We're dividing 39438147 by 910 
The aim is to understand the frequency of 910 in 39438147.

Step 1:
If we divide 3 by 910, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 910

Going ahead to step 2:
910 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 910

Moving on to step 3:
910 can be fit into 394 0 times, resulting in a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 394 and we're left with 394.
Take the next digit (3) from the dividend and append it to 394, then repeat: 3943 / 910

Going ahead to step 4:
When dividing 3943 by 910, we get 4 with a remainder of 303.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3640 away from 3943, we end up with 303.
Bring next digit (8) of the dividend behind the 303 and repeat the process: 3038 / 910

Moving on to step 5:
910 goes into 3038 3 times with a remainder of 308.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 2730 from 3038, we get 308.
Grab the next digit (1) from the dividend, add it to 308, then carry on: 3081 / 910

Let's proceed to step 6:
3081 divided by 910 is 3 with a remainder of 351.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
If we take 2730 away from 3081, we end up with 351.
Append the next digit (4) from the dividend to 351 and continue with: 3514 / 910

Moving on to step 7:
The number 910 fits into 3514 3 times, leaving a remainder of 784.
Put 3 as the next digit of the answer. 
Result so far: 4333.0
If we subtract 2730 from 3514, we get 784.
Bring next digit (7) of the dividend behind the 784 and repeat the process: 7847 / 910

Advancing to step 8:
910 can be fit into 7847 8 times, resulting in a remainder of 567.
Use 8 as the next digit of our solution. 
Result so far: 43338.0
Subtract 7280 from 7847 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Moving on to step 9:
910 goes into 5670 6 times with a remainder of 210.
The next digit of our result is 6. 
Result so far: 43338.6
Deduct 5460 from 5670 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
If we divide 2100 by 910, we get 2 and a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 43338.62
If we take 1820 away from 2100, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
If we divide 2800 by 910, we get 3 and a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 43338.623
The remainder is 70 after subtracting 2730 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
910 goes into 700 0 times with a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 43338.623
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 13:
The number 910 fits into 7000 7 times, leaving a remainder of 630.
Use 7 as the next digit of our solution. 
Result so far: 43338.62307
The remainder is 630 after subtracting 6370 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 14:
If we divide 6300 by 910, we get 6 and a remainder of 840.
The next digit of our result is 6. 
Result so far: 43338.623076
Subtract 5460 from 6300 to get 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8400, and continue the process.

Let's proceed to step 15:
If we divide 8400 by 910, we get 9 and a remainder of 210.
The number 9 becomes the next digit in our result. 
Result so far: 43338.6230769
Subtract 8190 from 8400 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 16:
2100 divided by 910 is 2 with a remainder of 280.
Record the quotient 2 as the next digit in the result. 
Result so far: 43338.62307692
Deduct 1820 from 2100 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 43338.62307692 and a remainder of 2.8e-07.
