Let's divide 9188521 by 618
The aim is to understand the frequency of 618 in 9188521.

Moving on to step 1:
When dividing 9 by 618, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 618

Let's proceed to step 2:
When dividing 91 by 618, we get 0 with a remainder of 91.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Fetch the next digit (8) from the dividend, attach it to 91 and continue: 918 / 618

Advancing to step 3:
618 goes into 918 1 times with a remainder of 300.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 618 from 918 to get 300.
Bring next digit (8) of the dividend behind the 300 and repeat the process: 3008 / 618

On to step 4:
618 goes into 3008 4 times with a remainder of 536.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 2472 from 3008 to get 536.
Take the next digit (5) from the dividend and append it to 536, then repeat: 5365 / 618

On to step 5:
The number 618 fits into 5365 8 times, leaving a remainder of 421.
Record the quotient 8 as the next digit in the result. 
Result so far: 148.0
If we subtract 4944 from 5365, we get 421.
Append the next digit (2) from the dividend to 421 and continue with: 4212 / 618

Advancing to step 6:
618 goes into 4212 6 times with a remainder of 504.
The next digit of our result is 6. 
Result so far: 1486.0
Deduct 3708 from 4212 and we're left with 504.
Fetch the next digit (1) from the dividend, attach it to 504 and continue: 5041 / 618

Going ahead to step 7:
5041 divided by 618 is 8 with a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 14868.0
Subtracting 4944 from 5041 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 8:
618 can be fit into 970 1 times, resulting in a remainder of 352.
Write down 1 as next digit of the result. 
Result so far: 14868.1
The remainder is 352 after subtracting 618 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 9:
If we divide 3520 by 618, we get 5 and a remainder of 430.
Record the quotient 5 as the next digit in the result. 
Result so far: 14868.15
Subtracting 3090 from 3520 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 10:
If we divide 4300 by 618, we get 6 and a remainder of 592.
Use 6 as the next digit of our solution. 
Result so far: 14868.156
The remainder is 592 after subtracting 3708 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 11:
5920 divided by 618 is 9 with a remainder of 358.
Use 9 as the next digit of our solution. 
Result so far: 14868.1569
Deduct 5562 from 5920 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Advancing to step 12:
618 can be fit into 3580 5 times, resulting in a remainder of 490.
The number 5 becomes the next digit in our result. 
Result so far: 14868.15695
Subtract 3090 from 3580 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Step 13:
When dividing 4900 by 618, we get 7 with a remainder of 574.
Use 7 as the next digit of our solution. 
Result so far: 14868.156957
The remainder is 574 after subtracting 4326 from 4900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Advancing to step 14:
The number 618 fits into 5740 9 times, leaving a remainder of 178.
The number 9 becomes the next digit in our result. 
Result so far: 14868.1569579
The remainder is 178 after subtracting 5562 from 5740.
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 15:
1780 divided by 618 is 2 with a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 14868.15695792
Subtract 1236 from 1780 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

After the division, we end up with 14868.15695792 and a remainder of 5.44e-07.
