We divide 42488838 by 915
The aim is to understand the frequency of 915 in 42488838.

On to step 1:
915 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 915

Step 2:
When dividing 42 by 915, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (4) from the dividend to 42 and continue with: 424 / 915

Going ahead to step 3:
915 can be fit into 424 0 times, resulting in a remainder of 424.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 424 leaves us with 424.
Take the next digit (8) from the dividend and append it to 424, then repeat: 4248 / 915

Moving on to step 4:
4248 divided by 915 is 4 with a remainder of 588.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 588 after subtracting 3660 from 4248.
Fetch the next digit (8) from the dividend, attach it to 588 and continue: 5888 / 915

On to step 5:
When dividing 5888 by 915, we get 6 with a remainder of 398.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Subtracting 5490 from 5888 leaves us with 398.
Append the next digit (8) from the dividend to 398 and continue with: 3988 / 915

Step 6:
The number 915 fits into 3988 4 times, leaving a remainder of 328.
Record the quotient 4 as the next digit in the result. 
Result so far: 464.0
If we subtract 3660 from 3988, we get 328.
Bring next digit (3) of the dividend behind the 328 and repeat the process: 3283 / 915

Going ahead to step 7:
If we divide 3283 by 915, we get 3 and a remainder of 538.
Record the quotient 3 as the next digit in the result. 
Result so far: 4643.0
If we subtract 2745 from 3283, we get 538.
Append the next digit (8) from the dividend to 538 and continue with: 5388 / 915

On to step 8:
When dividing 5388 by 915, we get 5 with a remainder of 813.
Use 5 as the next digit of our solution. 
Result so far: 46435.0
The remainder is 813 after subtracting 4575 from 5388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8130, and continue the process.

Step 9:
8130 divided by 915 is 8 with a remainder of 810.
The next digit of our result is 8. 
Result so far: 46435.8
If we take 7320 away from 8130, we end up with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Advancing to step 10:
When dividing 8100 by 915, we get 8 with a remainder of 780.
The number 8 becomes the next digit in our result. 
Result so far: 46435.88
Deduct 7320 from 8100 and we're left with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

The final outcome is 46435.88, with a leftover of 0.78.
