We're dividing 39887105 by 948 
The aim is to understand the frequency of 948 in 39887105.

Let's proceed to step 1:
948 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 948

Advancing to step 2:
The number 948 fits into 39 0 times, leaving a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 948

Let's proceed to step 3:
The number 948 fits into 398 0 times, leaving a remainder of 398.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 398 and we're left with 398.
Bring next digit (8) of the dividend behind the 398 and repeat the process: 3988 / 948

Moving on to step 4:
948 goes into 3988 4 times with a remainder of 196.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3792 from 3988, we get 196.
Append the next digit (7) from the dividend to 196 and continue with: 1967 / 948

Advancing to step 5:
The number 948 fits into 1967 2 times, leaving a remainder of 71.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 1896 from 1967 and we're left with 71.
Include the next digit (1) from the dividend after 71, then repeat: 711 / 948

On to step 6:
If we divide 711 by 948, we get 0 and a remainder of 711.
Write down 0 as next digit of the result. 
Result so far: 420.0
Subtracting 0 from 711 leaves us with 711.
Bring next digit (0) of the dividend behind the 711 and repeat the process: 7110 / 948

Advancing to step 7:
The number 948 fits into 7110 7 times, leaving a remainder of 474.
The number 7 becomes the next digit in our result. 
Result so far: 4207.0
If we subtract 6636 from 7110, we get 474.
Bring next digit (5) of the dividend behind the 474 and repeat the process: 4745 / 948

Advancing to step 8:
When dividing 4745 by 948, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 42075.0
The remainder is 5 after subtracting 4740 from 4745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 948, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 42075.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 948, we get 0 and a remainder of 500.
The next digit of our result is 0. 
Result so far: 42075.0
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 42075.0, with a leftover of 0.5.
