Let's divide 65749951 by 356
The aim is to understand the frequency of 356 in 65749951.

Advancing to step 1:
When dividing 6 by 356, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 356

On to step 2:
65 divided by 356 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 356

On to step 3:
356 can be fit into 657 1 times, resulting in a remainder of 301.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 356 from 657 and we're left with 301.
Append the next digit (4) from the dividend to 301 and continue with: 3014 / 356

Moving on to step 4:
356 can be fit into 3014 8 times, resulting in a remainder of 166.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 2848 from 3014 to get 166.
Take the next digit (9) from the dividend and append it to 166, then repeat: 1669 / 356

Step 5:
1669 divided by 356 is 4 with a remainder of 245.
Put 4 as the next digit of the answer. 
Result so far: 184.0
Deduct 1424 from 1669 and we're left with 245.
Fetch the next digit (9) from the dividend, attach it to 245 and continue: 2459 / 356

Moving on to step 6:
When dividing 2459 by 356, we get 6 with a remainder of 323.
Put 6 as the next digit of the answer. 
Result so far: 1846.0
Deduct 2136 from 2459 and we're left with 323.
Grab the next digit (5) from the dividend, add it to 323, then carry on: 3235 / 356

Advancing to step 7:
356 goes into 3235 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 18469.0
Subtract 3204 from 3235 to get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 356

Going ahead to step 8:
311 divided by 356 is 0 with a remainder of 311.
The number 0 becomes the next digit in our result. 
Result so far: 184690.0
If we take 0 away from 311, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 9:
The number 356 fits into 3110 8 times, leaving a remainder of 262.
Use 8 as the next digit of our solution. 
Result so far: 184690.8
If we subtract 2848 from 3110, we get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Advancing to step 10:
2620 divided by 356 is 7 with a remainder of 128.
The number 7 becomes the next digit in our result. 
Result so far: 184690.87
Subtracting 2492 from 2620 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 11:
If we divide 1280 by 356, we get 3 and a remainder of 212.
Put 3 as the next digit of the answer. 
Result so far: 184690.873
Subtract 1068 from 1280 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 12:
If we divide 2120 by 356, we get 5 and a remainder of 340.
Put 5 as the next digit of the answer. 
Result so far: 184690.8735
If we take 1780 away from 2120, we end up with 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 13:
If we divide 3400 by 356, we get 9 and a remainder of 196.
Write down 9 as next digit of the result. 
Result so far: 184690.87359
If we subtract 3204 from 3400, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 14:
356 can be fit into 1960 5 times, resulting in a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 184690.873595
Subtracting 1780 from 1960 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 15:
If we divide 1800 by 356, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 184690.8735955
If we subtract 1780 from 1800, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 184690.8735955 and a remainder of 2e-07.
