90826137 ÷ 39 
The aim is to understand the frequency of 39 in 90826137.

Let's proceed to step 1:
9 divided by 39 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 39

Going ahead to step 2:
When dividing 90 by 39, we get 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 12 after subtracting 78 from 90.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 39

On to step 3:
When dividing 128 by 39, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 117 from 128, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 39

Let's proceed to step 4:
The number 39 fits into 112 2 times, leaving a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
If we take 78 away from 112, we end up with 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 39

Advancing to step 5:
If we divide 346 by 39, we get 8 and a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 2328.0
The remainder is 34 after subtracting 312 from 346.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 39

Moving on to step 6:
If we divide 341 by 39, we get 8 and a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 23288.0
Subtract 312 from 341 to get 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 39

Advancing to step 7:
When dividing 293 by 39, we get 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 232887.0
Deduct 273 from 293 and we're left with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 39

Step 8:
207 divided by 39 is 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 2328875.0
Subtract 195 from 207 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
The number 39 fits into 120 3 times, leaving a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 2328875.3
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
30 divided by 39 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2328875.3
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
If we divide 300 by 39, we get 7 and a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 2328875.307
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 12:
When dividing 270 by 39, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 2328875.3076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 2328875.30769
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 14:
If we divide 90 by 39, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2328875.307692
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 15:
If we divide 120 by 39, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 2328875.3076923
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 16:
30 divided by 39 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 2328875.3076923
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 2328875.3076923 with a remaining 3e-08.
