We look at the division of 74372561 by 618 
The aim is to understand the frequency of 618 in 74372561.

Let's proceed to step 1:
If we divide 7 by 618, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 618

Step 2:
The number 618 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Take the next digit (3) from the dividend and append it to 74, then repeat: 743 / 618

Let's proceed to step 3:
618 goes into 743 1 times with a remainder of 125.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 618 away from 743, we end up with 125.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 618

Step 4:
618 goes into 1257 2 times with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1236 from 1257 to get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 618

On to step 5:
212 divided by 618 is 0 with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Deduct 0 from 212 and we're left with 212.
Fetch the next digit (5) from the dividend, attach it to 212 and continue: 2125 / 618

On to step 6:
618 can be fit into 2125 3 times, resulting in a remainder of 271.
The number 3 becomes the next digit in our result. 
Result so far: 1203.0
Deduct 1854 from 2125 and we're left with 271.
Append the next digit (6) from the dividend to 271 and continue with: 2716 / 618

Let's proceed to step 7:
The number 618 fits into 2716 4 times, leaving a remainder of 244.
Put 4 as the next digit of the answer. 
Result so far: 12034.0
Subtract 2472 from 2716 to get 244.
Take the next digit (1) from the dividend and append it to 244, then repeat: 2441 / 618

On to step 8:
2441 divided by 618 is 3 with a remainder of 587.
The next digit of our result is 3. 
Result so far: 120343.0
If we subtract 1854 from 2441, we get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 9:
When dividing 5870 by 618, we get 9 with a remainder of 308.
Write down 9 as next digit of the result. 
Result so far: 120343.9
Deduct 5562 from 5870 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 10:
3080 divided by 618 is 4 with a remainder of 608.
The next digit of our result is 4. 
Result so far: 120343.94
If we take 2472 away from 3080, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 11:
618 goes into 6080 9 times with a remainder of 518.
Put 9 as the next digit of the answer. 
Result so far: 120343.949
Subtracting 5562 from 6080 leaves us with 518.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

On to step 12:
618 goes into 5180 8 times with a remainder of 236.
Use 8 as the next digit of our solution. 
Result so far: 120343.9498
Subtracting 4944 from 5180 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 13:
If we divide 2360 by 618, we get 3 and a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 120343.94983
Subtract 1854 from 2360 to get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Moving on to step 14:
When dividing 5060 by 618, we get 8 with a remainder of 116.
Record the quotient 8 as the next digit in the result. 
Result so far: 120343.949838
If we take 4944 away from 5060, 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.

Advancing to step 15:
The number 618 fits into 1160 1 times, leaving a remainder of 542.
Record the quotient 1 as the next digit in the result. 
Result so far: 120343.9498381
If we subtract 618 from 1160, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Advancing to step 16:
618 goes into 5420 8 times with a remainder of 476.
Put 8 as the next digit of the answer. 
Result so far: 120343.94983818
If we take 4944 away from 5420, we end up with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The final result is 120343.94983818 with a remainder of 4.76e-07.
