We divide 71520556 by 618
The aim is to understand the frequency of 618 in 71520556.

Step 1:
When dividing 7 by 618, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 618

Let's proceed to step 2:
The number 618 fits into 71 0 times, leaving a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Grab the next digit (5) from the dividend, add it to 71, then carry on: 715 / 618

Let's proceed to step 3:
715 divided by 618 is 1 with a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 618 from 715 leaves us with 97.
Bring next digit (2) of the dividend behind the 97 and repeat the process: 972 / 618

On to step 4:
If we divide 972 by 618, we get 1 and a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 354 after subtracting 618 from 972.
Append the next digit (0) from the dividend to 354 and continue with: 3540 / 618

Going ahead to step 5:
The number 618 fits into 3540 5 times, leaving a remainder of 450.
Put 5 as the next digit of the answer. 
Result so far: 115.0
If we take 3090 away from 3540, we end up with 450.
Take the next digit (5) from the dividend and append it to 450, then repeat: 4505 / 618

Step 6:
4505 divided by 618 is 7 with a remainder of 179.
Put 7 as the next digit of the answer. 
Result so far: 1157.0
Deduct 4326 from 4505 and we're left with 179.
Take the next digit (5) from the dividend and append it to 179, then repeat: 1795 / 618

Moving on to step 7:
The number 618 fits into 1795 2 times, leaving a remainder of 559.
The number 2 becomes the next digit in our result. 
Result so far: 11572.0
If we subtract 1236 from 1795, we get 559.
Grab the next digit (6) from the dividend, add it to 559, then carry on: 5596 / 618

Step 8:
When dividing 5596 by 618, we get 9 with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 115729.0
The remainder is 34 after subtracting 5562 from 5596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
618 goes into 340 0 times with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 115729.0
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
When dividing 3400 by 618, we get 5 with a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 115729.05
Deduct 3090 from 3400 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 11:
When dividing 3100 by 618, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 115729.055
The remainder is 10 after subtracting 3090 from 3100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 115729.055 with a remainder of 0.001.
