We're dividing 908724 by 39 
The aim is to understand the frequency of 39 in 908724.

Moving on to step 1:
9 divided by 39 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 39

On to step 2:
If we divide 90 by 39, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 78 away from 90, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 39

Step 3:
If we divide 128 by 39, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 117 from 128 leaves us with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 39

Moving on to step 4:
39 can be fit into 117 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 233.0
Deduct 117 from 117 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 39

Moving on to step 5:
The number 39 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 2330.0
If we subtract 0 from 2, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 39

Advancing to step 6:
When dividing 24 by 39, we get 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 23300.0
Deduct 0 from 24 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 23300.6
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
39 goes into 60 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 23300.61
If we subtract 39 from 60, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
If we divide 210 by 39, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 23300.615
The remainder is 15 after subtracting 195 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
The number 39 fits into 150 3 times, leaving a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 23300.6153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 11:
When dividing 330 by 39, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 23300.61538
Subtracting 312 from 330 leaves us 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.

Let's proceed to step 12:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 23300.615384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 23300.6153846
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
If we divide 60 by 39, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 23300.61538461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 23300.61538461 with a remainder of 2.1e-08.
