We look at the division of 71401370 by 818 
The aim is to understand the frequency of 818 in 71401370.

Step 1:
818 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 818

Advancing to step 2:
71 divided by 818 is 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (4) from the dividend after 71, then repeat: 714 / 818

Moving on to step 3:
When dividing 714 by 818, we get 0 with a remainder of 714.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 714, we get 714.
Take the next digit (0) from the dividend and append it to 714, then repeat: 7140 / 818

On to step 4:
The number 818 fits into 7140 8 times, leaving a remainder of 596.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6544 away from 7140, we end up with 596.
Fetch the next digit (1) from the dividend, attach it to 596 and continue: 5961 / 818

Advancing to step 5:
When dividing 5961 by 818, we get 7 with a remainder of 235.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 5726 from 5961 to get 235.
Bring next digit (3) of the dividend behind the 235 and repeat the process: 2353 / 818

Moving on to step 6:
818 can be fit into 2353 2 times, resulting in a remainder of 717.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
Deduct 1636 from 2353 and we're left with 717.
Fetch the next digit (7) from the dividend, attach it to 717 and continue: 7177 / 818

Let's proceed to step 7:
The number 818 fits into 7177 8 times, leaving a remainder of 633.
Use 8 as the next digit of our solution. 
Result so far: 8728.0
Subtract 6544 from 7177 to get 633.
Grab the next digit (0) from the dividend, add it to 633, then carry on: 6330 / 818

Let's proceed to step 8:
6330 divided by 818 is 7 with a remainder of 604.
Record the quotient 7 as the next digit in the result. 
Result so far: 87287.0
Subtract 5726 from 6330 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 9:
818 goes into 6040 7 times with a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 87287.7
If we take 5726 away from 6040, we end up 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.

Moving on to step 10:
The number 818 fits into 3140 3 times, leaving a remainder of 686.
Put 3 as the next digit of the answer. 
Result so far: 87287.73
Subtracting 2454 from 3140 leaves us with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

Moving on to step 11:
6860 divided by 818 is 8 with a remainder of 316.
Use 8 as the next digit of our solution. 
Result so far: 87287.738
Subtract 6544 from 6860 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 12:
818 goes into 3160 3 times with a remainder of 706.
Write down 3 as next digit of the result. 
Result so far: 87287.7383
Subtracting 2454 from 3160 leaves us with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

On to step 13:
The number 818 fits into 7060 8 times, leaving a remainder of 516.
The next digit of our result is 8. 
Result so far: 87287.73838
If we subtract 6544 from 7060, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Going ahead to step 14:
818 can be fit into 5160 6 times, resulting in a remainder of 252.
Record the quotient 6 as the next digit in the result. 
Result so far: 87287.738386
The remainder is 252 after subtracting 4908 from 5160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 15:
2520 divided by 818 is 3 with a remainder of 66.
Put 3 as the next digit of the answer. 
Result so far: 87287.7383863
Subtract 2454 from 2520 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 16:
818 goes into 660 0 times with a remainder of 660.
Write down 0 as next digit of the result. 
Result so far: 87287.7383863
If we take 0 away from 660, we end up with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

The quotient of the division is 87287.7383863, and the remainder is 6.6e-07.
