39197521 ÷ 948 
The aim is to understand the frequency of 948 in 39197521.

Going ahead to step 1:
The number 948 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 948

Advancing to step 2:
948 can be fit into 39 0 times, resulting in 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 (1) from the dividend and append it to 39, then repeat: 391 / 948

Step 3:
If we divide 391 by 948, we get 0 and a remainder of 391.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 391 after subtracting 0 from 391.
Append the next digit (9) from the dividend to 391 and continue with: 3919 / 948

On to step 4:
If we divide 3919 by 948, we get 4 and a remainder of 127.
The next digit of our result is 4. 
Result so far: 4.0
If we take 3792 away from 3919, we end up with 127.
Append the next digit (7) from the dividend to 127 and continue with: 1277 / 948

Let's proceed to step 5:
1277 divided by 948 is 1 with a remainder of 329.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Subtract 948 from 1277 to get 329.
Fetch the next digit (5) from the dividend, attach it to 329 and continue: 3295 / 948

Step 6:
When dividing 3295 by 948, we get 3 with a remainder of 451.
The next digit of our result is 3. 
Result so far: 413.0
If we subtract 2844 from 3295, we get 451.
Include the next digit (2) from the dividend after 451, then repeat: 4512 / 948

Step 7:
When dividing 4512 by 948, we get 4 with a remainder of 720.
The number 4 becomes the next digit in our result. 
Result so far: 4134.0
If we take 3792 away from 4512, we end up with 720.
Append the next digit (1) from the dividend to 720 and continue with: 7201 / 948

Let's proceed to step 8:
If we divide 7201 by 948, we get 7 and a remainder of 565.
The number 7 becomes the next digit in our result. 
Result so far: 41347.0
Subtract 6636 from 7201 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 9:
If we divide 5650 by 948, we get 5 and a remainder of 910.
The next digit of our result is 5. 
Result so far: 41347.5
Deduct 4740 from 5650 and we're left with 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9100, and continue the process.

Advancing to step 10:
948 can be fit into 9100 9 times, resulting in a remainder of 568.
Write down 9 as next digit of the result. 
Result so far: 41347.59
Subtract 8532 from 9100 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 11:
5680 divided by 948 is 5 with a remainder of 940.
The next digit of our result is 5. 
Result so far: 41347.595
If we subtract 4740 from 5680, we get 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9400, and continue the process.

Advancing to step 12:
The number 948 fits into 9400 9 times, leaving a remainder of 868.
Write down 9 as next digit of the result. 
Result so far: 41347.5959
Subtract 8532 from 9400 to get 868.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8680, and continue the process.

Moving on to step 13:
8680 divided by 948 is 9 with a remainder of 148.
Record the quotient 9 as the next digit in the result. 
Result so far: 41347.59599
The remainder is 148 after subtracting 8532 from 8680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

After the division, we end up with 41347.59599 and a remainder of 0.000148.
