We look at the division of 80215235 by 933 
The aim is to understand the frequency of 933 in 80215235.

Going ahead to step 1:
If we divide 8 by 933, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 933

Step 2:
The number 933 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 933

Advancing to step 3:
The number 933 fits into 802 0 times, leaving a remainder of 802.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 802, we get 802.
Grab the next digit (1) from the dividend, add it to 802, then carry on: 8021 / 933

Advancing to step 4:
933 can be fit into 8021 8 times, resulting in a remainder of 557.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 7464 away from 8021, we end up with 557.
Take the next digit (5) from the dividend and append it to 557, then repeat: 5575 / 933

Step 5:
5575 divided by 933 is 5 with a remainder of 910.
Use 5 as the next digit of our solution. 
Result so far: 85.0
If we take 4665 away from 5575, we end up with 910.
Include the next digit (2) from the dividend after 910, then repeat: 9102 / 933

Step 6:
9102 divided by 933 is 9 with a remainder of 705.
Use 9 as the next digit of our solution. 
Result so far: 859.0
Deduct 8397 from 9102 and we're left with 705.
Grab the next digit (3) from the dividend, add it to 705, then carry on: 7053 / 933

Going ahead to step 7:
933 goes into 7053 7 times with a remainder of 522.
Record the quotient 7 as the next digit in the result. 
Result so far: 8597.0
Subtract 6531 from 7053 to get 522.
Fetch the next digit (5) from the dividend, attach it to 522 and continue: 5225 / 933

Step 8:
933 goes into 5225 5 times with a remainder of 560.
Record the quotient 5 as the next digit in the result. 
Result so far: 85975.0
Subtract 4665 from 5225 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 9:
If we divide 5600 by 933, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 85975.6
If we subtract 5598 from 5600, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
933 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 85975.6
If we subtract 0 from 20, 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.

Step 11:
When dividing 200 by 933, we get 0 with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 85975.6
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 85975.6, with a leftover of 0.02.
