We're dividing 39865442 by 266 
The aim is to understand the frequency of 266 in 39865442.

Moving on to step 1:
When dividing 3 by 266, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 266

Moving on to step 2:
When dividing 39 by 266, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 266

Moving on to step 3:
398 divided by 266 is 1 with a remainder of 132.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 266 from 398 and we're left with 132.
Fetch the next digit (6) from the dividend, attach it to 132 and continue: 1326 / 266

On to step 4:
1326 divided by 266 is 4 with a remainder of 262.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 1064 from 1326 to get 262.
Grab the next digit (5) from the dividend, add it to 262, then carry on: 2625 / 266

Let's proceed to step 5:
2625 divided by 266 is 9 with a remainder of 231.
The number 9 becomes the next digit in our result. 
Result so far: 149.0
If we subtract 2394 from 2625, we get 231.
Append the next digit (4) from the dividend to 231 and continue with: 2314 / 266

On to step 6:
The number 266 fits into 2314 8 times, leaving a remainder of 186.
Use 8 as the next digit of our solution. 
Result so far: 1498.0
Deduct 2128 from 2314 and we're left with 186.
Grab the next digit (4) from the dividend, add it to 186, then carry on: 1864 / 266

Advancing to step 7:
266 can be fit into 1864 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 14987.0
Deduct 1862 from 1864 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 266

Advancing to step 8:
266 goes into 22 0 times with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 149870.0
The remainder is 22 after subtracting 0 from 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
If we divide 220 by 266, we get 0 and a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 149870.0
If we subtract 0 from 220, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
The number 266 fits into 2200 8 times, leaving a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 149870.08
Subtracting 2128 from 2200 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 11:
720 divided by 266 is 2 with a remainder of 188.
The next digit of our result is 2. 
Result so far: 149870.082
If we subtract 532 from 720, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 12:
266 can be fit into 1880 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 149870.0827
If we take 1862 away from 1880, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
266 can be fit into 180 0 times, resulting in a remainder of 180.
The next digit of our result is 0. 
Result so far: 149870.0827
The remainder is 180 after subtracting 0 from 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 14:
1800 divided by 266 is 6 with a remainder of 204.
The next digit of our result is 6. 
Result so far: 149870.082706
The remainder is 204 after subtracting 1596 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 15:
The number 266 fits into 2040 7 times, leaving a remainder of 178.
The number 7 becomes the next digit in our result. 
Result so far: 149870.0827067
If we take 1862 away from 2040, we end up 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.

Moving on to step 16:
The number 266 fits into 1780 6 times, leaving a remainder of 184.
Write down 6 as next digit of the result. 
Result so far: 149870.08270676
Subtract 1596 from 1780 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Our division results in 149870.08270676 with a remaining 1.84e-07.
