We look at the division of 42240671 by 814 
The aim is to understand the frequency of 814 in 42240671.

On to step 1:
The number 814 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 814

Advancing to step 2:
42 divided by 814 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 814

On to step 3:
814 can be fit into 422 0 times, resulting in a remainder of 422.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 422 to get 422.
Include the next digit (4) from the dividend after 422, then repeat: 4224 / 814

Going ahead to step 4:
814 goes into 4224 5 times with a remainder of 154.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4070 from 4224 and we're left with 154.
Grab the next digit (0) from the dividend, add it to 154, then carry on: 1540 / 814

Step 5:
When dividing 1540 by 814, we get 1 with a remainder of 726.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 814 from 1540 to get 726.
Bring next digit (6) of the dividend behind the 726 and repeat the process: 7266 / 814

Going ahead to step 6:
If we divide 7266 by 814, we get 8 and a remainder of 754.
Record the quotient 8 as the next digit in the result. 
Result so far: 518.0
Subtract 6512 from 7266 to get 754.
Bring next digit (7) of the dividend behind the 754 and repeat the process: 7547 / 814

Let's proceed to step 7:
When dividing 7547 by 814, we get 9 with a remainder of 221.
The next digit of our result is 9. 
Result so far: 5189.0
Deduct 7326 from 7547 and we're left with 221.
Append the next digit (1) from the dividend to 221 and continue with: 2211 / 814

Let's proceed to step 8:
814 goes into 2211 2 times with a remainder of 583.
Record the quotient 2 as the next digit in the result. 
Result so far: 51892.0
Subtracting 1628 from 2211 leaves us with 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Going ahead to step 9:
814 can be fit into 5830 7 times, resulting in a remainder of 132.
Put 7 as the next digit of the answer. 
Result so far: 51892.7
Subtract 5698 from 5830 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 10:
814 goes into 1320 1 times with a remainder of 506.
Write down 1 as next digit of the result. 
Result so far: 51892.71
The remainder is 506 after subtracting 814 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 11:
The number 814 fits into 5060 6 times, leaving a remainder of 176.
The number 6 becomes the next digit in our result. 
Result so far: 51892.716
Subtracting 4884 from 5060 leaves us 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.

Let's proceed to step 12:
When dividing 1760 by 814, we get 2 with a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 51892.7162
If we take 1628 away from 1760, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 13:
1320 divided by 814 is 1 with a remainder of 506.
Use 1 as the next digit of our solution. 
Result so far: 51892.71621
Deduct 814 from 1320 and we're left with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Moving on to step 14:
The number 814 fits into 5060 6 times, leaving a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 51892.716216
If we subtract 4884 from 5060, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 15:
The number 814 fits into 1760 2 times, leaving a remainder of 132.
The next digit of our result is 2. 
Result so far: 51892.7162162
Subtracting 1628 from 1760 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 16:
814 can be fit into 1320 1 times, resulting in a remainder of 506.
Record the quotient 1 as the next digit in the result. 
Result so far: 51892.71621621
The remainder is 506 after subtracting 814 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

The quotient of the division is 51892.71621621, and the remainder is 5.06e-07.
