83933307 ÷ 618 
The aim is to understand the frequency of 618 in 83933307.

On to step 1:
If we divide 8 by 618, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 618

Let's proceed to step 2:
618 goes into 83 0 times with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (9) from the dividend, add it to 83, then carry on: 839 / 618

Moving on to step 3:
618 goes into 839 1 times with a remainder of 221.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 221 after subtracting 618 from 839.
Append the next digit (3) from the dividend to 221 and continue with: 2213 / 618

Going ahead to step 4:
618 can be fit into 2213 3 times, resulting in a remainder of 359.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 1854 from 2213 to get 359.
Take the next digit (3) from the dividend and append it to 359, then repeat: 3593 / 618

Advancing to step 5:
If we divide 3593 by 618, we get 5 and a remainder of 503.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Subtracting 3090 from 3593 leaves us with 503.
Take the next digit (3) from the dividend and append it to 503, then repeat: 5033 / 618

Let's proceed to step 6:
618 can be fit into 5033 8 times, resulting in a remainder of 89.
Record the quotient 8 as the next digit in the result. 
Result so far: 1358.0
Subtract 4944 from 5033 to get 89.
Grab the next digit (0) from the dividend, add it to 89, then carry on: 890 / 618

Step 7:
890 divided by 618 is 1 with a remainder of 272.
The number 1 becomes the next digit in our result. 
Result so far: 13581.0
The remainder is 272 after subtracting 618 from 890.
Include the next digit (7) from the dividend after 272, then repeat: 2727 / 618

Step 8:
If we divide 2727 by 618, we get 4 and a remainder of 255.
The next digit of our result is 4. 
Result so far: 135814.0
If we subtract 2472 from 2727, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 9:
The number 618 fits into 2550 4 times, leaving a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 135814.4
Subtracting 2472 from 2550 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
When dividing 780 by 618, we get 1 with a remainder of 162.
Put 1 as the next digit of the answer. 
Result so far: 135814.41
If we take 618 away from 780, we end up with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Going ahead to step 11:
If we divide 1620 by 618, we get 2 and a remainder of 384.
Put 2 as the next digit of the answer. 
Result so far: 135814.412
Deduct 1236 from 1620 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 12:
The number 618 fits into 3840 6 times, leaving a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 135814.4126
If we take 3708 away from 3840, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 13:
If we divide 1320 by 618, we get 2 and a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 135814.41262
Subtract 1236 from 1320 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 14:
618 goes into 840 1 times with a remainder of 222.
The next digit of our result is 1. 
Result so far: 135814.412621
Subtracting 618 from 840 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 15:
618 can be fit into 2220 3 times, resulting in a remainder of 366.
Put 3 as the next digit of the answer. 
Result so far: 135814.4126213
If we take 1854 away from 2220, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 16:
618 can be fit into 3660 5 times, resulting in a remainder of 570.
Record the quotient 5 as the next digit in the result. 
Result so far: 135814.41262135
If we take 3090 away from 3660, we end up with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

After the division, we end up with 135814.41262135 and a remainder of 5.7e-07.
