We look at the division of 81634234 by 357 
The aim is to understand the frequency of 357 in 81634234.

Let's proceed to step 1:
357 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 357

Let's proceed to step 2:
81 divided by 357 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 357

Moving on to step 3:
If we divide 816 by 357, we get 2 and a remainder of 102.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 714 from 816 to get 102.
Grab the next digit (3) from the dividend, add it to 102, then carry on: 1023 / 357

Moving on to step 4:
357 can be fit into 1023 2 times, resulting in a remainder of 309.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtracting 714 from 1023 leaves us with 309.
Fetch the next digit (4) from the dividend, attach it to 309 and continue: 3094 / 357

Going ahead to step 5:
If we divide 3094 by 357, we get 8 and a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Deduct 2856 from 3094 and we're left with 238.
Append the next digit (2) from the dividend to 238 and continue with: 2382 / 357

Advancing to step 6:
If we divide 2382 by 357, we get 6 and a remainder of 240.
Write down 6 as next digit of the result. 
Result so far: 2286.0
Subtract 2142 from 2382 to get 240.
Append the next digit (3) from the dividend to 240 and continue with: 2403 / 357

Going ahead to step 7:
357 goes into 2403 6 times with a remainder of 261.
Write down 6 as next digit of the result. 
Result so far: 22866.0
Subtracting 2142 from 2403 leaves us with 261.
Fetch the next digit (4) from the dividend, attach it to 261 and continue: 2614 / 357

Let's proceed to step 8:
When dividing 2614 by 357, we get 7 with a remainder of 115.
Put 7 as the next digit of the answer. 
Result so far: 228667.0
Subtracting 2499 from 2614 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 9:
If we divide 1150 by 357, we get 3 and a remainder of 79.
Put 3 as the next digit of the answer. 
Result so far: 228667.3
Deduct 1071 from 1150 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 10:
If we divide 790 by 357, we get 2 and a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 228667.32
Deduct 714 from 790 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
The number 357 fits into 760 2 times, leaving a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 228667.322
Subtract 714 from 760 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 228667.322, and the remainder is 0.0046.
