10189791 ÷ 426 
The aim is to understand the frequency of 426 in 10189791.

Let's proceed to step 1:
426 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 426

On to step 2:
The number 426 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 426

Going ahead to step 3:
The number 426 fits into 101 0 times, leaving a remainder of 101.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 101 leaves us with 101.
Fetch the next digit (8) from the dividend, attach it to 101 and continue: 1018 / 426

Moving on to step 4:
1018 divided by 426 is 2 with a remainder of 166.
The next digit of our result is 2. 
Result so far: 2.0
If we take 852 away from 1018, we end up with 166.
Append the next digit (9) from the dividend to 166 and continue with: 1669 / 426

On to step 5:
426 can be fit into 1669 3 times, resulting in a remainder of 391.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 1278 away from 1669, we end up with 391.
Fetch the next digit (7) from the dividend, attach it to 391 and continue: 3917 / 426

Advancing to step 6:
3917 divided by 426 is 9 with a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
Subtract 3834 from 3917 to get 83.
Bring next digit (9) of the dividend behind the 83 and repeat the process: 839 / 426

On to step 7:
426 can be fit into 839 1 times, resulting in a remainder of 413.
Use 1 as the next digit of our solution. 
Result so far: 2391.0
If we subtract 426 from 839, we get 413.
Append the next digit (1) from the dividend to 413 and continue with: 4131 / 426

On to step 8:
The number 426 fits into 4131 9 times, leaving a remainder of 297.
Write down 9 as next digit of the result. 
Result so far: 23919.0
Subtracting 3834 from 4131 leaves us with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Going ahead to step 9:
426 can be fit into 2970 6 times, resulting in a remainder of 414.
The next digit of our result is 6. 
Result so far: 23919.6
Deduct 2556 from 2970 and we're left with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 10:
426 can be fit into 4140 9 times, resulting in a remainder of 306.
The number 9 becomes the next digit in our result. 
Result so far: 23919.69
Subtract 3834 from 4140 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 11:
3060 divided by 426 is 7 with a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 23919.697
Subtracting 2982 from 3060 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 12:
The number 426 fits into 780 1 times, leaving a remainder of 354.
Put 1 as the next digit of the answer. 
Result so far: 23919.6971
Subtract 426 from 780 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 13:
When dividing 3540 by 426, we get 8 with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 23919.69718
Subtracting 3408 from 3540 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 14:
426 goes into 1320 3 times with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 23919.697183
The remainder is 42 after subtracting 1278 from 1320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 15:
420 divided by 426 is 0 with a remainder of 420.
The next digit of our result is 0. 
Result so far: 23919.697183
If we subtract 0 from 420, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 16:
If we divide 4200 by 426, we get 9 and a remainder of 366.
Write down 9 as next digit of the result. 
Result so far: 23919.69718309
The remainder is 366 after subtracting 3834 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

In conclusion, the division gives 23919.69718309 with a balance of 3.66e-07.
