75202766 ÷ 215 
The aim is to understand the frequency of 215 in 75202766.

Let's proceed to step 1:
7 divided by 215 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 215

Advancing to step 2:
The number 215 fits into 75 0 times, leaving a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Append the next digit (2) from the dividend to 75 and continue with: 752 / 215

Step 3:
If we divide 752 by 215, we get 3 and a remainder of 107.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 645 away from 752, we end up with 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 215

On to step 4:
1070 divided by 215 is 4 with a remainder of 210.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 860 from 1070 and we're left with 210.
Fetch the next digit (2) from the dividend, attach it to 210 and continue: 2102 / 215

Going ahead to step 5:
If we divide 2102 by 215, we get 9 and a remainder of 167.
Record the quotient 9 as the next digit in the result. 
Result so far: 349.0
Deduct 1935 from 2102 and we're left with 167.
Take the next digit (7) from the dividend and append it to 167, then repeat: 1677 / 215

On to step 6:
If we divide 1677 by 215, we get 7 and a remainder of 172.
The next digit of our result is 7. 
Result so far: 3497.0
Subtracting 1505 from 1677 leaves us with 172.
Append the next digit (6) from the dividend to 172 and continue with: 1726 / 215

Advancing to step 7:
215 goes into 1726 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 34978.0
If we subtract 1720 from 1726, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 215

Let's proceed to step 8:
The number 215 fits into 66 0 times, leaving a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 349780.0
If we subtract 0 from 66, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
215 can be fit into 660 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 349780.3
Deduct 645 from 660 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
If we divide 150 by 215, we get 0 and a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 349780.3
The remainder is 150 after subtracting 0 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
If we divide 1500 by 215, we get 6 and a remainder of 210.
Write down 6 as next digit of the result. 
Result so far: 349780.306
Deduct 1290 from 1500 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 12:
When dividing 2100 by 215, we get 9 with a remainder of 165.
Write down 9 as next digit of the result. 
Result so far: 349780.3069
The remainder is 165 after subtracting 1935 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 13:
1650 divided by 215 is 7 with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 349780.30697
If we subtract 1505 from 1650, we get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 14:
215 can be fit into 1450 6 times, resulting in a remainder of 160.
The next digit of our result is 6. 
Result so far: 349780.306976
The remainder is 160 after subtracting 1290 from 1450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
1600 divided by 215 is 7 with a remainder of 95.
The number 7 becomes the next digit in our result. 
Result so far: 349780.3069767
If we take 1505 away from 1600, we end up with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 16:
950 divided by 215 is 4 with a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 349780.30697674
Deduct 860 from 950 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

In conclusion, the division gives 349780.30697674 with a balance of 9e-08.
