We divide 85975701 by 30
The aim is to understand the frequency of 30 in 85975701.

Advancing to step 1:
If we divide 8 by 30, 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.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 30

Let's proceed to step 2:
If we divide 85 by 30, we get 2 and a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 60 from 85 and we're left with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 30

Moving on to step 3:
If we divide 259 by 30, we get 8 and a remainder of 19.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 240 from 259 to get 19.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 30

Advancing to step 4:
If we divide 197 by 30, we get 6 and a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 286.0
If we subtract 180 from 197, we get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 30

On to step 5:
If we divide 175 by 30, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2865.0
The remainder is 25 after subtracting 150 from 175.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 30

Going ahead to step 6:
30 goes into 257 8 times with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 28658.0
Deduct 240 from 257 and we're left with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 30

Moving on to step 7:
170 divided by 30 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 286585.0
Subtracting 150 from 170 leaves us with 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 30

Step 8:
30 can be fit into 201 6 times, resulting in a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 2865856.0
Subtract 180 from 201 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
If we divide 210 by 30, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 2865856.7
If we subtract 210 from 210, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
30 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2865856.7
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 30, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2865856.7
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 2865856.7 with a balance of 0.0.
