Let's divide 31702680 by 814
The aim is to understand the frequency of 814 in 31702680.

On to step 1:
If we divide 3 by 814, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 814

Moving on to step 2:
814 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 814

Moving on to step 3:
814 can be fit into 317 0 times, resulting in a remainder of 317.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 317 and we're left with 317.
Include the next digit (0) from the dividend after 317, then repeat: 3170 / 814

Advancing to step 4:
814 can be fit into 3170 3 times, resulting in a remainder of 728.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 2442 from 3170 to get 728.
Include the next digit (2) from the dividend after 728, then repeat: 7282 / 814

On to step 5:
7282 divided by 814 is 8 with a remainder of 770.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 6512 from 7282 to get 770.
Grab the next digit (6) from the dividend, add it to 770, then carry on: 7706 / 814

Step 6:
When dividing 7706 by 814, we get 9 with a remainder of 380.
Put 9 as the next digit of the answer. 
Result so far: 389.0
Deduct 7326 from 7706 and we're left with 380.
Take the next digit (8) from the dividend and append it to 380, then repeat: 3808 / 814

Advancing to step 7:
When dividing 3808 by 814, we get 4 with a remainder of 552.
Put 4 as the next digit of the answer. 
Result so far: 3894.0
If we take 3256 away from 3808, we end up with 552.
Take the next digit (0) from the dividend and append it to 552, then repeat: 5520 / 814

Moving on to step 8:
814 goes into 5520 6 times with a remainder of 636.
Use 6 as the next digit of our solution. 
Result so far: 38946.0
If we subtract 4884 from 5520, we get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 9:
814 goes into 6360 7 times with a remainder of 662.
Use 7 as the next digit of our solution. 
Result so far: 38946.7
Subtracting 5698 from 6360 leaves us with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Going ahead to step 10:
The number 814 fits into 6620 8 times, leaving a remainder of 108.
Record the quotient 8 as the next digit in the result. 
Result so far: 38946.78
If we take 6512 away from 6620, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 11:
1080 divided by 814 is 1 with a remainder of 266.
Record the quotient 1 as the next digit in the result. 
Result so far: 38946.781
The remainder is 266 after subtracting 814 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 12:
814 goes into 2660 3 times with a remainder of 218.
The next digit of our result is 3. 
Result so far: 38946.7813
Deduct 2442 from 2660 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Going ahead to step 13:
814 can be fit into 2180 2 times, resulting in a remainder of 552.
Write down 2 as next digit of the result. 
Result so far: 38946.78132
Deduct 1628 from 2180 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 14:
5520 divided by 814 is 6 with a remainder of 636.
The next digit of our result is 6. 
Result so far: 38946.781326
Subtracting 4884 from 5520 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Let's proceed to step 15:
When dividing 6360 by 814, we get 7 with a remainder of 662.
Use 7 as the next digit of our solution. 
Result so far: 38946.7813267
Subtract 5698 from 6360 to get 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

Moving on to step 16:
814 can be fit into 6620 8 times, resulting in a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 38946.78132678
Subtracting 6512 from 6620 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 38946.78132678, with a leftover of 1.08e-07.
