266945 ÷ 39 
The aim is to understand the frequency of 39 in 266945.

Moving on to step 1:
The number 39 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 39

On to step 2:
The number 39 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 39

Step 3:
39 can be fit into 266 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 234 from 266 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 39

On to step 4:
The number 39 fits into 329 8 times, leaving a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Deduct 312 from 329 and we're left with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 39

On to step 5:
The number 39 fits into 174 4 times, leaving a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 684.0
If we take 156 away from 174, we end up with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 39

Let's proceed to step 6:
The number 39 fits into 185 4 times, leaving a remainder of 29.
The next digit of our result is 4. 
Result so far: 6844.0
Deduct 156 from 185 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
290 divided by 39 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 6844.7
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
If we divide 170 by 39, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 6844.74
Subtracting 156 from 170 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 39, we get 3 and a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 6844.743
Subtract 117 from 140 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 10:
When dividing 230 by 39, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 6844.7435
If we subtract 195 from 230, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 11:
If we divide 350 by 39, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 6844.74358
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
39 goes into 380 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 6844.743589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
If we divide 290 by 39, we get 7 and a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 6844.7435897
If we subtract 273 from 290, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
170 divided by 39 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 6844.74358974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 6844.74358974 with a balance of 1.4e-08.
