552805 ÷ 39 
The aim is to understand the frequency of 39 in 552805.

Step 1:
When dividing 5 by 39, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 39

Going ahead to step 2:
The number 39 fits into 55 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 39 from 55 to get 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 39

Step 3:
If we divide 162 by 39, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 156 from 162 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 39

Advancing to step 4:
When dividing 68 by 39, we get 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 141.0
Subtract 39 from 68 to get 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 39

Going ahead to step 5:
When dividing 290 by 39, we get 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 1417.0
Subtract 273 from 290 to get 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 39

Step 6:
175 divided by 39 is 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 14174.0
Subtract 156 from 175 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
190 divided by 39 is 4 with a remainder of 34.
The next digit of our result is 4. 
Result so far: 14174.4
If we take 156 away from 190, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 14174.48
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
If we divide 280 by 39, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 14174.487
If we take 273 away from 280, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
If we divide 70 by 39, we get 1 and a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 14174.4871
Subtract 39 from 70 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
310 divided by 39 is 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 14174.48717
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
If we divide 370 by 39, we get 9 and a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 14174.487179
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 13:
When dividing 190 by 39, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 14174.4871794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 14174.48717948
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 14174.48717948, with a leftover of 2.8e-08.
