We look at the division of 78721210 by 118 
The aim is to understand the frequency of 118 in 78721210.

Let's proceed to step 1:
The number 118 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 118

Moving on to step 2:
The number 118 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 118

Let's proceed to step 3:
787 divided by 118 is 6 with a remainder of 79.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 708 away from 787, we end up with 79.
Fetch the next digit (2) from the dividend, attach it to 79 and continue: 792 / 118

Advancing to step 4:
792 divided by 118 is 6 with a remainder of 84.
The next digit of our result is 6. 
Result so far: 66.0
If we take 708 away from 792, we end up with 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 118

On to step 5:
The number 118 fits into 841 7 times, leaving a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 667.0
If we subtract 826 from 841, we get 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 118

Let's proceed to step 6:
118 can be fit into 152 1 times, resulting in a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 6671.0
Subtract 118 from 152 to get 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 118

Moving on to step 7:
118 can be fit into 341 2 times, resulting in a remainder of 105.
Put 2 as the next digit of the answer. 
Result so far: 66712.0
The remainder is 105 after subtracting 236 from 341.
Bring next digit (0) of the dividend behind the 105 and repeat the process: 1050 / 118

On to step 8:
1050 divided by 118 is 8 with a remainder of 106.
The number 8 becomes the next digit in our result. 
Result so far: 667128.0
The remainder is 106 after subtracting 944 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 9:
118 can be fit into 1060 8 times, resulting in a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 667128.8
If we take 944 away from 1060, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 10:
118 can be fit into 1160 9 times, resulting in a remainder of 98.
Use 9 as the next digit of our solution. 
Result so far: 667128.89
Subtracting 1062 from 1160 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 11:
When dividing 980 by 118, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 667128.898
If we take 944 away from 980, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
118 goes into 360 3 times with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 667128.8983
If we subtract 354 from 360, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
When dividing 60 by 118, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 667128.8983
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 14:
600 divided by 118 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 667128.898305
The remainder is 10 after subtracting 590 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 15:
If we divide 100 by 118, we get 0 and a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 667128.898305
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 16:
If we divide 1000 by 118, we get 8 and a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 667128.89830508
The remainder is 56 after subtracting 944 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 667128.89830508 with a remaining 5.6e-08.
