We're dividing 70508018 by 814 
The aim is to understand the frequency of 814 in 70508018.

On to step 1:
When dividing 7 by 814, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 814

Advancing to step 2:
When dividing 70 by 814, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Include the next digit (5) from the dividend after 70, then repeat: 705 / 814

Step 3:
The number 814 fits into 705 0 times, leaving a remainder of 705.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 705, we end up with 705.
Take the next digit (0) from the dividend and append it to 705, then repeat: 7050 / 814

Moving on to step 4:
The number 814 fits into 7050 8 times, leaving a remainder of 538.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 538 after subtracting 6512 from 7050.
Grab the next digit (8) from the dividend, add it to 538, then carry on: 5388 / 814

Going ahead to step 5:
If we divide 5388 by 814, we get 6 and a remainder of 504.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 4884 from 5388, we get 504.
Fetch the next digit (0) from the dividend, attach it to 504 and continue: 5040 / 814

Moving on to step 6:
5040 divided by 814 is 6 with a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 866.0
Deduct 4884 from 5040 and we're left with 156.
Bring next digit (1) of the dividend behind the 156 and repeat the process: 1561 / 814

Let's proceed to step 7:
1561 divided by 814 is 1 with a remainder of 747.
Record the quotient 1 as the next digit in the result. 
Result so far: 8661.0
The remainder is 747 after subtracting 814 from 1561.
Take the next digit (8) from the dividend and append it to 747, then repeat: 7478 / 814

Moving on to step 8:
The number 814 fits into 7478 9 times, leaving a remainder of 152.
The number 9 becomes the next digit in our result. 
Result so far: 86619.0
Subtract 7326 from 7478 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 9:
The number 814 fits into 1520 1 times, leaving a remainder of 706.
Write down 1 as next digit of the result. 
Result so far: 86619.1
The remainder is 706 after subtracting 814 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Moving on to step 10:
814 can be fit into 7060 8 times, resulting in a remainder of 548.
The number 8 becomes the next digit in our result. 
Result so far: 86619.18
Deduct 6512 from 7060 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 11:
If we divide 5480 by 814, we get 6 and a remainder of 596.
Put 6 as the next digit of the answer. 
Result so far: 86619.186
If we take 4884 away from 5480, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 12:
5960 divided by 814 is 7 with a remainder of 262.
The next digit of our result is 7. 
Result so far: 86619.1867
The remainder is 262 after subtracting 5698 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 13:
814 goes into 2620 3 times with a remainder of 178.
Use 3 as the next digit of our solution. 
Result so far: 86619.18673
If we take 2442 away from 2620, we end up with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 14:
1780 divided by 814 is 2 with a remainder of 152.
The number 2 becomes the next digit in our result. 
Result so far: 86619.186732
If we subtract 1628 from 1780, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 15:
If we divide 1520 by 814, we get 1 and a remainder of 706.
Record the quotient 1 as the next digit in the result. 
Result so far: 86619.1867321
If we subtract 814 from 1520, we get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Moving on to step 16:
7060 divided by 814 is 8 with a remainder of 548.
Record the quotient 8 as the next digit in the result. 
Result so far: 86619.18673218
Deduct 6512 from 7060 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The final result is 86619.18673218 with a remainder of 5.48e-07.
