Let's divide 90476372 by 415
The aim is to understand the frequency of 415 in 90476372.

Moving on to step 1:
If we divide 9 by 415, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 415

Going ahead to step 2:
When dividing 90 by 415, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 415

On to step 3:
When dividing 904 by 415, we get 2 with a remainder of 74.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 830 from 904 leaves us with 74.
Grab the next digit (7) from the dividend, add it to 74, then carry on: 747 / 415

On to step 4:
The number 415 fits into 747 1 times, leaving a remainder of 332.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 415 from 747 to get 332.
Take the next digit (6) from the dividend and append it to 332, then repeat: 3326 / 415

Advancing to step 5:
415 goes into 3326 8 times with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 218.0
The remainder is 6 after subtracting 3320 from 3326.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 415

On to step 6:
When dividing 63 by 415, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 2180.0
If we subtract 0 from 63, we get 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 415

Going ahead to step 7:
When dividing 637 by 415, we get 1 with a remainder of 222.
Record the quotient 1 as the next digit in the result. 
Result so far: 21801.0
The remainder is 222 after subtracting 415 from 637.
Grab the next digit (2) from the dividend, add it to 222, then carry on: 2222 / 415

Let's proceed to step 8:
415 goes into 2222 5 times with a remainder of 147.
The next digit of our result is 5. 
Result so far: 218015.0
Subtracting 2075 from 2222 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
When dividing 1470 by 415, we get 3 with a remainder of 225.
Use 3 as the next digit of our solution. 
Result so far: 218015.3
If we take 1245 away from 1470, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 10:
If we divide 2250 by 415, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 218015.35
If we take 2075 away from 2250, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 11:
415 can be fit into 1750 4 times, resulting in a remainder of 90.
The number 4 becomes the next digit in our result. 
Result so far: 218015.354
Deduct 1660 from 1750 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.

Moving on to step 12:
If we divide 900 by 415, we get 2 and a remainder of 70.
Use 2 as the next digit of our solution. 
Result so far: 218015.3542
Subtract 830 from 900 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 13:
When dividing 700 by 415, we get 1 with a remainder of 285.
Write down 1 as next digit of the result. 
Result so far: 218015.35421
The remainder is 285 after subtracting 415 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 14:
415 goes into 2850 6 times with a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 218015.354216
If we take 2490 away from 2850, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 15:
415 can be fit into 3600 8 times, resulting in a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 218015.3542168
If we subtract 3320 from 3600, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 16:
415 can be fit into 2800 6 times, resulting in a remainder of 310.
Put 6 as the next digit of the answer. 
Result so far: 218015.35421686
If we take 2490 away from 2800, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Our division results in 218015.35421686 with a remaining 3.1e-07.
