We're dividing 19963830 by 948 
The aim is to understand the frequency of 948 in 19963830.

On to step 1:
The number 948 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 948

Going ahead to step 2:
When dividing 19 by 948, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 948

Moving on to step 3:
948 can be fit into 199 0 times, resulting in a remainder of 199.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 199 leaves us with 199.
Grab the next digit (6) from the dividend, add it to 199, then carry on: 1996 / 948

Going ahead to step 4:
948 goes into 1996 2 times with a remainder of 100.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1896 away from 1996, we end up with 100.
Include the next digit (3) from the dividend after 100, then repeat: 1003 / 948

Moving on to step 5:
When dividing 1003 by 948, we get 1 with a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 948 from 1003 leaves us with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 948

Step 6:
948 can be fit into 558 0 times, resulting in a remainder of 558.
The next digit of our result is 0. 
Result so far: 210.0
If we take 0 away from 558, we end up with 558.
Take the next digit (3) from the dividend and append it to 558, then repeat: 5583 / 948

Going ahead to step 7:
5583 divided by 948 is 5 with a remainder of 843.
Record the quotient 5 as the next digit in the result. 
Result so far: 2105.0
Subtract 4740 from 5583 to get 843.
Include the next digit (0) from the dividend after 843, then repeat: 8430 / 948

Step 8:
When dividing 8430 by 948, we get 8 with a remainder of 846.
Put 8 as the next digit of the answer. 
Result so far: 21058.0
The remainder is 846 after subtracting 7584 from 8430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

Advancing to step 9:
8460 divided by 948 is 8 with a remainder of 876.
The next digit of our result is 8. 
Result so far: 21058.8
If we subtract 7584 from 8460, we get 876.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8760, and continue the process.

Advancing to step 10:
When dividing 8760 by 948, we get 9 with a remainder of 228.
Record the quotient 9 as the next digit in the result. 
Result so far: 21058.89
If we take 8532 away from 8760, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Step 11:
The number 948 fits into 2280 2 times, leaving a remainder of 384.
The next digit of our result is 2. 
Result so far: 21058.892
The remainder is 384 after subtracting 1896 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Going ahead to step 12:
3840 divided by 948 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 21058.8924
Deduct 3792 from 3840 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
When dividing 480 by 948, we get 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 21058.8924
Subtract 0 from 480 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 14:
4800 divided by 948 is 5 with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 21058.892405
Deduct 4740 from 4800 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 15:
If we divide 600 by 948, we get 0 and a remainder of 600.
Put 0 as the next digit of the answer. 
Result so far: 21058.892405
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 16:
948 can be fit into 6000 6 times, resulting in a remainder of 312.
The next digit of our result is 6. 
Result so far: 21058.89240506
If we subtract 5688 from 6000, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The quotient of the division is 21058.89240506, and the remainder is 3.12e-07.
