19875408 ÷ 926 
The aim is to understand the frequency of 926 in 19875408.

Advancing to step 1:
926 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 926

Moving on to step 2:
When dividing 19 by 926, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 926

Let's proceed to step 3:
The number 926 fits into 198 0 times, leaving a remainder of 198.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 198 and we're left with 198.
Take the next digit (7) from the dividend and append it to 198, then repeat: 1987 / 926

Let's proceed to step 4:
When dividing 1987 by 926, we get 2 with a remainder of 135.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1852 away from 1987, we end up with 135.
Fetch the next digit (5) from the dividend, attach it to 135 and continue: 1355 / 926

Let's proceed to step 5:
When dividing 1355 by 926, we get 1 with a remainder of 429.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 926 away from 1355, we end up with 429.
Append the next digit (4) from the dividend to 429 and continue with: 4294 / 926

On to step 6:
The number 926 fits into 4294 4 times, leaving a remainder of 590.
Put 4 as the next digit of the answer. 
Result so far: 214.0
The remainder is 590 after subtracting 3704 from 4294.
Bring next digit (0) of the dividend behind the 590 and repeat the process: 5900 / 926

On to step 7:
926 goes into 5900 6 times with a remainder of 344.
Use 6 as the next digit of our solution. 
Result so far: 2146.0
If we subtract 5556 from 5900, we get 344.
Include the next digit (8) from the dividend after 344, then repeat: 3448 / 926

Step 8:
926 can be fit into 3448 3 times, resulting in a remainder of 670.
Use 3 as the next digit of our solution. 
Result so far: 21463.0
Deduct 2778 from 3448 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

Let's proceed to step 9:
If we divide 6700 by 926, we get 7 and a remainder of 218.
Put 7 as the next digit of the answer. 
Result so far: 21463.7
The remainder is 218 after subtracting 6482 from 6700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 10:
926 goes into 2180 2 times with a remainder of 328.
The number 2 becomes the next digit in our result. 
Result so far: 21463.72
Deduct 1852 from 2180 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 11:
3280 divided by 926 is 3 with a remainder of 502.
Use 3 as the next digit of our solution. 
Result so far: 21463.723
Subtract 2778 from 3280 to get 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Step 12:
926 can be fit into 5020 5 times, resulting in a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 21463.7235
If we take 4630 away from 5020, we end up with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 13:
926 goes into 3900 4 times with a remainder of 196.
The next digit of our result is 4. 
Result so far: 21463.72354
Subtract 3704 from 3900 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 14:
The number 926 fits into 1960 2 times, leaving a remainder of 108.
The next digit of our result is 2. 
Result so far: 21463.723542
Subtract 1852 from 1960 to get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 15:
926 goes into 1080 1 times with a remainder of 154.
Write down 1 as next digit of the result. 
Result so far: 21463.7235421
If we take 926 away from 1080, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 16:
1540 divided by 926 is 1 with a remainder of 614.
The number 1 becomes the next digit in our result. 
Result so far: 21463.72354211
The remainder is 614 after subtracting 926 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

In conclusion, the division gives 21463.72354211 with a balance of 6.14e-07.
