Let's divide 70629080 by 415
The aim is to understand the frequency of 415 in 70629080.

Advancing to step 1:
The number 415 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 415

Let's proceed to step 2:
When dividing 70 by 415, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Append the next digit (6) from the dividend to 70 and continue with: 706 / 415

Advancing to step 3:
When dividing 706 by 415, we get 1 with a remainder of 291.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 415 from 706 leaves us with 291.
Fetch the next digit (2) from the dividend, attach it to 291 and continue: 2912 / 415

Advancing to step 4:
If we divide 2912 by 415, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 17.0
The remainder is 7 after subtracting 2905 from 2912.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 415

On to step 5:
If we divide 79 by 415, we get 0 and a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 170.0
If we subtract 0 from 79, we get 79.
Bring next digit (0) of the dividend behind the 79 and repeat the process: 790 / 415

Step 6:
If we divide 790 by 415, we get 1 and a remainder of 375.
Write down 1 as next digit of the result. 
Result so far: 1701.0
Subtract 415 from 790 to get 375.
Grab the next digit (8) from the dividend, add it to 375, then carry on: 3758 / 415

On to step 7:
415 can be fit into 3758 9 times, resulting in a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 17019.0
If we subtract 3735 from 3758, we get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 415

On to step 8:
When dividing 230 by 415, we get 0 with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 170190.0
Subtract 0 from 230 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 9:
2300 divided by 415 is 5 with a remainder of 225.
Use 5 as the next digit of our solution. 
Result so far: 170190.5
If we subtract 2075 from 2300, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 10:
2250 divided by 415 is 5 with a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 170190.55
Deduct 2075 from 2250 and we're left 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.

After the division, we end up with 170190.55 and a remainder of 0.175.
