We divide 12497437 by 851
The aim is to understand the frequency of 851 in 12497437.

On to step 1:
1 divided by 851 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 851

On to step 2:
When dividing 12 by 851, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 851

Going ahead to step 3:
851 can be fit into 124 0 times, resulting in a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 124, we get 124.
Include the next digit (9) from the dividend after 124, then repeat: 1249 / 851

On to step 4:
1249 divided by 851 is 1 with a remainder of 398.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 398 after subtracting 851 from 1249.
Fetch the next digit (7) from the dividend, attach it to 398 and continue: 3987 / 851

Let's proceed to step 5:
851 goes into 3987 4 times with a remainder of 583.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 3404 from 3987 to get 583.
Append the next digit (4) from the dividend to 583 and continue with: 5834 / 851

Step 6:
851 can be fit into 5834 6 times, resulting in a remainder of 728.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
If we subtract 5106 from 5834, we get 728.
Append the next digit (3) from the dividend to 728 and continue with: 7283 / 851

Going ahead to step 7:
851 can be fit into 7283 8 times, resulting in a remainder of 475.
The number 8 becomes the next digit in our result. 
Result so far: 1468.0
If we subtract 6808 from 7283, we get 475.
Include the next digit (7) from the dividend after 475, then repeat: 4757 / 851

On to step 8:
If we divide 4757 by 851, we get 5 and a remainder of 502.
Put 5 as the next digit of the answer. 
Result so far: 14685.0
The remainder is 502 after subtracting 4255 from 4757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Going ahead to step 9:
If we divide 5020 by 851, we get 5 and a remainder of 765.
Write down 5 as next digit of the result. 
Result so far: 14685.5
Subtract 4255 from 5020 to get 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

Let's proceed to step 10:
The number 851 fits into 7650 8 times, leaving a remainder of 842.
The next digit of our result is 8. 
Result so far: 14685.58
If we take 6808 away from 7650, we end up with 842.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8420, and continue the process.

Let's proceed to step 11:
851 can be fit into 8420 9 times, resulting in a remainder of 761.
Use 9 as the next digit of our solution. 
Result so far: 14685.589
Subtracting 7659 from 8420 leaves us with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

On to step 12:
851 goes into 7610 8 times with a remainder of 802.
Write down 8 as next digit of the result. 
Result so far: 14685.5898
If we subtract 6808 from 7610, we get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

Moving on to step 13:
851 goes into 8020 9 times with a remainder of 361.
The next digit of our result is 9. 
Result so far: 14685.58989
Deduct 7659 from 8020 and we're left with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Let's proceed to step 14:
The number 851 fits into 3610 4 times, leaving a remainder of 206.
The next digit of our result is 4. 
Result so far: 14685.589894
Subtract 3404 from 3610 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 15:
2060 divided by 851 is 2 with a remainder of 358.
Record the quotient 2 as the next digit in the result. 
Result so far: 14685.5898942
If we subtract 1702 from 2060, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

On to step 16:
851 can be fit into 3580 4 times, resulting in a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 14685.58989424
If we take 3404 away from 3580, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

In conclusion, the division gives 14685.58989424 with a balance of 1.76e-07.
