We divide 64627383 by 415
The aim is to understand the frequency of 415 in 64627383.

Step 1:
When dividing 6 by 415, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 415

Going ahead to step 2:
64 divided by 415 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 415

Going ahead to step 3:
The number 415 fits into 646 1 times, leaving a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 415 from 646 and we're left with 231.
Bring next digit (2) of the dividend behind the 231 and repeat the process: 2312 / 415

Step 4:
If we divide 2312 by 415, we get 5 and a remainder of 237.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 2075 from 2312, we get 237.
Include the next digit (7) from the dividend after 237, then repeat: 2377 / 415

Let's proceed to step 5:
2377 divided by 415 is 5 with a remainder of 302.
The next digit of our result is 5. 
Result so far: 155.0
The remainder is 302 after subtracting 2075 from 2377.
Include the next digit (3) from the dividend after 302, then repeat: 3023 / 415

Moving on to step 6:
If we divide 3023 by 415, we get 7 and a remainder of 118.
Use 7 as the next digit of our solution. 
Result so far: 1557.0
Deduct 2905 from 3023 and we're left with 118.
Grab the next digit (8) from the dividend, add it to 118, then carry on: 1188 / 415

Advancing to step 7:
1188 divided by 415 is 2 with a remainder of 358.
Write down 2 as next digit of the result. 
Result so far: 15572.0
The remainder is 358 after subtracting 830 from 1188.
Grab the next digit (3) from the dividend, add it to 358, then carry on: 3583 / 415

Step 8:
If we divide 3583 by 415, we get 8 and a remainder of 263.
Put 8 as the next digit of the answer. 
Result so far: 155728.0
Deduct 3320 from 3583 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Moving on to step 9:
When dividing 2630 by 415, we get 6 with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 155728.6
If we take 2490 away from 2630, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
1400 divided by 415 is 3 with a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 155728.63
If we subtract 1245 from 1400, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 11:
415 goes into 1550 3 times with a remainder of 305.
The number 3 becomes the next digit in our result. 
Result so far: 155728.633
Subtract 1245 from 1550 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The quotient of the division is 155728.633, and the remainder is 0.0305.
