We look at the division of 168748 by 39 
The aim is to understand the frequency of 39 in 168748.

Going ahead to step 1:
The number 39 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 39

On to step 2:
39 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 39

On to step 3:
39 can be fit into 168 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 156 from 168 and we're left with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 39

Moving on to step 4:
39 can be fit into 127 3 times, resulting in a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Deduct 117 from 127 and we're left with 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 39

Going ahead to step 5:
The number 39 fits into 104 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 432.0
If we take 78 away from 104, we end up with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 39

Let's proceed to step 6:
268 divided by 39 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 4326.0
Subtracting 234 from 268 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 7:
39 goes into 340 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 4326.8
If we subtract 312 from 340, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 8:
39 can be fit into 280 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 4326.87
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 9:
The number 39 fits into 70 1 times, leaving a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 4326.871
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.

Step 10:
39 can be fit into 310 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 4326.8717
Deduct 273 from 310 and we're left 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.

On to step 11:
370 divided by 39 is 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 4326.87179
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.

Going ahead to step 12:
If we divide 190 by 39, we get 4 and a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 4326.871794
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.

Moving on to step 13:
The number 39 fits into 340 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 4326.8717948
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.

Let's proceed to step 14:
280 divided by 39 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 4326.87179487
Subtracting 273 from 280 leaves us 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.

After the division, we end up with 4326.87179487 and a remainder of 7e-09.
