90188685 ÷ 333 
The aim is to understand the frequency of 333 in 90188685.

Step 1:
If we divide 9 by 333, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 333

Advancing to step 2:
333 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 333

On to step 3:
333 goes into 901 2 times with a remainder of 235.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 666 from 901, we get 235.
Fetch the next digit (8) from the dividend, attach it to 235 and continue: 2358 / 333

Step 4:
When dividing 2358 by 333, we get 7 with a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 2331 away from 2358, we end up with 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 333

On to step 5:
333 can be fit into 278 0 times, resulting in a remainder of 278.
The next digit of our result is 0. 
Result so far: 270.0
Deduct 0 from 278 and we're left with 278.
Bring next digit (6) of the dividend behind the 278 and repeat the process: 2786 / 333

On to step 6:
333 goes into 2786 8 times with a remainder of 122.
Write down 8 as next digit of the result. 
Result so far: 2708.0
If we subtract 2664 from 2786, we get 122.
Grab the next digit (8) from the dividend, add it to 122, then carry on: 1228 / 333

Advancing to step 7:
333 can be fit into 1228 3 times, resulting in a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 27083.0
Subtract 999 from 1228 to get 229.
Bring next digit (5) of the dividend behind the 229 and repeat the process: 2295 / 333

On to step 8:
When dividing 2295 by 333, we get 6 with a remainder of 297.
Write down 6 as next digit of the result. 
Result so far: 270836.0
Subtract 1998 from 2295 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 9:
When dividing 2970 by 333, we get 8 with a remainder of 306.
Put 8 as the next digit of the answer. 
Result so far: 270836.8
Subtract 2664 from 2970 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 10:
333 goes into 3060 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 270836.89
If we take 2997 away from 3060, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 11:
333 can be fit into 630 1 times, resulting in a remainder of 297.
The number 1 becomes the next digit in our result. 
Result so far: 270836.891
If we take 333 away from 630, we end up with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

On to step 12:
When dividing 2970 by 333, we get 8 with a remainder of 306.
The next digit of our result is 8. 
Result so far: 270836.8918
The remainder is 306 after subtracting 2664 from 2970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Let's proceed to step 13:
The number 333 fits into 3060 9 times, leaving a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 270836.89189
If we take 2997 away from 3060, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 14:
333 goes into 630 1 times with a remainder of 297.
The next digit of our result is 1. 
Result so far: 270836.891891
Deduct 333 from 630 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 15:
333 goes into 2970 8 times with a remainder of 306.
Use 8 as the next digit of our solution. 
Result so far: 270836.8918918
Subtract 2664 from 2970 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Moving on to step 16:
If we divide 3060 by 333, we get 9 and a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 270836.89189189
Subtracting 2997 from 3060 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

After the division, we end up with 270836.89189189 and a remainder of 6.3e-08.
