918635 ÷ 39 
The aim is to understand the frequency of 39 in 918635.

Moving on to step 1:
The number 39 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 39

Step 2:
39 goes into 91 2 times with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 78 away from 91, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 39

Moving on to step 3:
When dividing 138 by 39, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 117 from 138 leaves us with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 39

On to step 4:
216 divided by 39 is 5 with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 235.0
If we subtract 195 from 216, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 39

On to step 5:
When dividing 213 by 39, we get 5 with a remainder of 18.
The next digit of our result is 5. 
Result so far: 2355.0
If we subtract 195 from 213, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 39

On to step 6:
When dividing 185 by 39, we get 4 with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 23554.0
Subtract 156 from 185 to 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.

On to step 7:
If we divide 290 by 39, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 23554.7
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.

On to step 8:
When dividing 170 by 39, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 23554.74
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
39 can be fit into 140 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 23554.743
If we take 117 away from 140, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 10:
230 divided by 39 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 23554.7435
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
When dividing 350 by 39, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 23554.74358
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.

Advancing to step 12:
When dividing 380 by 39, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 23554.743589
Subtract 351 from 380 to 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:
290 divided by 39 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 23554.7435897
Subtract 273 from 290 to 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.

Let's proceed to step 14:
If we divide 170 by 39, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 23554.74358974
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.

The final outcome is 23554.74358974, with a leftover of 1.4e-08.
