86728244 divided by 357 
The aim is to understand the frequency of 357 in 86728244.

Going ahead to step 1:
If we divide 8 by 357, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 357

Advancing to step 2:
86 divided by 357 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Fetch the next digit (7) from the dividend, attach it to 86 and continue: 867 / 357

Advancing to step 3:
867 divided by 357 is 2 with a remainder of 153.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 153 after subtracting 714 from 867.
Bring next digit (2) of the dividend behind the 153 and repeat the process: 1532 / 357

Going ahead to step 4:
The number 357 fits into 1532 4 times, leaving a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 1428 from 1532 to get 104.
Grab the next digit (8) from the dividend, add it to 104, then carry on: 1048 / 357

On to step 5:
When dividing 1048 by 357, we get 2 with a remainder of 334.
The next digit of our result is 2. 
Result so far: 242.0
If we subtract 714 from 1048, we get 334.
Append the next digit (2) from the dividend to 334 and continue with: 3342 / 357

Step 6:
When dividing 3342 by 357, we get 9 with a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 2429.0
Subtracting 3213 from 3342 leaves us with 129.
Take the next digit (4) from the dividend and append it to 129, then repeat: 1294 / 357

On to step 7:
357 can be fit into 1294 3 times, resulting in a remainder of 223.
The next digit of our result is 3. 
Result so far: 24293.0
If we subtract 1071 from 1294, we get 223.
Grab the next digit (4) from the dividend, add it to 223, then carry on: 2234 / 357

Let's proceed to step 8:
When dividing 2234 by 357, we get 6 with a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 242936.0
If we subtract 2142 from 2234, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 9:
When dividing 920 by 357, we get 2 with a remainder of 206.
The next digit of our result is 2. 
Result so far: 242936.2
Subtract 714 from 920 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

On to step 10:
If we divide 2060 by 357, we get 5 and a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 242936.25
Subtract 1785 from 2060 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 11:
357 can be fit into 2750 7 times, resulting in a remainder of 251.
The number 7 becomes the next digit in our result. 
Result so far: 242936.257
Deduct 2499 from 2750 and we're left with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

On to step 12:
2510 divided by 357 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 242936.2577
If we subtract 2499 from 2510, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The quotient of the division is 242936.2577, and the remainder is 0.00011.
