We look at the division of 39034210 by 814 
The aim is to understand the frequency of 814 in 39034210.

Let's proceed to step 1:
814 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 814

Going ahead to step 2:
814 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 814

Advancing to step 3:
The number 814 fits into 390 0 times, leaving a remainder of 390.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 390 after subtracting 0 from 390.
Bring next digit (3) of the dividend behind the 390 and repeat the process: 3903 / 814

Step 4:
The number 814 fits into 3903 4 times, leaving a remainder of 647.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3256 away from 3903, we end up with 647.
Grab the next digit (4) from the dividend, add it to 647, then carry on: 6474 / 814

Moving on to step 5:
6474 divided by 814 is 7 with a remainder of 776.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 5698 away from 6474, we end up with 776.
Include the next digit (2) from the dividend after 776, then repeat: 7762 / 814

On to step 6:
The number 814 fits into 7762 9 times, leaving a remainder of 436.
The next digit of our result is 9. 
Result so far: 479.0
If we subtract 7326 from 7762, we get 436.
Append the next digit (1) from the dividend to 436 and continue with: 4361 / 814

On to step 7:
4361 divided by 814 is 5 with a remainder of 291.
Use 5 as the next digit of our solution. 
Result so far: 4795.0
If we take 4070 away from 4361, we end up with 291.
Fetch the next digit (0) from the dividend, attach it to 291 and continue: 2910 / 814

Advancing to step 8:
814 can be fit into 2910 3 times, resulting in a remainder of 468.
Put 3 as the next digit of the answer. 
Result so far: 47953.0
Deduct 2442 from 2910 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 9:
When dividing 4680 by 814, we get 5 with a remainder of 610.
Put 5 as the next digit of the answer. 
Result so far: 47953.5
Subtract 4070 from 4680 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 10:
6100 divided by 814 is 7 with a remainder of 402.
The next digit of our result is 7. 
Result so far: 47953.57
The remainder is 402 after subtracting 5698 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 11:
When dividing 4020 by 814, we get 4 with a remainder of 764.
Record the quotient 4 as the next digit in the result. 
Result so far: 47953.574
Subtract 3256 from 4020 to get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

On to step 12:
814 can be fit into 7640 9 times, resulting in a remainder of 314.
Record the quotient 9 as the next digit in the result. 
Result so far: 47953.5749
Deduct 7326 from 7640 and we're left with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Going ahead to step 13:
The number 814 fits into 3140 3 times, leaving a remainder of 698.
Use 3 as the next digit of our solution. 
Result so far: 47953.57493
The remainder is 698 after subtracting 2442 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Let's proceed to step 14:
The number 814 fits into 6980 8 times, leaving a remainder of 468.
Use 8 as the next digit of our solution. 
Result so far: 47953.574938
Subtract 6512 from 6980 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 15:
4680 divided by 814 is 5 with a remainder of 610.
Write down 5 as next digit of the result. 
Result so far: 47953.5749385
If we subtract 4070 from 4680, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Going ahead to step 16:
If we divide 6100 by 814, we get 7 and a remainder of 402.
Record the quotient 7 as the next digit in the result. 
Result so far: 47953.57493857
Subtract 5698 from 6100 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

The final result is 47953.57493857 with a remainder of 4.02e-07.
