 270954.3984
If we subtract 1064 from 1320, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 13:
When dividing 2560 by 266, we get 9 with a remainder of 166.
The next digit of our result is 9. 
Result so far: 270954.39849
The remainder is 166 after subtracting 2394 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 14:
The number 266 fits into 1660 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 270954.398496
Deduct 1596 from 1660 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
266 can be fit into 640 2 times, resulting in a remainder of 108.
Use 2 as the next digit of our solution. 
Result so far: 270954.3984962
If we subtract 532 from 640, we 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.

Step 16:
If we divide 1080 by 266, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 270954.39849624
If we subtract 1064 from 1080, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 270954.39849624, and the remainder is 1.6e-08.
